Difficulty: MediumTurning Procedures and Signaling

A driver operating a vehicle with non-functioning electronic turn signals needs to inform surrounding traffic that they intend to slow down and come to a stop. Which hand-and-arm signal must the driver display out of the driver-side window?

  1. Arm extended downward with the palm facing to the rearAnswer
  2. B
    Arm extended straight out horizontally from the vehicle
  3. C
    Arm extended upward at a 90-degree angle
  4. D
    Arm extended out and moving in a continuous sweeping circular motion

Answer

The driver must extend their left arm downward out of the window with the elbow bent and palm facing to the rear.
The correct signal for slowing down or stopping requires extending the left arm out of the window and pointing the forearm and hand straight down toward the ground with the palm facing backward. This position allows trailing drivers to recognize braking intent even when tail lights or brake lights are inoperative.

Step-by-Step Solution

1
Identify the driver's intended maneuver
The driver intends to decrease speed and bring the vehicle to a stop.
Different driving actions (left turn, right turn, stop) correspond to specific standardized manual arm positions.
2
Determine the legal hand-and-arm signal rule for stopping
Standard traffic regulations mandate extending the left arm out the window and bending it downward at a right angle with the palm pointing backward.
This distinct posture ensures clear visibility to following motorists that the vehicle is braking or stopping.
