Select from the topics below to learn more about winter driving and the Idaho Transportation Department’s efforts to keep Idaho’s highway system safe and clear during the snow season.
How does the Idaho Transportation Department keep highways clear in the winter?
ITD monitors the weather to determine when to use which applications on our roads to keep them safe. ITD uses anti-icing applications such as liquid salt brine and magnesium chloride before the storm hits to prevent ice from forming. During the storm, ITD plows the roads and applies de-icing solutions such as solid salt to burn through the snow on the road.
ITD is a global leader in using the most current data to drive decision making for winter operations. More than a dozen other countries have contacted ITD about our process.
To minimize effects to vehicles and the environment, ITD uses the least amount of salt to keep the roads safe.
Why do we use salt in winter road maintenance?
Salt is very effective in keeping our roads clear and safe.
ITD has used a salt and sand mixture in winter-maintenance efforts since the 1960s. ITD uses in excess of 100 million lbs. of salt and salt brine each winter to clear 12,200 lane miles of highway – more material depending on the severity of the winter.
Using salt increases the effectiveness of the sanding material by adding a snow- and ice-melting agent to improve traction. Additionally, it keeps stockpiles of sand from freezing solid.
Over the years, some regions began using liquid salt solutions of magnesium chloride as a de-icer on the roadways. Others switched to a salt brine solution to increase efficiency and lower costs in areas where it could be effective. Salt continues to be a key component to these efforts.
Because of the use of salt, there has been significant decreases in winter road incidents in winter months. In fact, the only months that have shown a recent decline in fatalities and serious injury crashes have been December-February, when salt use on our highways is heaviest.
A result of using salts to maximize safety on the highways is vehicle corrosion, particularly the undercarriage. It has been a problem for many decades, with various solutions suggested.
ITD uses sodium chloride salt, which is corrosive to iron and steel but has less impact on aluminum and copper. Auto manufacturers regularly apply protective coatings, so corrosion is reduced on modern vehicles. Transportation agencies also have experimented with buffering agents added into the salt.
Application rates for straight salt are considerably less than for sanding material. ITD has learned that one truckload of straight salt would treat the same length of roadway as six truckloads of the salt/sand mixture. In other words, the same amount of salt was used in both applications, but we were using a lot less sanding material.
For liquid applications, the amount placed on the roadway varies with the purpose of the application. For anti-icing applications, liquids are applied just before the storm. For solid applications, ITD applies salt behind the snowplow to help melt the remaining snow and ice.
The best method to minimize corrosion available today is the careful use of salt. The application rates used by ITD are far below that commonly used in the Mid-Western States. At ITD, we take advantage of lessons learned, and have found that we can be very effective with far less material. In some of the areas of the state, such as northern Idaho, the weather is more temperate, with heavy, wet snow that works the best with the salt program.
Washing vehicles frequently will also help minimize corrosion.
Salt keeps our roads safe, but it can build up on our vehicles, especially the undercarriage, and may cause damage to the underside of cars. It is important to prevent buildup by washing your car often during the winter months, preferably every week. If you go to a car wash, select an option that cleans the underside of your car. If you go to a carwash that only has wands, try to pay special attention to the wheels.
Studies show that our usage of salt does not permanently affect the environment.
ITD measures how much salt our trucks use every year to make sure the least amount of salt is used to minimize effects to the environment and to vehicles.
The Idaho Department of Environmental Quality has conducted a multi-year study investigating environmental quality of water bodies along I-90. This study showed that salt concentrations in these water bodies never reached thresholds dangerous to plants, wildlife, or humans. Small increases of salt concentration during the winter were temporary and were flushed with the spring runoff.
The temporary “browning” condition noticeable on the trees lining the highway is a seasonal occurrence, the result of winter roadway maintenance.
Salts pull moisture from the needles, causing them to dehydrate and brown. The needles fall off once the new annual growth emerges. By mid-summer, the trees are typically green again.
