What will happen if a self-canceling device on turn signals is inoperative?

If a self-canceling device on turn signals is inoperative, the vehicle should be failed during inspection. This is because the self-canceling feature is crucial for ensuring the safe operation of the vehicle. It automatically turns off the turn signals after the vehicle has completed a turn or lane change, which helps prevent confusion and potential accidents on the road.

When a driver forgets to turn off the signal manually, an inoperative self-canceling device can lead to the turn signal remaining on, misleading other drivers about the vehicle's intended actions. Therefore, for safety compliance and to promote responsible driving practices, a vehicle lacking this functional safety feature would not meet the inspection criteria, resulting in a failure.

The importance of this device goes beyond mere convenience; it is a fundamental safety feature that helps maintain clear communication between drivers on the road. Consequently, vehicles with such deficiencies are not deemed fit for safe operation.
