Top 5 Reasons Your MC Number Could Get Revoked (and How to Fix It)

Operating as a motor carrier in the U.S. requires compliance with federal and state regulations. One of the most critical credentials you need is your Motor Carrier (MC) Number, issued by the Federal Motor Carrier Safety Administration (FMCSA). However, failing to meet compliance standards can lead to an MC number, disrupting your trucking business. In this guide, we’ll explore the top 5 reasons your MC number could get revoked and provide actionable solutions to fix and prevent these issues.

Top 5 Reasons Your MC Number Could Get Revoked

1. Failing to Maintain Active Insurance (BIP & Liability Coverage)

Why It Gets Revoked:

The FMCSA requires all motor carriers to maintain active liability insurance (usually $750,000 for general freight) and, in some cases, cargo insurance. If your insurance lapses or gets canceled, the FMCSA will suspend or revoke your MC number, shutting down your operations.

How to Fix It:

• Monitor insurance expiration dates and renew policies on time.
• Work with a trusted insurance provider specializing in trucking.
• Use FMCSA’s online system to update insurance filings immediately.

2. Not Paying FMCSA Fees (HVUT & UCR)

Why It Gets Revoked:

Motor carriers must pay annual fees, including:

• Heavy Vehicle Use Tax (HVUT) (Form 2290)
• Unified Carrier Registration (UCR) fees

Missing these payments leads to penalties, fines, and MC revocation.

How to Fix It:

• File HVUT before August 31 each year (for vehicles over 55,000 lbs).
• Renew UCR registration annually (deadlines vary by state).
• Set payment reminders or use a compliance service for automatic filings.

3. Failing the FMCSA Safety Audit (New Entrant or Compliance Review)

Why It Gets Revoked:

New carriers undergo a New Entrant Safety Audit within 12 months of getting their MC number. If you fail due to:

• Unsafe driving records
• Lack of proper drug & alcohol testing programs
• Incomplete record-keeping

Your authority can be revoked.

How to Fix It:

• Prepare for audits with proper driver qualification files (DQFs).
• Implement a compliant drug & alcohol testing program.
• Use ELD (Electronic Logging Devices) to track Hours of Service (HOS).

4. Not Updating FMCSA Records (Address, Contact Info, Operating Status)

Why It Gets Revoked:

The FMCSA requires carriers to update changes in:

• Business address
• Contact information
• Operating status (active, inactive, out of business)

Failure to report changes can result in your MC number being flagged for revocation.

How to Fix It:

• Update FMCSA records within 30 days of any change.
• File MCS-150 biennially (every 2 years) to keep authority active.
• Use the FMCSA Portal to make quick updates.

5. Serious Safety Violations (CSA Score Too High)

Why It Gets Revoked:

The FMCSA’s Compliance, Safety, Accountability (CSA) program tracks safety violations. If your CSA score is too high due to:

• Repeated traffic violations
• Accidents involving fatalities
• HOS violations

Your MC number could be suspended or revoked.

How to Fix It:

• Train drivers on FMCSA safety regulations.
• Monitor CSA scores and dispute incorrect violations.
• Hire safer drivers with clean records.
