AMES, Iowa – Oct. 15, 2020 – With all the challenges in 2020, one thing has remained the same – the Iowa Department of Transportation’s focus on safely getting you where you need to go. With winter approaching, we’re getting ready for whatever may come for the rest of 2020 and into the new year.
How the Iowa DOT prepares for the winter travel season
We use a data-driven approach partnered with the experience of our winter operations staff to pack a strong one-two punch to any winter storm situation.
The department’s 101 maintenance garages employ 1,082 full-time equipment operators, mechanics, and supervisors, as well as around 600 temporary employees, hired each winter season, to keep the agency’s 902 trucks, 43 motor graders, 27 tow plows, and 11 heavy-duty, self-propelled snowblowers on the road during winter weather.
The Iowa DOT has spent the warmer months stocking salt in our storage facilities for use during the winter. Buying during the spring and summer allows us to obtain better pricing because demand is low. On average, the Iowa DOT uses more than 150,602 tons of salt and 31.5 million gallons of brine each year to help maintain safe travel on 9,500 miles of the primary highway system, consisting of the interstates, U.S., and Iowa routes.
The Iowa DOT primarily uses salt brine, a simple solution of standard rock salt and water, to help with winter roadway maintenance. It can be used to pretreat roadways before a storm, thus preventing snow and ice from sticking to the pavement. Brine is also used to prewet salt before it leaves the truck, increasing its ability to melt snow and ice and helps keep it on the roadway surface.
You may wonder why Iowa DOT trucks sometimes spray brine on sunny days. Frost is a major safety factor this time of year. The Iowa DOT’s proactive approach of spraying brine on areas prone to frost prevents the formation of an icy layer, which typically occurs on cold, clear nights. Frost is hard to see on the road’s surface and most people don’t expect it. These unexpected encounters with a frost-covered bridge or roadway can be particularly treacherous when traveling at higher rates of speed, making it more difficult to maintain control of your vehicle.
What you can do to prepare for the months ahead
Winterize your vehicle. To minimize the possibility of a breakdown, get your vehicle tuned up. Check your vehicle’s wipers, hoses, battery, alternator, belts, tires, brakes, exhaust system, lights, and fluid levels. Make sure your vehicle’s heater and defroster are in good working order and you travel with plenty of gas in your tank. A breakdown is frustrating on a good day but can be dangerous during wintery weather.
Place a winter survival kit in your vehicle. This kit should contain items to help sustain your life and the lives of your passengers should your vehicle become stranded during inclement weather. These items can include booster cables; a flashlight with fresh batteries; extra blankets and warm clothes; nonperishable, high-calorie food items; candles, matches, and a can for melting snow for drinking water; and a snow shovel. Sufficient supplies should be in the kit for all persons traveling in the vehicle. Carrying a mobile phone and charger in your vehicle is also advised for use during an emergency.
Time to kick your winter driving skills into gear
The first snowfall and slick roads are a quick reminder that it’s time to re-evaluate and adjust your driving behaviors.
- Wear your seat belt. Every trip, every time.
- Turn off the cruise control. Cruise control does not allow you to let off the accelerator if you hit a slick spot, making it more difficult to maintain control of your vehicle.
- Adjust your speed for conditions. Speed limits are set for ideal driving conditions. Winter weather can create hazards that require slower speeds. Remember these simple slogans, “Ice and Snow … Take It Slow” and “Don’t Crowd the Plow.”
- Take it easy. On slick pavements your driving maneuvers need to be gradual and smooth, so you do not skid or spin. Change lanes or turn with graceful movements, begin braking sooner gently increasing pressure on the pedal, and give yourself more room around other cars to allow for everyone’s reduced ability to stop or maneuver.
