Prior to starting your vehicle, first make sure that the exhaust pipe is not covered or encased with snow, even if the vehicle is unoccupied and you are just warming it up.
The very first action you should taking when digging out a vehicle is to clear away the snow from the tailpipe a distance of at least 3 feet and keep checking that it remains clear which you shovel out your car. Never let children sit in an idling car while shoveling. Clear snow from the exhaust pipe and leave the engine off until the car is ready to roll.
Reminder: Never warm up your car in the garage!
