Commercial Driver (CDL) DUI Consequences in Washington: Unique Risks for Truck Drivers

For commercial drivers in Washington, a commercial driver’s license (CDL) is more than just a license, it is a livelihood. A single DUI charge can jeopardize years of training, investment, and career stability. While all DUI charges in Washington are serious, the consequences for CDL holders are especially severe because federal and state regulations impose stricter standards.

At the Law Office of Erin Bradley McAleer, we represent truck drivers and other commercial drivers facing DUI charges and help them understand what is at stake.

Lower Blood Alcohol Limit for CDL Holders

Most drivers in Washington are considered legally impaired with a blood alcohol concentration (BAC) of 0.08% or higher. However, CDL holders are subject to a stricter limit. Under RCW 46.25.110 and federal law, a commercial driver is considered impaired at just 0.04% BAC when operating a commercial vehicle. This means even a small amount of alcohol can lead to devastating consequences.

Administrative License Consequences

A DUI arrest for a CDL holder triggers an immediate administrative process through the Department of Licensing (DOL). Potential outcomes include:

  • One-year CDL disqualification for a first DUI conviction or refusal to take a breath or blood test.
  • Lifetime CDL disqualification for a second DUI conviction or refusal, even if years apart.
  • Separate suspension of personal driver’s license, which affects both personal and professional driving privileges.

Unlike some drivers, CDL holders are not eligible for an Occupational/Restricted License to continue driving commercially during suspension.

Criminal Penalties

In addition to CDL-specific consequences, CDL holders face the same criminal penalties as non-commercial drivers under RCW 46.61.502, including:

  • Jail time, fines, and probation.
  • Mandatory alcohol or drug treatment.
  • Ignition interlock requirements for personal vehicle use.

These penalties compound the damage to a commercial driver’s career.

Career and Employment Risks

Beyond the legal penalties, a CDL DUI can impact employment opportunities for years. Trucking companies are often prohibited by federal regulations or company policy from hiring drivers with DUI records. Insurance companies may refuse to cover drivers with DUI histories, making employment nearly impossible. Even a single DUI arrest, regardless of conviction, can result in immediate termination or disqualification from certain routes or contracts.

Defenses for CDL Holders

Every DUI case is different, and defenses may include:

  • Challenging the traffic stop or probable cause.
  • Questioning the accuracy of breath or blood testing.
  • Demonstrating procedural violations during the arrest.
  • Contesting whether the driver was actually operating a commercial vehicle at the time.

Because the consequences for CDL holders are uniquely harsh, it is critical to mount the strongest defense possible from the start.
