A CDL holder in Washington drives under the same traffic laws as everyone else, but a conviction reaches much further. This article explains how Washington traffic tickets are handled differently for commercial drivers: what counts as a serious violation, how disqualification periods work, why a DUI in a personal vehicle still costs the commercial privilege, and why the usual ways of resolving a ticket are not available.
The federal standard Washington enforces
Commercial licensing runs on a national floor. The Federal Motor Carrier Safety Administration sets the disqualification rules in 49 CFR 383.51, and Washington adopts them through the Uniform Commercial Driver’s License Act at RCW 46.25.090. Federal law separately directs every state to disqualify commercial drivers for defined offenses under 49 U.S.C. § 31310.
Two consequences run in parallel. A commercial driver convicted of a moving violation pays the ordinary fine and takes the ordinary consequences on the driving record, and separately faces disqualification of the privilege to operate any commercial vehicle. Disqualification is not a criminal penalty. It is a licensing action that follows automatically from the conviction.
What counts as a serious traffic violation
Washington defines a “serious traffic violation” at RCW 46.25.010, tracking the federal list in 49 CFR 383.51. As of 2026 the category includes:
- Excessive speeding, meaning 15 mph or more over the posted limit
- Reckless driving under state or local law
- Improper or erratic lane changes
- Following the vehicle ahead too closely
- Any traffic violation connected with a fatal accident
- Driving a commercial vehicle without the proper class of CDL or the required endorsements
- Driving a commercial vehicle without holding a CDL
- Driving a commercial vehicle without the CDL in the driver’s possession
- Texting or using a handheld phone while driving a commercial vehicle
An ordinary driver might see one of these as a routine ticket. For a commercial driver it is a violation the licensing system counts.
How disqualification periods add up
A single serious violation does not disqualify a CDL. The consequences begin with the second. Under RCW 46.25.090 and 49 CFR 383.51, a second serious violation in a commercial vehicle within three years results in a 60-day disqualification, and a third within three years results in 120 days. The window counts convictions arising from separate incidents, so the violations do not have to be related to stack.
Major offenses, including a DUI in a personal vehicle
Some offenses are disqualifying on the first conviction. RCW 46.25.090 and 49 U.S.C. § 31310 impose a one-year disqualification for a major offense, extended to three years when the driver was hauling hazardous materials. Major offenses include driving under the influence, refusing a breath or blood test, leaving the scene of an accident, using a vehicle to commit a felony, and driving a commercial vehicle while already disqualified. A second major offense results in a lifetime disqualification, which may later be reduced to a period of not less than 10 years.
The alcohol threshold is stricter for commercial drivers. A CDL holder is treated as driving under the influence at a blood alcohol concentration of 0.04 while operating a commercial vehicle, half the 0.08 level that applies to other drivers, under 49 CFR 383.51.
The consequence follows the license, not the vehicle. A DUI in the driver’s own car, off duty, still disqualifies the CDL under RCW 46.25.090. The criminal case proceeds like any other first-offense matter, covered in Washington’s DUI laws and first-offense penalties, but the hit to the commercial privilege is separate and automatic.
Why a deferred finding is off the table
Other Washington drivers can often ask the court for a deferred finding, which holds a traffic infraction off the record if the driver stays violation-free for a set period. That option is closed to commercial drivers. Federal law at 49 CFR 384.226 prohibits any state from masking, deferring, or diverting a commercial driver’s conviction so that it stays off the driving record, and Washington complies. The prohibition applies even to a violation committed in a personal vehicle.
For a CDL holder that changes how a ticket plays out. The deferred finding that resolves an ordinary speeding ticket cannot keep the same violation off a commercial record. Contesting the ticket at a hearing, where the goal is a dismissal or a finding that the violation was not committed, is the remaining way to avoid a conviction.
Reporting a conviction
A commercial driver has to report a conviction, not just absorb the licensing consequence. Under 49 CFR 383.31, a driver convicted of a traffic violation in any vehicle (other than parking) must notify the employer in writing within 30 days, and must notify the licensing state when the conviction happened in another state. These duties apply whether or not the violation leads to disqualification.
Frequently asked questions
Does a speeding ticket in my personal car affect my CDL?
It can. A conviction for excessive speeding, meaning 15 mph or more over the limit, is a serious traffic violation under RCW 46.25.010 whether it happens in a commercial or a personal vehicle, and serious violations count toward the disqualification thresholds in RCW 46.25.090. A single serious violation does not disqualify a CDL by itself; the second and third within three years do.
What is the alcohol limit for a CDL holder?
A commercial driver is treated as under the influence at a blood alcohol concentration of 0.04 while operating a commercial vehicle, half the 0.08 threshold for other drivers, under 49 CFR 383.51. This lower limit reflects the higher standard federal law sets for commercial operation.
Can a deferred finding keep the ticket off my record?
No. Federal law at 49 CFR 384.226 prohibits a state from masking or deferring a commercial driver’s conviction, so Washington courts cannot grant a CDL holder the deferred finding available to other drivers. The prohibition applies even when the ticket was issued in a personal vehicle.
How long does a disqualification last for a first DUI?
A first major offense, including DUI, results in a one-year disqualification of the commercial privilege under RCW 46.25.090, or three years if the driver was transporting hazardous materials at the time. A second major offense results in a lifetime disqualification, which may be reduced to not less than 10 years.
Do I have to tell my employer about a ticket?
A commercial driver convicted of any traffic violation other than parking must notify the employer in writing within 30 days under 49 CFR 383.31, whether the violation occurred in a commercial or a personal vehicle. A conviction in another state also has to be reported to the driver’s home licensing state.
