Struck-By
Moving Vehicles Are One of the Deadliest Hazards on a Job Site
Separate people from traffic before someone is struck
Dump trucks, loaders, and pickups sharing space with workers on foot cause a steady stream of struck-by and backover fatalities every year. Blind spots, backing without a spotter, and missing traffic control put people directly in the path of moving equipment. OSHA Scan analyzes job-site photos to flag workers on foot near active traffic, missing spotters and barriers, and crews without high-visibility gear before a vehicle moves.

What this scenario looks like
A moving-vehicle hazard exists any time construction equipment, delivery trucks, or personal vehicles share space with workers on foot without separation or traffic control. It shows up as a dump truck backing near a crew with no spotter, a loader operating in a congested lay-down yard, or delivery traffic driving through a pedestrian path because no barriers or routes were established.
In practice these hazards form from routine movement. A driver backs up relying on mirrors alone, a flagger position goes unfilled during a break, or foot traffic crosses an equipment route to save time. Large equipment has deep blind spots directly behind and beside the operator, so a worker standing in the wrong place is simply invisible from the cab.
The danger is that everything looks ordinary until the moment of contact. There is no barrier, no separation, and often no warning beyond an engine sound the worker has tuned out. A backing vehicle covers the last few feet before anyone can react. That everyday, invisible overlap of people and traffic is exactly what photo-based work-zone scanning is built to catch.

Why this scenario matters
Immediate consequences
Being struck or run over by a vehicle causes fatal crushing injuries, amputations, and severe trauma. Backover incidents are especially deadly because the worker is caught with no time or space to move clear.
Legal & financial impact
Motor-vehicle and equipment violations under OSHA's construction standards carry penalties up to $16,550 each and far more for willful or repeat findings, while a struck-by-vehicle fatality can trigger criminal referral and multimillion-dollar litigation.
Operational impact
A vehicle incident shuts down site logistics, triggers an OSHA investigation, and stalls deliveries and earthwork at thousands of dollars a day while insurance premiums and your experience modification rate climb.
Industry-specific concerns
Highway and road builders, earthwork contractors, and busy urban sites mix heavy equipment, deliveries, and public traffic with crews on foot, creating constant vehicle-pedestrian conflict.
How OSHA Scan detects this hazard
OSHA Scan uses an AI vision model to identify traffic hazards operators cannot see. Upload a photo of the work area and it locates workers on foot inside equipment paths, checks for spotters, barriers, and traffic routes, flags crews without high-visibility apparel, and cites the OSHA standard it may relate to with a severity rating — in seconds, before vehicles move.

Real incident case study
A backover in a congested lay-down yard
The situation
A tri-axle dump truck was maneuvering to dump aggregate in a tight lay-down yard where a small crew was staging materials on foot. The site had no internal traffic plan and no dedicated spotter for backing vehicles.
What went wrong
The driver began backing using mirrors only. A worker crouched behind the truck to pick up a strap was in the vehicle's blind spot and was struck and run over before the driver realized anyone was there, sustaining fatal injuries.
How OSHA Scan would have prevented it
A photo of the yard run through OSHA Scan before operations would have flagged workers on foot in the backing path and the absence of a spotter, cited 29 CFR 1926.601, and prompted the crew to assign a spotter, mark pedestrian routes, and separate foot traffic from backing vehicles.
Lessons learned
Backing is the deadliest vehicle movement on a site. Every backing operation needs a spotter or a rear-view system, pedestrian and vehicle paths must be physically separated, and a quick photo scan confirms no one is on foot in an equipment route before it is used.
Prevention best practices
Layered controls, from most to least effective.
Engineering controls
Physically separate people from moving vehicles.
- Establish and barricade dedicated pedestrian walkways separate from vehicle routes
- Install concrete or water barriers between traffic and work-on-foot zones
- Require functioning backup alarms and rear-view cameras on all equipment
- Use signs, cones, and channelizing devices to define one-way traffic routes
- Provide adequate lighting for all vehicle operations and night work
Administrative controls
Manage movement so people and vehicles never occupy the same space.
- Develop and post an internal traffic control plan for the site
- Assign trained spotters for all backing and blind-spot maneuvers
- Use flaggers and positive communication between drivers and ground crew
- Limit vehicle speeds and enforce designated haul routes
- Hold a toolbox talk on vehicle-pedestrian hazards for each phase
Personal protective equipment
The last line of defense for workers on foot near traffic.
- High-visibility apparel (Class 2 or 3) for everyone on foot in traffic areas
- Type I/II hard hats rated for impact
- Steel-toe footwear appropriate for the site
- Inspect high-visibility gear for wear and replace faded or torn items

Frequently asked questions
What is the most common moving-vehicle incident on a job site?
Backovers are the most common and deadly. The majority of struck-by-vehicle fatalities involve a vehicle backing up, because operators have deep blind spots directly behind the machine and workers on foot are often invisible from the cab.
When is a spotter required for backing?
OSHA requires a backup alarm audible above the noise level or an observer (spotter) confirming it is safe to move whenever a vehicle's view to the rear is obstructed. On congested sites a dedicated spotter is best practice for every backing maneuver.
What is an internal traffic control plan?
It is a site-specific plan that separates pedestrian and vehicle areas, sets haul routes and speed limits, and defines where deliveries enter and turn. It keeps workers on foot out of equipment paths and reduces vehicle-pedestrian conflict.
Why is high-visibility clothing so important around vehicles?
High-visibility apparel makes workers on foot far easier for operators to see, especially in low light, dust, or against complex backgrounds. Class 2 or 3 garments are standard for anyone working near moving vehicles.
How do blind spots make vehicles dangerous?
Large equipment has extensive blind zones behind and beside the operator where a person cannot be seen from the cab. A worker standing or crouching in a blind spot can be struck during a normal maneuver before the operator ever knows they are there.
What are the OSHA penalties for vehicle-safety violations?
Serious violations of the motor-vehicle and material-handling standards can exceed $16,000 each, and willful or repeat violations can top $165,000. A struck-by-vehicle fatality can also lead to criminal referral and major litigation.
How can I reduce struck-by-vehicle risk quickly?
Separate foot traffic from vehicles with barriers, assign spotters for backing, require high-visibility gear, enforce speed limits and haul routes, and verify backup alarms work. A quick photo scan of the area confirms these controls are in place.
How accurate is OSHA Scan at detecting vehicle hazards?
OSHA Scan detects work-zone traffic hazards. It flags workers on foot in equipment paths, missing spotters, and absent high-visibility gear, and returns the specific location and OSHA citation.

What the AI can and can't detect
OSHA Scan reads a single photo. That makes it fast and easy for anyone on site — but it also means it has real limits. Here's an honest look at both.
What it can catch from a photo
- Missing or incorrect PPE that is visible in the frame
- Unprotected edges, open holes, and visible fall hazards
- Housekeeping, trip, and blocked walkway or exit hazards
- Visible electrical, struck-by, and equipment-guarding hazards
What a photo can't tell it
- Hazards hidden from view or anything outside the photo
- Exact heights, distances, weights, or measurements
- Training records, procedures, or how equipment is actually used
- Full legal compliance or an official OSHA pass/fail determination
OSHA Scan gives an AI-assisted preliminary review from a photo. It does not replace an on-site inspection by a qualified safety professional, and a compliance score is not an official OSHA determination.
