‘The Salt Seeing Eye:’ the snowplow driver’s crystal ball

A hand points out the screens inside the cab of a snowplow, one of which shows the truck bed holding salt.

If we each had a crystal ball, just think of all the time, money, pain or heartache we could save!

While not exactly a crystal ball, Idaho Transportation Department plow operator Skylerr Valentine, with help from the Idaho Falls shed crew, has come up with an innovation that’s a little bit close. Well, for ITD operations folks in terms of work that is.

Valentine pondered on the fact that while plowing, he would need to make multiple stops through his route to climb up the truck bed and see how much salt was left. This of course involved pulling over, getting out of the cab and physically climbing on the heavy equipment. On newer dump/ plow trucks, a small ladder is fitted to the side of the bed. On older ones that still operate in force across the state, this salt check involves navigating from the stairs of the cab across to one of the rims of the truck bed. Valentine actually once fell while doing just that.

He figured that surely a camera could be installed to show down into the sander box that holds augers and salt. This would allow salt levels to be monitored visually just like wing plows are. He happened to be aware of a truck in east Idaho that was on the surplus sale line and talked to ITD Fleet Manager Dalton Rice about using the outdated wing plow camera from it to test out this innovative idea.

With the help of the entire Idaho Falls crew and ITD electricians Josh Harris and Justin Romrell, that older camera was mounted to the truck bed and wired around, then into the cab, with concern for easy disconnect points to retain dump truck functionality. The smaller screen of the unit was mounted inside, just underneath the tablet typically used by plow operators. Valentine dubbed it the “Salt Seeing Eye.”

“It was a lot of work, figuring it all out just right,” he said. “We really tried to make sure it was waterproof and could stand up to the elements. I wanted to see it put to the test this winter.”

Tablets equipped inside plow trucks show drivers video of where their wing is at, and relay salt and brine output numbers right on the screen. They don’t, however, indicate when salt in the truck bed is gone. Those numbers keep on ticking, and the operator keeps on driving, thinking he’s covering the road when in fact, he’s sure not.

Multiple times Valentine, and surely other operators anywhere, would stop to check salt levels in the bed, only to see that it’s empty and have no idea how long it had been. Then begins backtracking to determine where to pick back up with salt application, essentially doing the same thing over again and wasting time.

“I would make a 70-mile round trip, having run out but no idea where,” Valentine said. “I had no idea how long ago it had been or how many miles really had nothing on the road.”

There are formulas and historical knowledge that can help operators determine just how far so much salt will cover. Let it be said that ITD operations folks could certainly be given science and math degrees for the calculations they’ve mastered when it comes to doing the work they do. They rely on the output readings on the tablet in each truck also. Where those reading don’t stop even if the salt is empty, calibrations aren’t without a significant margin of error though.

“This could really help us find discrepancies in our calibrations,” Idaho Falls Operations Foreman Jared Loosli said. “It has the potential to save a lot of money when it comes to salt ordering.”

This winter, Valentine has indeed had the chance to put the new tool to the test. While plowing the five-lane section of US-20 west of Idaho Falls, he’s determined from the safety of the cab that he can in fact make one more pass on his route, where he normally would have stopped to check or headed back to the shed to refill.

The “Salt Seeing Eye” may not be the crystal ball that can help any one of us avoid bad personal life decisions, unfortunately. But with substantial time saved while snowplows are out doing the vital work they do, increased safety for operators that would no longer have to climb on heavy equipment in slick winter conditions, and visible cost savings through more accurate salt use calculations, this innovation certainly has the potential to greatly benefit operations across Idaho.

Ideally, this camera could come standard on all new ITD trucks and be paired with the typical tablet, becoming one of the options right on the screen operators use now.

ITD is on the job plowing snow: Here’s what you should know

Snowplow on SH-28 plowing snow and creating a plume to the side.

With snowy conditions foreseeably here to stay, the Idaho Transportation Department is committed to keeping motorists safe. In eastern Idaho, maintenance crews are now working around the clock shifts from the Utah to Montana state lines as needed.

These 17 crews across eastern Idaho keep more than 4,300 lane miles of state highways and interstates as clear as possible all winter long. Plowing that amount of roadway means patience and caution from the public are important.

