812 OSHA Focus Four Hazards
Skip to main content

Motor Vehicles - Trucks, Cars, and More

When working on or near any construction zone:

  • wear high-visibility reflective clothing;
  • do not put yourself at risk of being struck by a vehicle and do not get caught in a situation where there's no escape route;
  • do not direct traffic unless you are the flagger;
  • flaggers must be visible by both motorists and equipment operators;
  • check that necessary warning signs are posted;
  • never cross the path of a backing vehicle;
  • if equipment doesn't have a reverse signal alarm loud enough to be heard against the surrounding noise level, and the operator has an obstructed view to the rear, the employer will designate a worker to signal when it's safe to back up; and
  • follow "Exit" and "Entry" worksite traffic plan.

Flaggers and other workers on foot are at greater risk of exposure to being struck; therefore, they must be visible by both motorists and equipment operators.

Your employer is required to ensure the necessary warning signs are placed along the road.

Your employer is required to:

  • conduct a hazard assessment of the worksite using the job-site coordinator (supervisor or foreman) who should:
    • make a thorough assessment of potential worksite safety hazards,
    • plan for work being conducted in close proximity to a public road or highway and for the safe handling of intermittent roadway traffic stoppages, such as a truck entering a roadway, and
    • plan the entry and exit to and from the worksite to reduce exposure to traffic;
  • post-construction areas with legible traffic signs at points of hazard;
  • erect barricades that conform to the MUTCD;
  • place necessary warning signs along the road; and
  • all workers on site should have a safety and operations orientation.
