CDL Disqualifications: What Can Cost You Your License

What Are CDL Disqualifications?

A CDL disqualification means you are legally prohibited from operating a commercial motor vehicle (CMV) for a specific period. Disqualifications are imposed by your state's licensing agency based on federal regulations set by the FMCSA. During a disqualification period, driving a CMV is a federal offense.

Disqualifications can be triggered by offenses committed in any vehicle (commercial or personal), though penalties are generally more severe for offenses in a CMV. There are three main categories: major offenses, serious traffic violations, and railroad crossing violations.

It is important to note that CDL disqualifications are separate from criminal penalties. You may face both a criminal sentence and a CDL disqualification for the same offense.

Major Offenses

Major offenses carry the most severe disqualification periods. A first offense results in a one-year disqualification (three years if you were transporting hazardous materials). A second major offense results in a lifetime disqualification.

Note: The BAC limit for CDL holders operating a CMV is 0.04%, which is half the standard 0.08% limit. You can be charged with DUI at a lower level while driving commercially.

Serious Traffic Violations

Serious violations accumulate over a three-year period. Two within three years triggers a 60-day disqualification; three triggers a 120-day disqualification.

• Excessive speeding (15+ mph over the posted limit)
• Reckless driving
• Improper or erratic lane changes
• Following too closely
• Driving a CMV without a CDL or proper endorsements
• Driving a CMV without the CDL in your possession
• Texting or using a handheld mobile phone while driving a CMV
• Any traffic violation (other than parking) connected to a fatal crash

Railroad Crossing Violations

Railroad crossing violations in a CMV carry specific disqualification periods:

• First violation: 60-day disqualification
• Second violation within 3 years: 120-day disqualification
• Third violation within 3 years: 1-year disqualification

Violations include failing to stop, failing to slow down, failing to have sufficient space to clear the crossing, and failing to obey traffic control devices at crossings.

Out-of-Service Order Violations

If you are placed out of service by an inspector and continue to drive, the penalties are severe:

• First violation: 180 days to 1 year disqualification
• Second violation within 10 years: 2 to 5 year disqualification
• Third violation within 10 years: 3 to 5 year disqualification

If you are transporting hazardous materials or 16+ passengers when you violate an OOS order, the disqualification periods increase significantly.

Lifetime Disqualifications

The following result in lifetime CDL disqualification with no possibility of reinstatement:

• Using a CMV in the commission of a felony involving manufacturing, distributing, or dispensing controlled substances
• A second conviction of any major offense listed above

Other lifetime disqualifications (from a single major offense) may be eligible for reinstatement after 10 years if your state allows it and you meet rehabilitation requirements.

Getting Reinstated

After a disqualification period ends, reinstatement is not always automatic. You will typically need to:

1. Wait the full disqualification period
2. Complete any court-ordered requirements (alcohol/drug programs, community service)
3. Pass a current DOT physical
4. Pay reinstatement fees to your state DMV
5. In some cases, retake the CDL knowledge and skills tests
6. Complete any required return-to-duty drug/alcohol testing if applicable

Even after reinstatement, your violation history follows you. Many carriers run background checks going back 3 to 10 years, and past disqualifications will affect your employability. Building a clean record from reinstatement forward is essential.