“We have high confidence in our plow teams,” ITD Operations Engineer Jeremie Pettingill said. “Winter driving does take some planning though. Slow down and be aware. Know that we’re prepared and doing the very best we can.”

ITD aims to keep roads bare 70% of the time during storms. The wind conditions in east Idaho often make that unrealistic and are the primary cause of road closures through the winter.

Closures are put in place only when conditions are unsafe. Roads are also only closed as long as necessary. Closures allow operators to be more efficient getting snow cleaned up, braving the elements as they do.

ITD reminds motorists across east Idaho to use common safe winter driving practices:

Brush and scrape your windows before driving. Starting the defrost in your vehicle well before you leave is very helpful.
Slow way down! Speed limits are based on ideal conditions and aren’t appropriate during winter weather.
Maintain substantial distance between yourself and other drivers—don’t follow closely.
Stay calm and don’t make sudden wheel movements in icy conditions.
Don’t use cruise control in the winter.
Obey posted road closure signs and lights—finding a back way to access closed roads is dangerous and delays plow work to get them re-opened! Remember roads are only closed for good reason. Unexpected traffic and crashes significantly delay getting the road re-opened.
Keep a winter emergency kit in your vehicle with supplies like water, lights, warm clothes and blankets, etc.
When you see plows, give them room to work. That means leaving plenty of following distance, not crowding them and letting them lead the way. Last winter, 17 plow strike occurred across Idaho, most often due to drivers attempting to pass.
Know before you go by checking conditions at 511.idaho.gov or on the Idaho 511 app. Cameras can show you exactly what to expect on certain roadways, and conditions are updated multiple times a day.

Extreme Cold May Result in Additional Road Closures

RIGBY – As extreme cold continues in East Idaho, the Idaho Transportation Department is asking motorists to plan ahead and check the 511.idaho.gov website before hitting the roads. “It’s vitally important that drivers are paying close attention to current conditions,” said ITD Public Information Officer Justin Smith. “We always try to keep roads open, but when conditions become unsafe for our plow drivers we have to close the roads to protect everyone.”

Smith also noted that drivers checking the 511 website or using the newly updated version of the 511 app might see a webcam of one portion of the road that looks fine, but other sections may not be safe. “With the changes in altitude at places like the Ashton Hill conditions can be vastly different from Idaho Falls or Henry’s Lake.”

Those changing conditions can also be dangerous. The National Weather Service announced over the weekend that wind chills are dropping to -15°F to -40°F. At -30°F exposed skin can freeze in as little as 10 minutes. That means motorists must be sure to have their vehicle serviced. A poorly maintained vehicle can leave someone stranded.

AAA notes (https://exchange.aaa.com/safety/driving-advice/winter-driving-tips/) several other precautions motorists should take:

Keep a bundle of cold-weather gear in your car, such as extra food and water, warm clothing (including additional clothing for every passenger), a flashlight, a glass scraper, blankets, medications, and more.
Make certain your tires are properly inflated and have plenty of tread.
Keep at least half a tank of fuel in your vehicle at all times.
Never warm up a vehicle in an enclosed area, such as a garage.
Do not use cruise control when driving on any slippery surface, such as on ice and snow.
Stay home and only go out if necessary. Even if you can drive well in bad weather, it’s better to avoid taking unnecessary risks by venturing out.

It is especially important to consider children, the disabled, and elderly who may be passengers. “Sometimes we forget that children and vulnerable adults do not have the ability to maintain body temperature. Kids like to go out without enough cold weather protection, but parents should ensure there are coats, hats, gloves, and other necessities are available if needed,” Smith said.

This winter has become more challenging as District 6 has lost a number of plow drivers leaving 17 vacant positions open. “We do have a few relief plow drivers to help with the vacancies, but it’s not enough to take the pressure off,” said Bryan Young. “This number includes employees who are retiring or are out for extended health reasons. We do have a few new hires, but they will not be 100% this winter.”

The vacant positions may make it necessary to close roads sooner than motorists may be used to. When fully staffed multiple plow drivers can work the same highway from both directions. However, with fewer plows on the road it may not be possible to keep a road open. This is especially the case where snowfall is heavy and strong winds are blowing.

ITD has also been dealing with numerous plow strikes and drivers making dangerous maneuvers around plows. So far 13 plows have been hit this season. Most of those incidents were related to drivers going too fast for conditions and passing plows on the right.

