Four vehicles approach a signalized intersection under the operational conditions described below. Arrange these vehicles in the correct order of right-of-way precedence, from the vehicle that has the highest priority to proceed first (position 1) to the vehicle that must yield to all others (position 4).
- 1An emergency response vehicle approaching from the cross street with active flashing lights and siren.
- 2A vehicle turning right on a solid green light.
- 3A vehicle making an unprotected left turn on a solid green light.
- 4A vehicle executing a U-turn from the opposite direction on a solid green light.
Answer
The correct order of right-of-way precedence from first to proceed to last is: (1) Emergency response vehicle with active sirens and lights, (2) Vehicle turning right on a solid green light, (3) Vehicle making an unprotected left turn on a solid green light, and (4) Vehicle executing a U-turn on a solid green light.
Emergency vehicles operating with active warning equipment take highest priority. Among standard vehicles facing a solid green light, right-turning vehicles proceed before unprotected left turns, while U-turning vehicles must yield to all oncoming traffic.
