Weather, Visibility & EmergenciesStandalone practice
You are stranded in snow and waiting safely inside your car. What precaution is important before running the engine briefly for warmth?
Correct answer: Clear the tailpipe and open a window slightly.
Why
The handbook advises staying with the vehicle, running the engine only briefly, and opening a window for ventilation. Make sure the tailpipe is free of snow and debris if you can check safely. Exhaust fumes contain deadly carbon monoxide; stop running the engine if you cannot keep the exhaust safely clear.
