Mastering winter roads: Guidance from the NWS for safe winter travel
Winter’s icy grip often turns roads treacherous, leading to over 6,000 weather-related vehicle fatalities and more than 480,000 injuries each year. When you find yourself on snowy or freezing rain-slicked roads, your top priority should be safety. Slow down and exercise caution. In temperatures near freezing, it’s prudent to assume icy patches on the road and adjust your driving accordingly. Be on alert for ice accumulating on power lines and tree branches, as they may break and fall. If possible, avoid driving in these conditions altogether. But if you must venture out, choose routes with fewer trees and power lines, and never touch a downed power line. If you encounter one, dial 911 immediately. Here are additional winter weather driving tips:
Share your travel plans:
When traveling out of town in hazardous winter weather, inform your family or friends of your destination, planned route, and estimated time of arrival.
Prepare your vehicle:
Ensure your gas tank is full and equip your vehicle with essential winter supplies such as a windshield scraper, jumper cables, a small shovel, flashlight, cell phone, blanket, extra warm clothing, drinking water, and high-calorie non-perishable food.
Stay calm when stranded:
If you become stranded, remain composed. Inform someone about your situation and location. Avoid attempting to walk to safety. Indicate that you need assistance by attaching a cloth to your car’s antenna or mirror, and make your vehicle more visible by using the dome light and flashers
Be aware of snow plows:
Keep an eye out for snow plows and allow them ample room to pass. Only overtake a plow when you have a clear view of the road ahead.
Check road conditions:
Before embarking on your journey, verify the current road conditions to make informed travel decisions.
