Alaska DMV Permit Practice Test 1
THE "THREE-SECOND RULE" APPLIES TO THE SPACE _________ OF YOUR VEHICLE.
Most rear end collisions are caused by tailgating. To avoid tailgating, use the “three-second rule”: when the vehicle ahead of you passes a certain point such as a sign, count “one-thousand-one, one-thousand-two, one-thousand-three.” Counting these numbers takes approximately three seconds. If you pass the same point before you finish counting, you are following too closely.
