You must yield for emergency vehicles:
- Under no circumstances.
- When you see a flashing red or blue light or hear a siren. ✓
- Only when other vehicles yield.
- None of the above.
Answer: B. When you see a flashing red or blue light or hear a siren.
You must yield for emergency vehicles when you see a flashing red or blue light or hear a siren.
Why this is the answer
The handbook says drivers, bicyclists, and pedestrians must give the right-of-way to law enforcement vehicles, fire engines, and other emergency vehicles that are using sirens or flashing lights. When one approaches, you pull to the closest edge of the road right away and stop until it has gone by, and you keep intersections clear. The red or blue flashing light or the siren is the signal that the vehicle is on an emergency run and that the yield rule applies.
Why the other answers are wrong
- A. Under no circumstances. — This is wrong because the handbook requires you to yield to emergency vehicles using sirens or flashing lights, so there are clearly times when you must give way.
- C. Only when other vehicles yield. — This is wrong because your duty to yield depends on the emergency vehicle's lights or siren, not on whether the drivers around you decide to yield.
- D. None of the above. — This is wrong because the handbook does give a clear rule: yield when an emergency vehicle is using a siren or flashing lights.
Remember it
Light or siren means pull to the nearest edge and stop, and don't block the intersection.
