Be sure to visit https://www.safetravelusa.com/sd/ or call 5-1-1 to check the latest road conditions and travel advisories before heading out. Travelers are also reminded that although conditions appear to be “OK” in one area, they can be and are likely worse in other areas along the same route.
If you must travel, the departments of Transportation and Public Safety recommend travelers also take the following steps.
Wear your seatbelt
Travel during the day
Drive with your headlights on (not daytime running lights) so you can be seen by other motorists from the front and rear
Don’t use cruise control on icy or snow-covered roads
Use highly traveled roads and highways
Keep family and friends informed of your travel schedule and route
Call 511 or visit safetravelusa.com for road conditions
Keep a winter weather survival kit in your car. The kit should include blankets, warm clothing, water, energy bars, a flashlight, a distress flag, a shovel, and matches
Travel with a charged cell phone, but don’t rely on it to get you out of a bad situation
Change travel plans as weather conditions warrant
If you do get stranded:
Stay in your vehicle
Run the engine and heater about 10 minutes an hour to stay warm
When the engine is running, open a window slightly to prevent carbon monoxide poisoning. Periodically clearing snow from the exhaust pipe will also help prevent carbon monoxide buildup
When it’s dark outside, turn on the interior light so rescuers can see you
Put up a distress flag, or spread a large colored cloth on the ground to attract attention from rescuers
