Maintenance and Inspection Failures (FMCSA Codes 396.3, 396.9)

Maintenance and Inspection Failures (FMCSA Codes 396.3, 396.9): What Truckers Need to Know

Proper maintenance and inspections are the backbone of safe trucking operations. Violations under FMCSA Codes 396.3 and 396.9 are among the most common reasons commercial trucks are placed Out-of-Service (OOS) during roadside inspections.

For new authority carriers, maintenance and inspection failures can lead to increased insurance premiums, costly fines, downtime, and long-term compliance issues. Understanding the rules and implementing strong maintenance practices is essential to protect your business.

What Are FMCSA Codes 396.3 and 396.9?

The Federal Motor Carrier Safety Administration sets strict rules for vehicle maintenance and inspections:

• FMCSA Code 396.3 requires that carriers systematically inspect, repair, and maintain all vehicles under their control.
• FMCSA Code 396.9 mandates drivers to perform pre-trip, en route, and post-trip inspections and report any deficiencies.

Together, these regulations ensure vehicles are safe and reliable, reducing the risk of accidents and equipment failure.

Why Maintenance and Inspection Failures Are Serious

Vehicle maintenance issues directly impact safety, compliance, and insurance risk.

Key Risks Include:

• Brake, tire, or suspension failure
• Reduced vehicle control
• Increased accident likelihood
• OOS orders and costly repairs
• Negative CSA (Compliance, Safety, Accountability) scores

For new authority carriers, even minor maintenance oversights can signal poor safety practices to insurers.

Common Maintenance and Inspection Violations

Knowing the most frequent violations can help prevent them:

1. Skipped or Incomplete Pre-Trip Inspections

Drivers must check all critical systems and document deficiencies.

2. Failure to Repair Known Defects

Defective brakes, tires, or suspension components must be repaired promptly.

3. Missing or Incomplete Maintenance Records

FMCSA requires detailed documentation of inspections and repairs.

4. Overdue Preventive Maintenance

Regularly scheduled maintenance, such as oil changes, brake adjustments, and tire rotations, cannot be ignored.

5. Inadequate Vehicle Condition Reports

Any issues reported by drivers must be addressed immediately to avoid OOS violations.

Out-of-Service Criteria for Maintenance Failures

A vehicle can be placed out of service if:

• Defective brakes, tires, or steering components are found
• Required inspections are missing or incomplete
• Safety-critical defects are not repaired
• Vehicle condition compromises safe operation

Even small issues, if unaddressed, can escalate into violations that stop operations.

How Maintenance and Inspection Failures Affect Truck Insurance

Insurance providers view poor maintenance as a major risk factor.

Insurance Consequences:

• Higher premiums due to increased accident risk
• Stricter underwriting and potential coverage limits
• Greater scrutiny for claims related to equipment failure
• Negative impact on fleet safety ratings

Keeping vehicles properly maintained helps insurers view your fleet as low risk, reducing costs.
