Use the 3-second rule to keep a safe distance

Tap each step as you finish it.

1. 1Pick a fixed object ahead, like a sign or a tree.
2. 2When the car in front passes it, start counting: one thousand one, one thousand two, one thousand three.
3. 3If you reach the object before you finish counting, you're too close. Back off.
4. 4In rain, snow or at night, leave even more time.
