Traffic on the interstate moves at about 70 mph. You enter the acceleration lane at 40 mph, and there is a long, safe gap in the right lane beside you. What should you do?
A enters an acceleration lane at 40 mph next to interstate traffic traveling about 70 mph. A long clear gap is available in the right lane.
Correct answer: Speed up in the acceleration lane to near 70 mph, then merge into the gap
Why
Many crashes on multilane roads happen when one vehicle moves much faster or slower than the others. The acceleration lane lets you match the flow of traffic, so that a gap stays a gap when you move into it. Signal, check your mirrors and blind spot, and remember that traffic already on the interstate has the right-of-way.
