When you are merging onto the freeway, you should be driving:
- At or near the speed of traffic on the freeway. ✓
- Five to 10 mph slower than the speed of traffic on the freeway.
- The posted speed limit for freeway traffic.
Answer: A. At or near the speed of traffic on the freeway.
When merging onto the freeway, drive at or near the speed of traffic so you can join the flow safely.
Why this is the answer
The handbook's freeway-entry steps say to be in the proper on-ramp lane and be at or near the speed of traffic. It also says to merge when safe, not to stop unless absolutely necessary, and to choose a space large enough for your vehicle. Matching the traffic flow is what lets you fit into that space. The handbook does not tell you to enter several miles per hour below traffic or to treat the posted limit as the target when traffic is moving at a different speed.
Why the other answers are wrong
- B. Five to 10 mph slower than the speed of traffic on the freeway. — Driving five to 10 mph below the traffic flow is not what the handbook instructs; it says to be at or near the speed of traffic when entering.
- C. The posted speed limit for freeway traffic. — The posted speed limit is not the same instruction as matching traffic; the handbook tells you to be at or near the speed of the traffic already on the freeway.
Remember it
On the ramp, aim to match the cars you plan to join.
