Read this to your crew
Today's talk is about vehicles backing up: dump trucks, loaders, pickups, forklifts. The driver of a big truck cannot see directly behind it, and the mirrors leave gaps on both sides. A person standing in one of those gaps cannot be seen.
For drivers. Walk around the vehicle before you get in and before you back. Back up only as far as you need, and only when you know the path is clear. Use a spotter when you cannot see. If you lose sight of your spotter, stop, and do not move again until you see them.
For spotters. Stand where the driver can see you in the mirror, out of the vehicle's path, and never between the vehicle and something it could pin you against. Agree on the signals before the vehicle moves: back up, slow, stop. One spotter gives the signals. Watch the path, not your phone. If anyone walks into the path, signal stop.
For everyone else. Stay out from behind backing vehicles. Make eye contact with the driver before you walk near equipment. Do not assume the driver knows you are there because you can hear the alarm; with hearing protection on and other equipment running, you may not hear it at all.
The rules back this up. On a construction jobsite closed to public traffic, a motor vehicle with an obstructed rear view is used only with a reverse signal alarm audible above the surrounding noise, or backed up only when an observer signals that it is safe (29 CFR 1926.601(b)(4)). Earthmoving and compacting equipment has the same choice: a working reverse alarm or an employee signaling (29 CFR 1926.602(a)(9)(ii)).
An alarm warns the people who hear it; a spotter can see the person who does not. Plan the site so less backing is needed: one-way routes, turnaround areas, and walkways kept apart from equipment paths.
Three questions for the crew
- Where are the blind spots on the trucks and equipment we use today?
Listen for: Directly behind, both rear corners, and close in front of large equipment. - What are our signals for back up, slow and stop?
Listen for: Agreed hand signals. Have someone demonstrate them. - What does a driver do when the spotter disappears from view?
Listen for: Stop right away and wait until the spotter is back in sight.
What are OSHA's rules for backing vehicles?
In construction, the motor vehicle rules cover vehicles that operate within an off-highway jobsite not open to public traffic, and not the equipment of 29 CFR 1926.602 (29 CFR 1926.601(a)). No employer uses motor vehicle equipment with an obstructed view to the rear unless the vehicle has a reverse signal alarm audible above the surrounding noise level, or the vehicle is backed up only when an observer signals that it is safe to do so (29 CFR 1926.601(b)(4)).
Bidirectional machines such as rollers, compactors, front-end loaders and bulldozers have a horn distinguishable from the surrounding noise, used as needed when the machine moves in either direction and kept working (29 CFR 1926.602(a)(9)(i)). Earthmoving or compacting equipment with an obstructed view to the rear is used in reverse only with a reverse signal alarm distinguishable from the surrounding noise, or with an employee signaling that it is safe (29 CFR 1926.602(a)(9)(ii)).
The paragraphs, word for word:
“(4) No employer shall use any motor vehicle equipment having an obstructed view to the rear unless: (i) The vehicle has a reverse signal alarm audible above the surrounding noise level or: (ii) The vehicle is backed up only when an observer signals that it is safe to do so.”
“(9) Audible alarms. (i) All bidirectional machines, such as rollers, compacters, front-end loaders, bulldozers, and similar equipment, shall be equipped with a horn, distinguishable from the surrounding noise level, which shall be operated as needed when the machine is moving in either direction. The horn shall be maintained in an operative condition.”
“(ii) No employer shall permit earthmoving or compacting equipment which has an obstructed view to the rear to be used in reverse gear unless the equipment has in operation a reverse signal alarm distinguishable from the surrounding noise level or an employee signals that it is safe to do so.”
How often did OSHA cite these rules in FY2025?
| Standard | Construction sites | Other industries | All FY2025 citations |
|---|---|---|---|
| 29 CFR 1926.601Motor vehicles, construction | 36 | 5 | 41 |
| 29 CFR 1926.602Material handling equipment, construction | 237 | 14 | 251 |
Citation items under 29 CFR issued Oct 1, 2024 to Sep 30, 2025, at federal and State Plan inspections, counted by HazComFast on U.S. Department of Labor enforcement data (extracted Oct 13, 2026). Construction means an inspection whose NAICS code starts with 23. The counts describe inspected establishments, not every employer.
Who does what when a vehicle backs up?
| Role | Before the vehicle moves | While it moves |
|---|---|---|
| Driver | Walk around, agree on the signals, locate the spotter | Back only while the spotter is in view; stop when they are not |
| Spotter | Check the path, stand in the driver's view and out of the path | Watch the path, give clear signals, signal stop if anyone enters |
| Everyone else | Stay out of the area behind vehicles | Make eye contact with the driver before approaching |
