Question

Difficulty: MediumRight-of-Way Rules at Intersections

Four vehicles approach an intersection simultaneously under different legal conditions. Arrange the vehicles in the correct order of right-of-way precedence, from first to proceed to last to proceed.

  1. 1An emergency vehicle with active flashing lights and siren approaching from the cross street.
  2. 2A passenger car traveling straight on the primary thoroughfare with no stop or yield control.
  3. 3A delivery truck stopped at a stop sign on the intersecting side street preparing to turn right.
  4. 4A sedan exiting a private commercial driveway intending to turn left onto the roadway.

Answer

The correct order of precedence from first to proceed to last to proceed is: the emergency vehicle with active signals, followed by the passenger car traveling straight on the main thoroughfare, then the delivery truck at the side street stop sign, and finally the sedan exiting the private driveway.
The correct order follows established legal right-of-way hierarchy: active emergency vehicles always hold top priority; vehicles on an uncontrolled primary thoroughfare proceed next; vehicles on controlled public side streets proceed once main traffic is clear; and vehicles entering from private driveways must yield to all traffic on public roads, placing them last.

Step-by-Step Solution

1
Identify emergency vehicle priority
The emergency vehicle with active lights and sirens receives first priority.
State traffic laws mandate that all road users yield right-of-way immediately to emergency vehicles operating under active light and siren conditions.
2
Determine right-of-way on public roadways by traffic control type
The passenger car continuing straight on the uncontrolled main road proceeds second.
Traffic on a main thoroughfare without yield or stop signs maintains precedence over controlled side streets and private access points.
3
Compare public side-street traffic controls against private entrance controls
The delivery truck at the public stop sign proceeds third, and the sedan exiting the private driveway proceeds fourth.
Vehicles exiting private property must yield to all traffic operating on public roadways, placing private driveway entrants behind vehicles waiting at established public roadway controls once primary traffic has cleared.
