Lighting and Reflector Violations (FMCSA Codes 393.9, 393.11)

Lighting and Reflector Violations (FMCSA Codes 393.9, 393.11): What Truckers Need to Know

Lighting and reflectors are essential for visibility and safety on the road. Violations under FMCSA Codes 393.9 and 393.11 are among the most common reasons commercial trucks are placed Out-of-Service (OOS) during inspections. For new authority carriers, these violations can lead to increased insurance costs, downtime, and a damaged safety record.

Understanding how to stay compliant with lighting and reflector requirements is critical to keeping your truck moving and your business protected.

What Are FMCSA Codes 393.9 and 393.11?

The Federal Motor Carrier Safety Administration sets strict standards for vehicle lighting and visibility:

• FMCSA Code 393.9 requires that all lamps, reflective devices, and associated equipment be in proper working condition at all times.
• FMCSA Code 393.11 outlines the specific lighting and reflector requirements for commercial motor vehicles, including placement, color, and visibility standards.

These regulations ensure your truck is visible to other drivers, especially in low-light or hazardous conditions.

Why Lighting and Reflector Violations Are Serious

Lighting violations may seem minor, but they can create dangerous situations on the road.

Key Risks Include:

• Reduced visibility at night or in bad weather
• Increased risk of rear-end collisions
• Difficulty signaling turns or stops
• Higher likelihood of roadside inspections and OOS orders

For new authority trucking companies, these violations also indicate poor maintenance practices to insurance providers.

Common Lighting and Reflector Violations

Knowing the most common issues helps you stay ahead of them.

1. Inoperative Headlights

Headlights must function properly for nighttime driving and low visibility conditions.

2. Faulty Brake Lights

Brake lights are critical for alerting drivers behind you when slowing or stopping.

3. Non-Working Turn Signals

Turn signals must be fully operational to communicate lane changes and turns.

4. Missing or Damaged Reflectors

Reflectors and reflective tape improve visibility, especially at night.

5. Improper Lighting Color or Placement

Lights must meet specific color and positioning requirements under FMCSA regulations.

6. Broken Clearance or Marker Lights

These lights indicate the size and width of your truck and are required for safety.

Out-of-Service Criteria for Lighting Violations

A truck may be placed out of service if:

• Required lights are not functioning
• Visibility is significantly reduced
• Brake lights or turn signals are inoperative
• Required reflectors are missing

Even a few non-working lights can lead to violations and, in some cases, OOS orders.
