You are driving in the right lane of an interstate. Ahead, a car is speeding up in the acceleration lane to merge. The left lane next to you is clear. What should you do?
A travels in the right lane of an interstate while B accelerates ahead in the entrance lane. The lane to A’s left is empty, and no response is selected before the answer.
Correct answer: Move into the clear left lane, or adjust your speed, so that the car has room to merge.
Why
A merge works best when both drivers help. The entering driver must yield, but drivers already on the highway can prevent a conflict when they leave space. A space cushion to your sides also gives you room to move if the merging driver makes a mistake.