Although trees add to the roadside scenery of Idaho, they can pose a threat to the traveling public. Trees shade some parts of the road, allowing ice to form in the winter. In the event of a storm, trees can fall onto the roadway. Roadside vegetation can also limit line of sight while driving and disguise wildlife near or on the roadway.
Salt for Safety
Remember, ITD uses salt on the road to keep them as safe and clear as possible, and only uses as much salt as necessary to do the job. Please remember to clean your vehicle during the winter months, and call 5-1-1 or visit 511.Idaho.gov for the latest conditions on Idaho highways.
Most of us can’t put our lives on hold when it snows. That’s why the Idaho Transportation Department strives to make winter travel as safe as possible on state highways. Although many drivers have watched snowplows clear the roads, there are some important facts you should know about snow removal.
How does ITD prepare for the snow and ice season?
During the year, more than 400 ITD operations personnel prepare for the snow season by stockpiling necessary supplies. In the fall, the same trucks that have been used during the summer for stockpiling, patching and other maintenance operations are equipped with snowplows. Employees also receive training to operate new equipment.
How does ITD decide which roads to clear first?
ITD considers these factors for clearing roads in the state highway system:
- Traffic volumes
- Accident reduction
- Number of steep grades, sharp curves, intersections, ramps or potentially hazardous areas
- Availability of manpower and equipment resources
ITD applies liquid anti-icers to roads in many areas before a storm arrives. Once the anti-icing work is completed, ITD responds to winter storms as they occur and attempts to clear all roads as the snow begins to fall. However, in situations where a storm covers a large area, resources can be stretched beyond available limits. In these situations a system of priorities is followed to provide the best service.
Interstates and state highways that have the highest volume of traffic are cleared first. Workers continue to clear roads with top priority placed on the most-traveled roads down to areas with lower volumes of traffic.
Some routes, because of concerns for public safety, high difficulty and cost of winter maintenance, may be closed for short durations until manpower and equipment resources are available for snow removal.
The winter maintenance priorities on the state highway system are approved by the Idaho Transportation Board.
How can drivers help when the roads are being cleared?
Use caution when driving in winter conditions, and cooperate with the highway workers that clear the roadways. Here are some additional safety tips:
- Remain two car lengths behind snowplow trucks for every 10 mph you drive. Sand being spread by trucks can damage your vehicle.
- Do not pass a snowplow unless it is absolutely necessary. If you must pass, do so only when you can clearly see the road ahead. Do not pass on the side where the plow is spraying snow. If you do, the snow’s force can knock your car out of control.
- Do not cut back immediately in front of a snowplow truck. The plow blades are often covered with snow and can be difficult to see.
- Do not brake suddenly if you are traveling in front of a snowplow. The heavy vehicle cannot stop as quickly as an automobile.
- Do not abandon your car unless it is absolutely necessary. However, if you must, leave it as far off the road as possible. Abandoned cars can interfere with the road clearing process and can be extremely hazardous to snow removal equipment and the operators if they are hidden or buried by snow.
- Be aware of potential icy areas such as shady spots, bridges and overpasses. Since they are exposed on their undersides, bridges and overpasses are deprived of ground warmth and freeze more rapidly than the roadways leading to them.
- Before you begin your trip, make sure your car’s windows, mirrors and lights are clear of snow. Keep your windshield washers filled with a non-freezing solution all winter.
- Keep an emergency winter driving kit in your car. The kit should include: flashlights with extra batteries, a first aid kit with a pocket knife, at least one blanket, an extra set of mittens, socks and a wool cap, a small sack of sand or cat litter for generating traction under the wheels, a small shovel, bottled water, booster cables, canned fruit, nuts and a non-electric can opener.
- Travel Smart. Travel Safe. Get updates on winter road and weather conditions, emergency closures and access to tourist information 24-hours-a-day by visiting 511.idaho.gov or dialing 511. If your phone company does not support 511, simply call 888-IDA-ROAD (888-432-7623) to access the 511 system.
