Four vehicles approach a signalized intersection under different traffic and situational conditions. Based on standard right-of-way rules, in what order should these vehicles proceed through the intersection, from first (highest priority) to last (lowest priority)?
- 1An emergency ambulance approaching with active flashing lights and siren
- 2A sedan proceeding straight through the intersection on a solid green light
- 3A pickup truck making an unprotected left turn on a solid green light
- 4A compact car turning right at a solid red light after bringing the vehicle to a full stop
Answer
The correct order of right-of-way precedence from first to last is: (1) The emergency ambulance with active siren and flashing lights, (2) The sedan proceeding straight on a solid green light, (3) The pickup truck making an unprotected left turn on a solid green light, and (4) The compact car turning right on a solid red light after coming to a complete stop.
Standard traffic laws establish a clear hierarchy for intersection right-of-way. Emergency vehicles with active warning lights and sirens always receive top priority. Among non-emergency traffic, vehicles traveling straight on a green signal have priority over turning traffic. An unprotected left turn on green yields to oncoming straight traffic, but takes precedence over vehicles facing a red signal. Finally, turning right on red requires a complete stop and yielding to all traffic proceeding on a green light.
