Freeways & High-Speed RoadsStandalone practice
You are on an on-ramp that joins an interstate where traffic is moving at about 75 mph. How should you merge?
A travels along an entrance lane beside traffic on the main roadway.
Correct answer: Use the ramp to reach the speed of traffic, signal, check your mirror and blind spot, and merge
Why
High-speed roads usually have ramps so you can build up speed before you join traffic. Vehicles moving in the same direction at the same speed seldom collide, so matching the speed of traffic is the key to a safe merge. Signal, check your mirror, and turn your head to check the blind spot before you move into the lane.