What should be done if a medical emergency occurs in an area where the roads have not been cleared?
In case of medical emergencies in areas where roads have not been plowed, the local or state police should be called. These agencies will work with search and rescue personnel and ITD to respond to emergencies.
Winter Driving Checklist
For Idaho motorists, winter driving is a necessity. Drivers can help ensure safer travel by preparing themselves and their vehicles for the cooler months ahead.
Even the most cautious driver should carry some essential items in the car in case of an emergency. Use a plastic crate or a large, heavy canvas bag to store the following items in the trunk of your car:
- Flashlights with extra batteries
- First aid kit with a pocket knife
- At least one blanket
- Extra set of mittens, socks and a wool cap
- Small sack of sand or cat litter for generating traction under the wheels
- A small shovel
- Bottled water
- Jumper cables
- Window washer solvent
- Ice scraper with brush
- Cloth or roll of paper towels
- Warning devices (flares or triangles)
- Basic toolkit (screwdrivers, pliers, adjustable wrench)
- Mobile phone and car charger pre-programmed with rescue apps and important phone numbers including family and emergency services
- Non-perishable snacks for both human and pet passengers
- Canned fruit, nuts and a non-electric can opener
Winter Car Care Checklist
A winter car kit helps ensure a driver’s safety, but vehicles also need attention at the start of the winter season. The American Automobile Association (AAA) advises drivers prepare their vehicles for the winter season:
- Battery and Charging System – Have the battery and charging system tested by a trained technician. A fully charged battery in good condition is required to start an engine in cold weather.
- Battery Cables and Terminals – Make sure the battery terminals and cable ends are free from corrosion, and the connections are tight.
- Drive Belts – Inspect the underside of accessory drive belts for cracks or fraying. Many newer multi-rib “serpentine” belts are made of materials that do not show obvious signs of wear; replace these belts at 60,000-mile intervals.
- Engine Hoses – Inspect cooling system hoses for leaks, cracks or loose clamps. Also, squeeze the hoses and replace any that are brittle or excessively spongy feeling.
- Tire Type and Tread – In areas with heavy winter weather, installing snow tires on all four wheels will provide the best winter traction. All-season tires work well in light to moderate snow conditions, provided they have adequate tread depth. Replace any tire that has less than 3/32-inches of tread. Uneven tire wear can indicate misalignment, or wheel balance/suspension problems that must be addressed to prevent further tire damage.
- Tire Pressure – Check tire inflation pressure more frequently in fall and winter. As the average temperature drops, so will tire pressures – typically by 1 PSI for every 10 degrees Fahrenheit. The proper tire pressure levels can be in the owner’s manual or on a sticker typically located on the driver’s side door jamb. Also, check the spare.
- Air Filter – Check the engine air filter by holding it up to a 60-watt light bulb. If light can be seen through much of the filter, it is still clean enough to work effectively. However, if light is blocked by most of the filter, replace it.
- Coolant Levels – Check the coolant level in the overflow tank when the engine is cold. If the level is low, add a 50/50 solution of coolant and water to maintain the necessary antifreeze capability. Test the antifreeze protection level with an inexpensive tester available at any auto parts store.
- Lights – Check the operation of all headlights, taillights, brake lights, turn signals, emergency flashers, and back-up lights. Replace any burnt out bulbs.
- Wiper Blades – The blades should completely clear the glass with each swipe. Replace any blade that leaves streaks or misses spots. In areas with snow, consider installing winter wiper blades that wrap the blade frame in a rubber boot to reduce ice and snow buildup that can prevent good contact between the blade and the glass.
- Washer Fluid – Fill the windshield washer fluid reservoir with a winter cleaning solution that has antifreeze components to prevent freezing.
- Brakes – If there is any indication of a brake problem, have the system inspected by a certified technician to ensure all components are in good working order.
- Transmission, Brake and Power Steering Fluids – Check all fluids to ensure they are at or above the minimum safe levels.
