New York Practice Traffic Lights

You have stopped at an intersection because the traffic light is out of service. Under the manual, what is the only thing that lets you proceed without going through the right-of-way rules?

  1. A.
    Ten seconds pass with no cross traffic
  2. B.
    Your side of the intersection is empty
  3. C.
    A traffic officer tells you to continue Correct
  4. D.
    The vehicle in front of you begins to move
The Why

The answer is "A traffic officer tells you to continue"

When a traffic light is out of service, the manual sends you into the right-of-way rules unless a traffic officer waves you through. Choice D is the trap: drivers used to following the car ahead assume that once traffic starts flowing they can flow with it, but the manual gives no such carve-out and names the officer as the one exception.

Why the others miss

The traps in the wrong answers

A. Ten seconds pass with no cross traffic

A self-timed wait is not the exception the manual names, so you still must apply the right-of-way rules unless a traffic officer directs you. This answer trusts a self-imposed count as a substitute for the right-of-way procedure, a habit the manual never authorizes at an out-of-service light.

B. Your side of the intersection is empty

An empty intersection does not remove the requirement to apply the right-of-way rules. This answer reads a clear stretch of pavement as if it functioned as a green light, a shortcut the manual never sanctions in place of the right-of-way analysis.

D. The vehicle in front of you begins to move

The manual does not treat the vehicle ahead of you as an exception to the right-of-way rules at a dark light. This answer extends the everyday habit of following the car ahead through a queue, treating movement in the lane as if it replaced the right-of-way analysis the manual actually requires.
