What Disqualifies You From Getting a CDL in Washington State?

Getting or keeping a commercial driver’s license in Washington can be blocked by any of several things: being too young, having a suspended base license, a serious criminal or driving conviction, alcohol or drug use (including any detectable THC), stacked traffic tickets, a failed DOT physical, an unresolved entry in the federal Drug and Alcohol Clearinghouse, or fraud on the application. Some of what disqualifies you from getting a CDL in Washington state has nothing to do with commercial driving at all. Federal rules in 49 CFR 383.51 and Washington’s own RCW 46.25.090 both apply, and violations in your personal car count against your CDL just as much as violations in a rig.

Age, Base License, and Residency Requirements

You must be at least 18 to apply.¹ An 18-year-old CDL holder is restricted to driving within Washington. Federal law sets the minimum at 21 for interstate driving and for any load carrying hazardous materials, so most long-haul work is off-limits until then.

Your CDL rides on top of a valid Washington driver’s license. If the base license is suspended, revoked, canceled, or surrendered for any reason, the CDL goes with it.² That includes non-driving problems like unpaid child support or a failure to appear in court.

You also need proof of U.S. citizenship or lawful permanent residency. Accepted documents include a valid U.S. passport, a government-issued birth certificate, or a Permanent Resident Card.³ Without one of the approved documents, you have to surrender the CDL entirely.p>

Major Offenses That Trigger a One-Year or Lifetime Ban

A single conviction for any of the following offenses means at least a one-year disqualification. If you were hauling hazardous materials at the time, it’s three years. A second conviction for any combination of these offenses, even years apart and even in a different state, is a lifetime ban.⁴

Driving any motor vehicle under the influence of alcohol or drugs
Leaving the scene of an accident involving a vehicle you were driving
Using any motor vehicle to commit a felony
Refusing a blood or breath test under implied consent laws
Operating a commercial vehicle while your CDL is already revoked, suspended, or canceled
Causing a death through negligent operation of a commercial vehicle, including vehicular homicide

Two offenses skip straight to a lifetime ban with no possibility of reinstatement: using a vehicle in a felony involving controlled substance manufacturing or distribution,⁵ and using a vehicle in any human trafficking offense under RCW 9A.40.100.⁴

For other lifetime disqualifications, Washington may reinstate a CDL after 10 years if you voluntarily complete a state-approved rehabilitation program. A second disqualifying conviction after reinstatement makes the ban permanent.⁵

Alcohol and Drug Limits, On Duty and Off

The alcohol and drug rules for CDL holders are tighter than for regular drivers, and they follow you into your personal car.

In a commercial vehicle, the BAC limit is 0.04%, half the standard 0.08%. Any measurable amount of THC while operating a commercial vehicle is disqualifying.⁴ That zero-tolerance THC standard catches Washington drivers off guard. Using marijuana lawfully on your day off doesn’t protect your CDL if any THC shows up in a DOT test or a commercial vehicle stop.

A DUI in your personal car triggers the same one-year CDL disqualification as one in a commercial vehicle. For drivers under 21, the personal-vehicle BAC threshold drops to 0.02%, and any THC concentration above 0.00 nanograms per milliliter is disqualifying. For drivers 21 and over in a personal vehicle, the THC limit is 5.00 nanograms per milliliter of whole blood.⁴

Stacked Serious Traffic Violations

You don’t need a criminal conviction to lose your CDL. Two serious traffic violations within three years is a 60-day disqualification. Three or more in three years is 120 days.⁵ These stack whether you were driving a commercial vehicle or your own car.

Washington counts the following as serious traffic violations:⁶

Speeding 15 mph or more over the posted limit
Reckless driving
Using a personal electronic device while driving, including holding a phone or texting, under RCW 46.61.672
Any traffic violation connected to a fatal accident
Driving a commercial vehicle without a CDL, without the CDL in your possession, or without the proper class or endorsements

The Department of Licensing can also designate additional violations as serious by rule.⁶

You Can’t Plead a Ticket Down

If you’re used to negotiating a ticket into a non-moving violation or attending traffic school to keep a conviction off your record, forget it once you hold a CDL. Federal law bars states from masking, deferring judgment, or offering diversion that would keep a CDL holder’s traffic conviction off the record.⁷ This applies to any vehicle in any state.

Railroad Crossing Violations

Railroad crossing violations in a commercial vehicle carry their own schedule, separate from the serious-violation system:

First violation: at least 60 days
Second violation within three years: at least 120 days
Third violation within three years: at least one year

⁵

Triggering conduct covers failing to slow down and check that tracks are clear, failing to stop when they aren’t clear, failing to stop when a stop is always required (passengers or hazmat), entering a crossing without room to clear the tracks, ignoring a traffic control device or officer’s directions, and having insufficient undercarriage clearance to cross safely.⁸

Violating an Out-of-Service Order

When a roadside inspector places you or your vehicle out of service, driving anyway is its own disqualifier, measured over a 10-year window:

First violation: 180 days to one year
Second violation within 10 years: two to five years
Third violation within 10 years: three to five years

Carrying hazardous materials or operating a passenger vehicle designed for 16 or more people bumps the ranges up. A first violation becomes 180 days to two years, and second and subsequent violations carry three to five years.⁵

Medical Disqualifications

Every applicant and every renewal candidate has to pass a DOT physical from a medical examiner on the FMCSA National Registry. Passing produces a Medical Examiner’s Certificate.⁹ Failing the standards, or letting the certificate lapse, disqualifies you.

Vision must be at least 20/40 in each eye, with or without correction, with at least 70 degrees of horizontal field in each eye and the ability to recognize standard traffic signal colors. You must also pass a hearing test.¹⁰ Hearing aids and corrective lenses are allowed.

A history of epilepsy or any seizure disorder is disqualifying, though federal waivers exist for drivers who can show a safe driving history and medical stability. Insulin-treated diabetes requires a separate exemption showing stable blood sugar control. Uncontrolled high blood pressure and certain heart conditions can also block certification, though a medical examiner has discretion to issue a time-limited certificate for a well-managed condition.¹¹

Sleep apnea isn’t named in the FMCSA rules, but examiners can’t certify a driver whose condition could interfere with safe operation. In practice they screen for risk factors: obesity, a large neck circumference (17 inches or more for men, 16 or more for women), family history, and being over 40. If the examiner suspects apnea, they can require a sleep study before signing the certificate.¹² A diagnosis alone isn’t automatic disqualification, but you’ll need to show effective treatment, usually CPAP use.

The Drug and Alcohol Clearinghouse

Since 2020, every CDL-related drug or alcohol violation is reported to the FMCSA Drug and Alcohol Clearinghouse, a federal database employers have to check. An employer must run a pre-employment query before hiring you.¹³ Your current employer must run an annual query on you as well. If you have an unresolved violation on file, no employer can put you behind the wheel of a commercial vehicle on public roads.

Violations stay in the Clearinghouse for five years or until you complete the return-to-duty process, whichever takes longer.¹⁴ Return-to-duty requires evaluation by a substance abuse professional, completion of any recommended treatment, and a negative return-to-duty test. Follow-up testing continues for up to five years after that. So even if your state-issued CDL card is technically valid, an unresolved Clearinghouse entry makes you unemployable as a commercial driver.

Fraud on the Application or Testing

Providing false information on a CDL application, faking a medical certificate, or misrepresenting your qualifications carries a minimum 60-day disqualification. A conviction for fraud related to CDL testing or issuance goes further: the CDL is disqualified and you cannot reapply for at least one year.¹⁵ That covers having someone else take a skills test for you or bribing an examiner. Washington records any fraud-related withdrawal on your permanent driving record.