Facts about Anti-Icing
Why do workers spray liquid onto the roadways before a big storm arrives? If you live in Idaho, you’ve probably asked yourself that question. It may seem dangerous to add liquid to a road that might freeze, but that liquid can be your best friend when winter driving conditions are at their worst. That liquid can prevent snow from sticking to the road and prevent frost or black ice. It’s one of the newest weapons against icy roads. Thanks to anti-icing, winter driving can be a safer experience. The following commonly-asked questions and answers will help you learn more about liquid anti-icing and the benefits it can offer motorists.
What is Anti-Icing?
Liquid anti-icers work like anti-freeze by lowering the freezing temperature of water and preventing ice from forming a strong bond to the road. They help keep roads from becoming slick, improve safety and reduce accidents.
Is it safe?
Anti-icing liquids are less toxic than baking soda or salt. Unlike sand, it won’t crack your windshield or chip your car’s paint. Tests have shown that the proper application of anti-icing liquids produces no negative effects on ground water, surface water or vegetation.
What can I do if I drive on roads where Anti-Icing liquids are used?
Wash your car on a regular basis. Anti-icing liquids (along with slush and dirt from the roads) can splash onto your car and build up after time, leaving a filmy residue on your car. Make car washing part of your regular maintenance routine, and you’ll help keep residue from the winter roads off of your car.
Why not use sand?
In many cases anti-icing liquids work better than sand. They keep snow from firmly sticking to the pavement. Anti-Icing liquids also last longer than sand and work in a broader range of conditions. Sand can be crushed by traffic and produce airborne dust, which contributes to pollution. Because sand is easily blown off the road by traffic, it requires repeated applications.
How are Anti-Icing liquids used?
Anti-icing: A light application of the liquid is made to a road before a storm to prevent a hard bond of ice, reduce snow buildup and speed snow and ice breakup after the storm.
De-icing: The liquid is applied to remove a thin layer of snowpack or ice already on the road. It can be very effective for melting black ice and freezing rain.
Pre-wetting: Wetting traditional sanding material with anti-Icing causes sand to stick to snowpack better. Keeping sand on the road is nearly impossible in some circumstances, especially in very cold weather and in cases where there’s traffic at highway speeds. Anti-Icing liquids can keep the sand from blowing to the shoulder of the road.
What about cost?
Anti-icing liquids are usually the most cost-effective alternative when considering the whole picture. There are less expensive chemicals to use for snow and ice control, such as salt and other ice melting chemicals. But those alternatives can be harmful to vehicles, bridges and the environment.
Anti-icing liquids are a good alternative because they are less corrosive and work better than other chemicals. They reduce environmental impact, bridge corrosion and vehicle damage.
In the last few years Idaho has worked with Montana, Washington, Oregon, Colorado and British Columbia to develop higher standards for a winter maintenance chemicals. The goal among the six transportation regions is to use a winter maintenance chemical that is appropriate for our environment and less corrosive than other alternatives.

Studded snow tires are legal in Idaho from Oct. 1 to April 30
Snowstorms may not be part of the immediate weather forecast, but Oct. 1 marks the date for legal use of studded snow tires in Idaho.
While it may be legal to use the tires, officials advise against it unless conditions warrant. Studded tires are snow tires with small metal cleats embedded in the tread, and may cause undue wear on bare roadways. Idaho’s studded snow tire season continues through April 30.
Studded tire laws vary in neighboring states:
- Montana: Oct. 1 – May 31
- Nevada: Oct. 1 – April 30
- Utah: Oct. 15 – April 15
- Oregon: Nov. 1 – March 31
- Washington: Nov. 1 – March 31
- Wyoming: Legal all year

Noxious weeds are spreading at an alarming rate across the Western United States. Each year approximately $23 billion is lost nationwide due to invasive plant impacts to agriculture, industry, recreation, and the environment. In addition, invasive plants are invading about 4,600 acres of land daily with over 8 million acres of Idaho lands severely infested by one of the 35 state-designated noxious weeds.
