Fleet Vehicle Visibility in Work Zones Safety

Key Hazards

• Fleet vehicles not seen by passing traffic
• Blocked sightlines around curves, hills, or parked equipment
• Poor visibility during darkness, rain, fog, or snow
• Dirty or damaged lights and reflective markings
• Workers exposed outside the protected vehicle area
• Traffic entering or drifting into the work zone

2–3 Minute Talk Script

Fleet vehicle visibility is one of the first layers of protection in a work zone. If drivers do not see the vehicle early enough, they may not slow down, move over, or recognize that workers are nearby.

Warning lights, strobes, flashers, reflective markings, cones, signs, and vehicle position all work together. No single item should be relied on by itself, especially when traffic is fast, distracted, or visibility is poor.

Vehicle positioning matters. Trucks should be placed where they can be seen by approaching traffic and, when appropriate, provide protection for workers. Curves, hills, intersections, driveways, parked cars, and equipment can all block sightlines.

Visibility must be reassessed as the job changes. A vehicle that was visible at setup may become hidden by equipment, material piles, changing traffic patterns, darkness, rain, fog, snow, or sun glare.

Lights and reflective surfaces should be kept clean and functional. Mud, salt, dust, snow, and road grime can reduce visibility quickly, especially during winter operations or wet roadway work.

Workers should avoid standing in blind spots or exposed areas around fleet vehicles. Drivers may focus on the flashing lights and fail to notice workers stepping into traffic or moving behind equipment.

Good communication is important when vehicles enter, leave, or reposition within the work zone. Backing, turning, and pulling into traffic should be planned so workers and nearby drivers are not surprised.

A visible fleet vehicle gives approaching drivers time to react. The goal is to make the work zone obvious early, protect the crew, and avoid creating new hazards through poor placement or blocked visibility.

Safety Reminders

• Use warning lights and flashers appropriately.
• Keep reflective markings and lights clean.
• Position vehicles where approaching traffic can see them.
• Recheck visibility as weather, lighting, and work conditions change.
• Avoid standing in blind spots or exposed traffic areas.
• Communicate before moving or repositioning vehicles.
• Do not assume drivers see the work zone.

Ask the Crew

• Can approaching drivers see the fleet vehicle early enough?
• Are warning lights, flashers, and reflective markings working?
• Are curves, hills, equipment, or parked vehicles blocking sightlines?
• Has visibility changed because of weather, darkness, or traffic?
• Are workers staying out of exposed areas around the vehicle?
