Winter Driving And Missouri Laws


Winter weather calls for drivers to make adjustments! The Missouri State Highway Patrol encourages motorists to plan ahead and drive safely or not at all during inclement weather.

Drivers: Take the time to clean snow and ice completely from your vehicle. Allow extra driving time for you to reach your destination at a slow, safe speed. Make sure the windows are completely cleared to ensure visibility. Remember: Missouri law Section 307.020 RSMo, states if you’re using your windshield wipers, your headlights must be turned on. It takes only a second to turn on your vehicle’s headlights. That second could make you more visible to other drivers and prevent a traffic crash.

Also keep in mind that Section 307.020 RSMo. states lighted lamps are required "from a half-hour after sunset to a half-hour before sunrise and at any other time when there is not sufficient light to render clearly discernible persons and vehicles on the highway at a distance of 500 feet ahead."

When inclement weather hits, please adjust how you drive so that you continue to "exercise the highest degree of care". For instance: Stopping quickly in the winter on snow-covered or icy roads is next to impossible. Use care by increasing your following distance as you drive. Increase your following distance to five seconds or more. Section 304.012 RSMo. directs motorists to exercise the highest degree of care on Missouri's roadways. This part of Missouri law states, "Every person operating a motor vehicle on the roads and highways of this state shall drive the vehicle in a careful and prudent manner and at a rate of speed so as not to endanger the property of another or the life or limb of any person and shall exercise the highest degree of care."

Ask yourself if the speed you're traveling is safe for the weather conditions. Slow down when driving in snow or on ice. Driving the speed limit may not be "exercising the highest degree of care" during inclement weather; driving over the speed limit never is.
