When it is this cold, it ‘s almost a must to start your car to warm it up, but how long should you leave it on before driving it.

Coordinator of Earthcare Sudbury Initiatives, Jennifer Babin-Fenske says two minutes is plenty of time.

Babin-Fenske says you probably won’t be charged if you are leaving your car on for a long period of time to warm up, but just remember that it is unnecessary.
