General Requirements


The requirements of this regulation do NOT apply to the following:

  • Covered vehicles with operable video equipment, or similar technological capability providing the driver with a full view behind the vehicle, are exempt from the requirement to use a ground guide.
  • To the extent that any federal Department of Transportation (DOT) regulation applying to covered vehicles conflicts with this chapter, the DOT regulation shall take precedence.
  • Covered vehicles that did not have a back up alarm when manufactured, or were not later retrofitted with an alarm, are exempt from the requirement to have a back up alarm. Note: If the manufacturer offered the employer a back up alarm retrofit package at a reasonable and economically feasible cost and the employer did not have the retrofit package installed, this exemption does not apply.

Go to OSHA's website for more information on covered construction vehicles and identified blind spots.


This regulation applies to all covered vehicles operating in reverse with an obstructed view to the rear.

No employer shall operate any covered vehicle in reverse unless:

  • The covered vehicle has a reverse signal (i.e. back up) alarm that is audible above the surrounding noise level, and
  • The covered vehicle is operated in reverse only when a designated observer or ground guide signals that it is safe to do so, or
  • Before operating the covered vehicle in reverse, the driver visually determines that no employee/pedestrian is in the path of the covered vehicle.

Note: If the back up alarm stops working properly and an immediate fix is not possible that day, the vehicle shall be backed up using ground guide signals or the vehicle be taken out of service until the alrm is repaired.
