Drivers turning left must yield to:
- Overtaking cars.
- Oncoming cars. ✓
- No one.
Answer: B. Oncoming cars.
Drivers turning left must yield to oncoming cars.
Why this is the answer
The handbook's rule for a flashing yellow arrow covers this: you may turn left, but the turn is not protected from other traffic, so you go after yielding to oncoming traffic and with caution. It also warns that turning your wheels left too early can push you into oncoming traffic if hit from behind. Together these passages point to oncoming cars as the traffic a left-turning driver must yield to.
Why the other answers are wrong
- A. Overtaking cars. — The handbook does not make overtaking cars the group you yield to on an unprotected left turn; it specifically says to yield to oncoming traffic.
- C. No one. — This is wrong because a flashing yellow left-turn arrow still requires you to yield to oncoming traffic before turning.
Remember it
Picture the flashing yellow arrow: your left turn is not protected, so let the oncoming cars clear first.
