Driver's License Test Prep
New York Practice Construction Signs

The manual requires the reflective orange slow-moving vehicle triangle to appear where on construction equipment?

  1. A.
    On the roof of the cab
  2. B.
    On the back of the vehicle Correct
  3. C.
    On both side mirrors
  4. D.
    On the front bumper
The Why

The answer is "On the back of the vehicle"

The manual specifies the back of the vehicle so drivers overtaking from behind get the warning at the point it matters. Choice D is the trap for drivers who picture the triangle like a hazmat placard visible from any angle, when the manual limits the placement to the rear of the machine.

Why the others miss

The traps in the wrong answers

A. On the roof of the cab

The manual specifies the back of the vehicle, not the roof; the triangle warns traffic approaching from behind. This answer pictures the amber strobe beacons often bolted to the roof of a construction cab and mistakes them for the required orange triangle.

C. On both side mirrors

Side mirrors face the next lane over, not the vehicles closing from behind that the warning is meant for. This answer confuses the back-facing triangle with the side-visible reflectors that run along the length of a trailer.

D. On the front bumper

A front-bumper placement would not warn the drivers approaching from behind, who need the notice. This answer assumes any warning symbol should face forward, the way license plates and headlights do.
