Drivers turning left must yield to:
- Oncoming vehicles traveling straight or turning right. ✓
- Passing cars.
- No one in particular.
Answer: A. Oncoming vehicles traveling straight or turning right.
When you turn left, you must yield to oncoming vehicles that are going straight or turning right.
Why this is the answer
The handbook's left-turn steps have you stop behind the limit line or before the crosswalk, then look both ways and begin only when it is safe. It also warns you not to swing the wheel early and drift into the lane of oncoming vehicles, and that where traffic goes straight through an intersection, that traffic holds the right-of-way. Put together, the driver crossing or turning right from the opposite direction gets to go before you complete your left turn.
Why the other answers are wrong
- B. Passing cars. — The handbook's left-turn instructions never give passing cars priority; they deal with pedestrians, vehicles already in the turn lane, and oncoming traffic.
- C. No one in particular. — The steps clearly require you to wait for a safe gap and warn that turning the wheel too soon can push you into oncoming traffic, so there is someone to yield to.
Remember it
Look left-right-left and hold your wheels straight until the oncoming lane is clear before you commit.
