Traffic signals at a four-way intersection are completely inoperative due to a power outage. Four road users approach the intersection: an Emergency Ambulance operating with active sirens and flashing lights heading East; Vehicle A (Northbound), which arrived at the intersection and came to a complete stop before any other standard vehicles; Vehicle B (Westbound), which arrived at the intersection at the exact same time as Vehicle C; and Vehicle C (Southbound), positioned to the right of Vehicle B. In what order must these vehicles be permitted to proceed through the intersection?
- 1Emergency Ambulance (Eastbound with active siren and flashing lights)
- 2Vehicle A (Northbound, arrived and stopped first among standard vehicles)
- 3Vehicle C (Southbound, arrived simultaneously with Vehicle B and is to Vehicle B's right)
- 4Vehicle B (Westbound, arrived simultaneously with Vehicle C and is to Vehicle C's left)
Cevap
The correct order of movement through the intersection is: Emergency Ambulance first, followed by Vehicle A, then Vehicle C, and finally Vehicle B.
The Emergency Ambulance moves first because active emergency vehicles carrying visual and audible warning signals possess top right-of-way priority. Once the ambulance clears, the intersection functions as a four-way stop due to the dark signal. Vehicle A arrived first among standard vehicles, so it proceeds next. Finally, between Vehicles B and C (which arrived simultaneously), Vehicle C is positioned to the right of Vehicle B, meaning Vehicle B must yield to Vehicle C. Thus, Vehicle C goes third and Vehicle B goes fourth.

Anahtar Kavram
Right-of-way hierarchy combining emergency vehicle overrides, inoperative signal procedures, arrival sequence priority, and the yield-to-the-right rule.
