You are on a freeway entrance ramp. Traffic in the right lane of the freeway is heavy, and you do not see a gap yet. What should you do?
A is on the freeway entrance ramp, before the longer acceleration lane. Several vehicles occupy the freeway’s right lane without a usable entry gap.
Correct answer: Slow down on the ramp, so you still have room to speed up in the acceleration lane when a gap opens.
Why
An acceleration lane gives you room to reach the speed of freeway traffic before you merge. Look for a gap early, signal, and adjust your speed in the lane so that you enter at the same speed as the traffic. A stop at the end of the lane is dangerous for you and for the drivers behind you, who watch the freeway traffic and do not expect you to stop.
