Show answer & explanationAnswer & explanation
Correct answer: D. Accelerate to match the speed of highway traffic while on the acceleration lane.
Matching the speed of highway traffic is crucial for a safe merge. This minimizes the speed differential between your vehicle and existing traffic, reducing the risk of collisions.
Why the other options are wrong
- A. Stopping on an acceleration lane is extremely dangerous and can cause rear-end collisions.
- B. Accelerating to the speed limit on the ramp might be too slow if highway traffic is faster, or too fast if the ramp is short.
- C. Slowing down before merging makes it harder to find a safe gap and can disrupt traffic flow.
