Overweight / Overloading Violations (FMCSA Code 658.13): What Truckers Need to Know

Overweight and overloading violations are a major concern in the trucking industry. Under FMCSA Code 658.13, commercial motor vehicles must comply with federal weight limits to ensure safe operation on public roads.

For new authority carriers, violating weight regulations can lead to fines, Out-of-Service (OOS) orders, cargo issues, and increased commercial truck insurance premiums. Understanding how to stay compliant is essential to protecting your business.

What Is FMCSA Code 658.13?

The Federal Motor Carrier Safety Administration regulation 658.13 governs size and weight limits for commercial motor vehicles operating on the National Network of highways.

Key Federal Weight Limits:

• 80,000 lbs gross vehicle weight (GVWR)
• 20,000 lbs per single axle
• 34,000 lbs per tandem axle

These limits are in place to protect road infrastructure and ensure vehicle safety.

Why Overweight Violations Are Serious

Operating an overweight truck creates multiple safety and compliance risks.

Key Risks Include:

• Increased stopping distance
• Higher likelihood of brake failure
• Tire blowouts due to excess stress
• Structural damage to roads and bridges
• Reduced vehicle control

Because of these risks, overweight violations are strictly enforced and can lead to immediate penalties.

Common Overweight / Overloading Violations

Understanding how these violations occur can help you avoid them.

1. Exceeding Gross Vehicle Weight

Operating above the 80,000-pound federal limit without proper permits.

2. Axle Weight Violations

Even if total weight is legal, exceeding axle limits can result in citations.

3. Improper Load Distribution

Uneven weight distribution can overload specific axles.

4. Failure to Scale Loads

Skipping weigh stations or failing to verify weight before transport.

5. Lack of Oversize/Overweight Permits

Operating overweight without required state permits.
