When the Vehicle Breaks Down
OSHA and DOT have specific guidelines for truck breakdowns on highways to ensure safety for drivers and other road users.
OSHA Guidelines
While OSHA primarily focuses on workplace safety, its general duty clause requires employers to provide a safe working environment, including training drivers on proper procedures during breakdowns. Drivers must use personal protective equipment (PPE), such as high-visibility vests, when outside the vehicle to reduce risks.
Supervisor responsibilities when a breakdown occurs include:
- determining the nature of the breakdown and best course of action
- locating, contacting, and dispatching a vendor to facilitate repairs
- obtaining all vehicle repair records
DOT Requirements
The Department of Transportation (DOT) has specific regulations for truck breakdowns on highways to ensure safety. According to 49 CFR ยง 392.22, when a commercial motor vehicle stops on the traveled portion or shoulder of a highway for reasons other than necessary traffic stops, the driver must:
- Activate Hazard Lights: Hazard warning signal flashers must be turned on immediately and remain active until warning devices are placed.
- Deploy Warning Devices: Within 10 minutes, the driver must place reflective triangles, flares, or other approved warning devices:
- For two-lane roads: Place devices 10 feet behind, 100 feet behind, and 100 feet ahead of the vehicle.
- For divided or one-way roads: Place devices 10 feet behind, 100 feet behind, and 200 feet behind the vehicle.
- Near hills, curves, or obstructions: Adjust placement between 100 and 500 feet in the direction of the hazard.
