A driver entering interstate traffic from an entrance or acceleration ramp:

1. Should yield to drivers already on the interstate. ✓
2. Has the right-of-way.
3. May force their way into traffic.
4. Can assume that other drivers will change lanes to make room.

Answer: A. Should yield to drivers already on the interstate.

You should yield to drivers already on the interstate when you enter from an entrance or acceleration ramp.

Why this is the answer

The Texas handbook tells a driver entering a highway to give the right-of-way to vehicles already on it. It then describes the merge: use the speed change lane, stay to the right, signal left, and when traffic is clear, raise your speed to join the flow. That sequence puts the responsibility on the entering driver to adjust speed and wait for a safe gap, not on interstate traffic to move over or slow down.

Why the other answers are wrong

• B. Has the right-of-way. — Drivers already on the interstate have the right-of-way, so the entering driver does not.
• C. May force their way into traffic. — The handbook directs the entering driver to wait until it is clear; forcing a way into traffic is the opposite of yielding.
• D. Can assume that other drivers will change lanes to make room. — Nothing in the handbook says other drivers will change lanes; the entering driver must yield and merge only when clear.

Remember it

Ramp rule: they keep the lane, you find the gap.
