Several road users arrive at a signalized intersection at the same time. Place the following road users in the correct order of right-of-way precedence, starting with the road user who has the highest priority to proceed first (Position 1) and ending with the one who must yield to all others (Position 4).
- 1An ambulance responding to an emergency with active siren and flashing lights
- 2A pedestrian crossing within a marked crosswalk with a illuminated 'WALK' signal
- 3A sedan proceeding straight through the intersection on a circular solid green light
- 4A SUV turning left across oncoming traffic on a circular solid green light
Answer
The correct order of right-of-way precedence from first to proceed to last is: 1) The emergency ambulance with active siren and lights, 2) The pedestrian crossing in a marked crosswalk on a walk signal, 3) The sedan proceeding straight on a solid green light, and 4) The SUV making an unprotected left turn on a solid green light.
Emergency vehicles operating with active siren and flashing lights hold primary priority over all traffic controls and other road users. Next, pedestrians crossing in a marked crosswalk with a walk signal hold right-of-way over non-emergency motorized vehicles. Among non-emergency vehicles facing a circular green light, straight-through traffic has right-of-way precedence over oncoming vehicles executing an unprotected left turn. Therefore, the left-turning vehicle must yield to all other users before proceeding.
