CDL Practice Question #85

A safe practice when entering a freeway is to:

Stop at the end of the on-ramp and wait
Use the entire on-ramp to accelerate to traffic speed and merge into a gap
Slow to 25 mph regardless of traffic
Force traffic to make space

Correct. Use the on-ramp to match traffic speed before merging. Stopping at the end of an on-ramp is dangerous.

Why this question matters

This question is one of 97 in our General Knowledge bank. The reasoning above comes directly from the AAMVA CDL Manual, the source document used by every U.S. state DMV. Memorizing the underlying rule — not just the letter answer — is what separates passing on the first attempt from a return trip and another fee.
