To enter a freeway:
- Signal, yield to existing traffic, and enter at the same speed that traffic is moving. ✓
- Signal and enter the freeway. Freeway traffic must yield.
- Drive slowly so you can check traffic.
- Always come to a complete stop first.
Answer: A. Signal, yield to existing traffic, and enter at the same speed that traffic is moving.
To enter a freeway, signal, yield to the traffic already on the highway, and build up speed so you merge at the same speed traffic is moving.
Why this is the answer
The handbook describes entering a limited access highway in steps: on the entrance ramp you check for a gap and signal, then use the acceleration lane to gain speed and adjust it so you can merge safely when the lane ends. It states plainly that you must yield the right-of-way to traffic on the highway, and it warns against stopping in the acceleration lane unless traffic is too heavy to enter safely. Yielding while matching highway speed fits those steps.
Why the other answers are wrong
- B. Signal and enter the freeway. Freeway traffic must yield. — Freeway traffic already on the highway has the right-of-way, so signaling does not make other drivers yield to you.
- C. Drive slowly so you can check traffic. — The handbook says to increase speed on the ramp and acceleration lane, and creeping slowly leaves you far below the speed of traffic you are trying to merge with.
- D. Always come to a complete stop first. — Stopping is only acceptable in the acceleration lane when traffic is too heavy and there is no safe space, so a complete stop is not the normal first step.
Remember it
Think ramp, then acceleration lane, then merge: signal early, pick your gap, and be going highway speed when the lane runs out.