ITD Integrated Vegetative Management (IVM) program applies specific guidelines and complies with federal, state and local noxious weed laws to effectively eliminate, control and manage the spread of noxious weeds.
ITD is currently using environmentally beneficial landscaping which includes utilizing techniques that compliment and enhance the local environment and seek to minimize the adverse effects that landscaping has on it. It also provides a framework for preventing the introduction of and controlling the spread of invasive plant species on highway rights-of-way.
Some of these techniques and equipment include selective herbicide applications, brush control or removal, promoting native or adaptable vegetation, reseeding disturbed areas, bio-control agents and delivery systems, more efficient equipment cleaners, improved seeding equipment (for steep slopes), Global Positioning System (GPS) for invasive population inventories, and methods to minimize soil disturbance during vegetation management activities.

Wildflowers and other native plants provide visual character that enhances the natural scenic beauty of our state’s landscape. The growing concern for our natural heritage has generated an increasing interest in their restoration, preservation, and appreciation.
Our highways provide access to the splendors of nature as well as offer opportunities for natural beauty within their rights-of-way. The “Operation Wildflower” program and the Surface Transportation and Uniform Relocation Assistance Act of 1987 (STURAA) initiated the use of native wildflowers and other native vegetation along the rights-of-way to add natural character and diversity to the highway environment. These programs are the framework of Idaho Transportation Department’s wildflower and native habitat restoration programs.
Since 2001, ITD’s native plant program has reintroduced native species to thousands of road miles and incorporated native species into seed mixes and revegetation activities. Using native plants enhances biodiversity, preserves natural habitats, and restores native wildlife habitats.
Transportation planning and project development must reflect the desires of communities, and take into account the impacts on both the natural and human environments. Transportation projects are closely looked at to see how they might impact the community, the natural environment, and our health and welfare.

ITD supports research, development, and technology transfer activities addressing the Department’s strategic goals and initiatives. It is ITD’s mission to develop and maintain effective partnerships, deliver efficient and effective transportation services, offer practical solutions for immediate and long-term problems, develop new tools/technologies and facilitate their implementation, and coordinate projects performed by universities and agencies.
Roadside research focuses on balancing concerns for natural habitats and environments while enhancing roadside vegetation communities. It is a comprehensive program that focuses on improving the quality of natural environment by reducing noxious and invasive species establishment and spread, reducing wind and soil erosion, improving slope stability, establishing sustainable native vegetation, restoring natural habitats, and protecting and enhancing ecosystems. Research initiatives support statewide planning and involvement with the environmental process, construction activities, and maintenance operations.
Partnerships are essential to an efficient and effective integrated roadside vegetation program. Partnership projects help reduce soil erosion, increase wildlife habitat, and reduce damages caused by invasive species, wildland fires and other natural disasters. Public benefits include enhanced natural resources that help sustain environmental quality while supporting continued economic development, recreation, and natural beauty.
Bureau of Land Management
The I-84 Hazardous Fuels project was initiated between the Bureau of Land Management (BLM) and Idaho Transportation Department (ITD) in 2005 to implement fire management approaches to reduce the impact of devastating wildfires that have plagued the western U.S. for many years. The objective of the project is to increase public safety, improve the condition of natural resources on public lands by decreasing the number of fire starts originating from the I-84 transportation corridor, and decrease the spread and frequency of fires moving from the interstate onto adjacent public lands and into urban communities and sprawling home development.
Tri-State Cooperative Weed Management
The Tri-State project was initiated between WSDOT, MDOT, & ITD in 2006 to evaluate and implement noxious weed management strategies along the I-90 corridor stretching from Washington to Montana. The objective of the project is to implement a weed management plan and strategy for notifying agencies of new invaders, reduce economical impacts of new invaders, identify and stop the spread of new invaders across borders, educate the public and stakeholders on prevention and response measures, and increase awareness and communication.
