Four vehicles arrive at an intersection controlled by four-way stop signs under different conditions. Place the vehicles in the correct order in which they have the right-of-way to proceed through the intersection legally.
- 1An ambulance approaching with active sirens and emergency lights activated.
- 2A sedan that arrived and came to a complete stop before any other standard vehicle.
- 3A pickup truck traveling straight that arrived simultaneously with an oncoming left-turning vehicle.
- 4A coupe attempting a left turn across traffic that arrived simultaneously with the oncoming pickup truck.
Answer
The correct order of proceeding through the intersection is: 1) Emergency ambulance with active siren/lights, 2) Sedan that stopped first among non-emergency vehicles, 3) Pickup truck proceeding straight after simultaneous arrival, 4) Coupe turning left after yielding to oncoming straight traffic.
Right-of-way rules establish a clear hierarchy: active emergency vehicles hold absolute priority first. Next, multi-way stop rules grant precedence to whichever non-emergency vehicle stopped first (the sedan). Finally, when remaining vehicles arrive simultaneously, straight-through traffic (the pickup truck) has precedence over left-turning traffic (the coupe), placing the turning vehicle last.
