A driver traveling on the frontage road of a controlled-access highway must yield the right-of-way to a vehicle:
- Entering or about to enter the frontage road from the highway.
- Leaving or about to leave the frontage road to enter the highway.
- Both of the above. ✓
- None of the above.
Answer: C. Both of the above.
The driver must yield in both situations, so the correct choice is that both entering the frontage road from the highway and leaving it to enter the highway require a yield.
Why this is the answer
The handbook lists two situations at a controlled-access highway frontage road, and both require the frontage-road driver to give way. One is a vehicle coming from the highway and entering the frontage road, or getting ready to do so. The other is a vehicle leaving the frontage road to go onto the highway, or preparing to leave. Because the rule covers both directions of movement between the frontage road and the highway, the choice that says both situations is the correct one.
Why the other answers are wrong
- A. Entering or about to enter the frontage road from the highway. — This covers only the vehicle coming from the highway onto the frontage road, while the handbook also requires yielding to a vehicle leaving the frontage road for the highway.
- B. Leaving or about to leave the frontage road to enter the highway. — This covers only the vehicle leaving the frontage road for the highway, while the handbook also requires yielding to a vehicle entering the frontage road from the highway.
- D. None of the above. — The handbook does not say no yield is required; it specifically lists both the entering and leaving situations as times the frontage-road driver must yield.
Remember it
Picture the frontage-road connection as a two-way yield point: watch for cars coming off the highway and cars heading onto it.
