Are back-up alarms, hazard lights, or blinkers required to be on a forklift?
The operator horn is the only required warning device to be on every forklift in the U.S. It must be easily accessible and it must work. Back-up alarms, hazard lights, and blinkers are not required unless operating conditions require them to be present. However, if a back-up alarm or lighting system is attached to the truck, then it must work. OSHA will issue a fine for having an inoperable warning device on the forklift.
