New York Practice Traffic Lights

A white stop line is painted across your lane at a red traffic light. Where must you bring your vehicle to a stop?

  1. A.
    Just past the line to see cross traffic
  2. B.
    On top of the line so the sensor detects you
  3. C.
    Before you reach the stop line Correct
  4. D.
    Anywhere in the crosswalk past the line
The Why

The answer is "Before you reach the stop line"

When a stop line is painted at an intersection, you must stop before you reach it, not on it and not past it. Choice A is the trap: drivers who habitually creep past a stop sign to see around parked cars carry that same habit through a red light, though the stop-line rule fixes the stopping point behind the paint.

Why the others miss

The traps in the wrong answers

A. Just past the line to see cross traffic

Rolling past the line to spot cross traffic breaks the stop-line rule at a red light. This answer carries over the habit of creeping past a stop sign to see around parked cars and applies that same instinct at the light.

B. On top of the line so the sensor detects you

Signal detection does not change the required stopping point; you still stop before the line. This answer treats the painted line as the spot the wheels must sit on to trigger a sensor, rather than a limit line the car stops before.

D. Anywhere in the crosswalk past the line

Halting inside the crosswalk overshoots the required point and blocks pedestrians on foot. This answer reads the two paint marks as one and picks the wider crosswalk stripes as the stopping mark, treating the thinner stop line as advisory.
