Driving in Rain, at Night, and in Heavy Traffic

Rain and Night: The Golden Rule

If you can't see the car behind you clearly in your mirrors, do NOT change lanes.

Before every lane change in rain or darkness:

• Confirm mirror visibility. If rain or fog has obscured your mirrors, fix that first — defroster, wipers, heated mirrors.
• Check blind spots twice. Not once. Twice.
• Know how to use your defogger and heated mirrors before you need them. Fumbling with buttons at 60 mph means you've already lost.
