North Dakota car: Practice 6

You can see the main body of a snowplow, but blowing snow hides its side. Why should you leave generous lateral clearance?

Correct answer: A wing blade may extend beyond the visible body of the truck.

Plow wings can project several feet beyond the truck and be obscured by snow. Do not judge the machine’s clearance solely from the part of the body you can see.

Snow has piled around the rear of your stranded car. Before running the engine briefly for warmth, what must you check?

Correct answer: That the exhaust is working and its outlet is not blocked by snow.

A blocked exhaust can allow dangerous carbon monoxide to build up. Check the exhaust before using the engine for heat, and do not assume an idling vehicle is safe with a snow-blocked outlet.

You are choosing where to store blankets, water and a flashlight for winter emergencies. Why might the back seat be better than the trunk?

Correct answer: The supplies remain reachable if the trunk jams or freezes shut.

WisDOT suggests considering accessible storage because a trunk may be jammed or frozen. This is preparedness guidance, not a legal requirement to carry a particular kit. Secure supplies so they do not become hazards.