Drivers need to be careful in upcoming storm

RIGBY – With a severe winter storm predicted by the National Weather Service (https://www.weather.gov/pih/), the Idaho Transportation Department in East Idaho reminds drivers to take precautions in case roads close or motorists become stranded. Extreme cold temperatures, snow, and wind can make for a dangerous combination.

“We do everything we can to keep roads open,” said Bryan Young, D6 Operations Engineer. “However, we also have to consider the safety of the traveling public and our crews.”

ITD asks the public to think ahead and determine whether a trip can be delayed or avoided during winter storms. Check 511.idaho.gov or the 511 app to learn if roads are closed and to view conditions. If you are driving, be careful to leave extra distance between vehicles, never pass a snowplow on the right, and pay close attention to changing conditions.

Other safety tips include:

Keep survival supplies in your vehicle: blankets, flashlight, water, and food.
Fill your vehicle’s gas tank before leaving.
Be sure your car is well-maintained with fluids at proper levels, tires properly inflated, wipers, brakes, and battery are all in good condition.
Dress appropriately for cold weather: heavy coat, boots, gloves, and have extra socks.
Prepare to self-rescue if your vehicle is stuck by having: a shovel, kitty litter, tire chains.
Inform others of when you are leaving, what route you are taking, and what time you expect to arrive.
Ensure your cell phone is charged before leaving.
If your vehicle becomes stuck, check to be sure the tail pipe is clear so exhaust fumes do not build up in the cabin.
Crack a window to avoid carbon monoxide build-up and only run your vehicle for 10 minutes per hour to keep the cabin warm.

Idaho Ready: What you need to know about the chain up law

In extreme winter weather, chains can be a helpful tool to keep you safe while driving on slushy or snow covered roads. But are they required in Idaho?

Idaho’s chain up law does not apply to most drivers on the road, or even most places you drive.

The law only applies to commercial vehicles over 26,000 pounds on mountain passes, most notably on I-90 east of Coeur d’Alene and on US-12 at the Montana border.

This can be confusing, as chain laws vary by state. Neighboring states, like Washington, may require passenger vehicles without AWD or four-wheel drive use chains during the harshest of conditions.

In Idaho, chains are only required when conditions will prevent large vehicles from traversing grades without them, and the requirement is lifted as soon as possible to limit damage to the road. Operators with the Idaho Transportation Department activate special roadside signs alerting truck drivers to chain up as needed during the winter.

Some commercial vehicles, like logging trucks, tow trucks, and school buses are exempt from the law.

If the chain up law is in effect, then all drivers should be prepared for snowy conditions. Stay on top of road conditions or closures by visiting 511.idaho.gov or downloading the Idaho 511 app.

Idaho Ready: Pack your winter car emergency kit

Winter weather has arrived in Idaho and it’s time to be Idaho Ready on the road. One way you can do that? Keep an emergency kit in your car this winter.

You want to be prepared for anything that comes your way, so here are a few things you should always have with you when traveling.

Flashlight — make sure the batteries work
Jumper cables — in case your car won’t start, or maybe you need to help someone else
Kitty litter can give you some traction if your tires are spinning on ice
Chains
Small shovel to dig out around your tires or tailpipe
Flares and a first aid kit
Food and water — pack high protein snacks that will fill you and your family up for a while
Anything to keep you warm — a blanket or a small sleeping bag, winter coat, gloves, hat, and waterproof boots
Ice scraper

If you run off the road, break down, or simply get stuck during a storm, these items will help keep you warm and safe until help arrives. Remember, always let someone know about your travel plans, especially if you’ll be driving through areas with no cell service. Check the latest road conditions at 511.idaho.gov before you leave.

Idaho Ready: Winter driving insight from ITD’s snow plow operators

In Idaho you have to be prepared for all sorts of winter weather, and that means being Idaho Ready to drive safely. The Idaho Transportation Department wants drivers to have the knowledge and resources to do that, before they hit the road. Read the messages below to gain some winter driving insight from ITD’s own snow plow operators.

It’s time to be Idaho Ready for winter driving

As winter weather arrives in Idaho, the Idaho Transportation Department has launched its annual winter safety campaign, “Idaho Ready.”

