CDL Suspension: What It Means for Drivers and Employers

Jul 15, 2025

6 min

For those in the transportation and logistics industry, a Commercial Driver’s License (CDL) is the key to maintaining a career behind the wheel. However, a CDL suspension can disrupt a driver’s livelihood and an employer’s operations.

Whether you’re a driver trying to avoid suspension or an employer managing a fleet, it’s crucial to understand what CDL suspension entails, how it happens, and what steps to take if it affects you.

What is CDL Suspension?

A Commercial Driver’s License (CDL) suspension is when a driver's ability to operate a commercial vehicle is temporarily or permanently revoked due to a violation of laws or regulations set forth by the Department of Transportation (DOT) or the Federal Motor Carrier Safety Administration (FMCSA).

A CDL suspension can have severe consequences for both the driver and their employer, impacting everything from job stability to operational efficiency.

Common Reasons for CDL Suspension

There are several reasons why a CDL might be suspended. Some of the most common causes include:

1. Driving Under the Influence (DUI)

One of the most serious offenses that can lead to a CDL suspension is driving under the influence of alcohol or drugs. For commercial drivers, the legal blood alcohol concentration (BAC) limit is much stricter than for personal vehicle drivers. A BAC of 0.04% or higher can result in an immediate suspension, and in some cases, the suspension may be permanent.

2. Violating Hours of Service (HOS) Regulations

The FMCSA enforces strict regulations on the number of hours a commercial driver can work to prevent fatigue-related accidents. If a driver is caught violating these regulations repeatedly or dangerously, their CDL may be suspended.

3. Accumulating Serious Traffic Violations

Just like non-commercial drivers, CDL holders are expected to obey the laws of the road. However, commercial drivers are held to higher standards. Serious violations like reckless driving, excessive speeding, or illegal lane changes can result in points on the driver’s record, and repeated offenses may lead to suspension.

4. Drug and Alcohol Violations

CDL holders must submit to random drug and alcohol tests, and failing these tests can lead to suspension. Even a single positive test for drugs or alcohol can be grounds for suspension, and multiple violations may lead to permanent revocation of the CDL.

5. Safety Violations and Accidents

If a commercial driver is involved in a serious accident or repeatedly violates safety regulations, their CDL can be suspended. This can include violations such as improper loading of cargo or driving with expired permits.

Consequences of a CDL Suspension

A suspended CDL can have severe impacts on a driver’s career. For drivers, losing the ability to operate a commercial vehicle means no income and potentially a long wait before they can get back to work.

The specific penalties depend on the type of violation and whether it’s a first-time offense or a repeat violation.

Employers also feel the impact. A suspended CDL can leave an employer with gaps in their workforce, leading to delays, reduced productivity, and increased operational costs. It may also affect the company’s insurance premiums or create legal complications if a driver is caught operating a vehicle with a suspended license.

How to Avoid CDL Suspension

Both drivers and employers can take proactive steps to avoid CDL suspension.

For Drivers:

  • Follow the Law: Always abide by traffic laws and regulations, especially regarding alcohol consumption, speed limits, and safety rules.

  • Stay Healthy and Rested: Fatigue is one of the biggest risks in the industry. Always follow HOS regulations and avoid working beyond your limits.

  • Pass Drug and Alcohol Tests: Regularly submit to and pass random drug and alcohol tests to avoid suspensions due to violations.

  • Drive Responsibly: Avoid reckless driving or dangerous behaviors that can result in accidents or violations.

For Employers:

  • Monitor Driver Records: Regularly check your drivers’ CDL statuses to ensure they are in good standing. This includes reviewing violations, accidents, and other incidents.

  • Ensure Compliance: Ensure that your drivers follow all FMCSA regulations, including HOS rules and drug and alcohol testing.

  • Provide Training: Offer training to your drivers on safe driving practices and regulations to help them avoid violations and suspensions.

The Difference Between CDL Disqualification and Suspension

When it comes to the legal status of a CDL license (Commercial Driver’s License), two terms that often come up are CDL disqualification and CDL suspension.

While they might seem similar, they refer to different legal actions with distinct consequences for CDL drivers and their ability to operate commercial motor vehicles (CMVs). Understanding the differences between these two terms is essential for both drivers and employers in the transportation industry.

CDL Suspension

A CDL suspension occurs when a CDL driver loses the right to operate a commercial motor vehicle temporarily due to certain violations or infractions. When a driver’s CDL license is suspended, they are prohibited from operating any motor vehicles for a specific period. Suspension typically happens due to reasons such as:

  • Driving under the influence (DUI) of drugs or alcohol

  • Excessive speeding or other serious traffic violations

  • Failure to meet medical requirements or physical fitness standards for driving

  • Accumulating too many points for traffic violations

The suspension is a temporary measure, and the driver can typically have their CDL reinstated after fulfilling specific requirements, such as paying fines, completing rehabilitation programs, or waiting out the suspension period.

CDL Disqualification

On the other hand, CDL disqualification is more severe and usually arises from more serious violations or multiple offenses. A disqualified driver loses the privilege to drive a commercial motor vehicle for an extended period or permanently. Disqualification often occurs when a CDL driver commits severe offenses, such as:

  • Driving a CMV with a suspended or revoked CDL

  • Serious accidents or reckless driving resulting in fatalities or significant injuries

  • Multiple DUI offenses

  • Drug and alcohol test refusals

Unlike suspension, CDL disqualification means the driver is no longer eligible to operate commercial motor vehicles under any circumstances.

The disqualification can be temporary or permanent, depending on the nature of the violation, and the CDL driver may need to meet stringent requirements, including additional testing or completing mandated programs, before they can even attempt to have their CDL reinstated.

Key Differences

  • Duration: A CDL suspension is typically temporary, while a disqualified driver faces longer-term or even permanent ineligibility to operate a commercial motor vehicle.

  • Severity of Offenses: A suspension is usually related to violations like speeding or medical issues, while disqualification is for serious offenses like multiple DUIs, drug test refusals, or serious accidents.

  • Reinstatement: While both suspensions and disqualifications can eventually lead to CDL reinstated, disqualification often has stricter criteria and may involve more substantial penalties.

Regaining a Suspended CDL

For drivers who face a CDL suspension, regaining their license often requires meeting specific criteria, such as:

  • Paying Fines or Fees: Drivers may need to pay fines or court fees as part of their reinstatement process.

  • Completing Rehabilitation Programs: In cases of substance abuse violations, drivers may be required to attend drug and alcohol rehabilitation programs.

  • Passing Tests: Some drivers may need to pass written exams, road tests, or drug screenings before their CDL can be reinstated.

  • Waiting Out the Suspension Period: Some suspensions require a waiting period before the CDL can be reinstated, depending on the severity of the offense.

A CDL suspension is a serious matter that affects not only the driver’s career but also the employer’s operations. Whether it’s due to a DUI, violation of HOS regulations, or another serious traffic violation, understanding the reasons behind a suspension, its consequences, and how to avoid it is crucial.

For both drivers and employers, staying compliant with safety regulations and taking preventative measures is the best way to keep everyone on the road and avoid costly disruptions.
