Even if you live where snow never falls conditions can change rapidly. Just the thought of driving in the snow makes me nervous. I had few chances to drive in the snow previous to my move here, and those experiences were not encouraging. I was extremely lucky in that I never hit another car, but it still left me shaken up and scared to drive. Don't let cold temperatures tempt you into starting your car in a closed garage.
Carbon monoxide can be fatal when breathed in a confined area.
Slow down on bridges and overpasses, which freeze first. Avoid sudden changes of speed or direction as you drive over them. Look out for other danger zones while driving, like intersections, hills and curves. Reduce speed and watch for other drivers that may be skidding. Keep windows free of snow and ice.