The campaign aims to help drivers prepare for challenging conditions on the state’s highways, offering tips and resources to stay safe before drivers hit the road. Short videos, blog posts, and photos will be posted weekly to Facebook, Twitter, YouTube, and online at itd.idaho.gov/travel.

So, are you Idaho Ready for winter driving? Here are a few tips to help you stay safe on the road.

First, check road conditions before you leave! Visit 511.idaho.gov or download the Idaho 511 app to look at weather reports and cameras across the state.

Be prepared. Keep an emergency kit with food, water, and a blanket in your car.

If roads are wet or icy, slow down and give yourself plenty of stopping room.

Pay attention to the outside temperature. When it’s near freezing, ice can form quickly, and when gaining elevation, wet roads can change to ice in just a few miles. Even when the temperature is above freezing, shaded roadways can be slick. Take it easy on overpasses and bridges too. These are the first to freeze when temperatures drop.

Snow tires and chains can help keep you moving, but be sure to practice installing your chains so you know how to use them.

When roads are slick, turn your cruise control off. If you start to slide, regain control by taking your foot off the gas and slowly turning your wheel in the direction of the skid. Try not to overcorrect, and do not slam on the brakes.

If you encounter a snow plow, slow down and make room. The safest place is behind the plow. Never pass on the right.

Please wear your seatbelt, stay engaged, and drive for the conditions. Be sure to follow along online with ITD this winter so you are always Idaho Ready.

Before you go, don’t forget to pack your winter car emergency kit

Of the many things that Idahoans know a lot about, one of them is how to be prepared. Prepared for the big game, prepared for the campout, and prepared for the road. Whether you’ve lived in Idaho your whole life or are a new resident, it’s important to do everything you can to prepare for an Idaho winter. As the cold weather sets in, so do winter road conditions.

So how do you prepare for Idaho winter travel? We recommend starting by calling or visiting 511.idaho.gov to check road conditions and alerting friends and family of your travel plans (especially if you are traveling through areas with poor cellular service). Take time to review a map and make sure you know your path of travel as opposed to relying solely on GPS navigation which can occasionally be incorrect. Once you’ve checked those things off your list, ensure you are prepared for whatever comes your way by packing a winter car emergency kit.

Keeping a winter car emergency kit on hand won’t just benefit you, but it could come in handy for others you come across while traveling. Here are some items we recommend you include when building your winter car emergency kit:

Flashlight with extra batteries to use as a light source and signal for help.
Jumper cables to jump your own vehicle or assist other motorists.
Tire pressure gauge to ensure you are driving with the optimum inflation.
Cat litter to use as traction on slick surfaces.
Small camping shovel to assist with removing snow around tires and tailpipes.
LED flares to alert motorists of a broken down vehicle or roadway obstruction.
First Aid Kit for minor injuries and emergencies.
High protein food and bottled water to keep you hydrated and give you energy should you be stuck for a period of time. If your food items are in cans, make sure you also have necessary items like a can opener and utensils in your kit as well.
Winter coats and gear such as hats, gloves, etc. to help keep your body temperature up.
Blanket or a small sleeping bag for warmth in freezing conditions.

Some of the items may seem excessive but if you run off the road, breakdown or simply get stranded during an extreme storm, these items will help keep you warm and safe until roadside or emergency services are able to reach you.

For those that already have a winter car emergency kit in a vehicle, make sure you do an annual check of items to ensure they are in good condition and working order – remember, food expires and batteries don’t hold their charge forever. Also, if you do find yourself stuck in the snow, don’t run your vehicle without first ensuring the tailpipe and up to three feet behind your vehicle is free of snow; this, along with opening your windows, will prevent deadly carbon monoxide from building up inside the automobile.

As a parting note, be sure to replace worn windshield wipers, keep gas in your car and have the proper tires on before driving in winter weather conditions. Keeping all of that in mind, you’ll be well on your way to being prepared for an Idaho winter.

Looking back on a historic, record-setting winter

The 2016/2017 winter and spring across Idaho will likely be remembered for its intensity on all fronts-from snow to floods to the damage left in its wake. In this edition of ITD in Motion, Jennifer Gonzalez talked to our crews on the front line about their experiences battling every challenge Mother Nature has thrown our way.
