Yes. Several non-DUI offenses can disqualify a CDL, a commercial driver's license, in California, including leaving the scene of a crash, using a vehicle to commit a felony, refusing a chemical test, and causing a fatality. A first conviction usually costs one year, a second costs a lifetime ban, and serious traffic or railroad-crossing violations add shorter periods.
Which non-DUI offenses disqualify a CDL, and for how long?
California law lists several non-DUI offenses, mostly defined without regard to the vehicle, that disqualify a CDL for one year on a first conviction and life on a second.
These statutes use "CMV," short for commercial motor vehicle, for the rules that apply only while driving commercially.
| Offense | First conviction | Second conviction (any combination) |
|---|---|---|
| Leaving the scene of an accident | 1 year | Life |
| Using a motor vehicle to commit a felony | 1 year | Life |
| Driving a CMV while disqualified, or on a revoked, suspended, or canceled CDL, for CMV-related reasons | 1 year | Life |
| Causing a fatality (vehicular manslaughter under Penal Code 192(c), or while intoxicated under 191.5) | 1 year | Life |
| Refusing or failing to complete a required chemical test | 1 year | Life |
| Evading a peace officer in a CMV (Vehicle Code 2800.1, 2800.2, or 2800.3) | 1 year | Life |
Caption: Vehicle Code 15300 (first conviction) and 15302 (second conviction, any combination of the listed offenses) disqualification periods for non-DUI offenses.
"A driver shall not operate a commercial motor vehicle for a period of one year if the driver is convicted of a first violation of any of the following: ... (5) Leaving the scene of an accident involving a motor vehicle operated by the driver. (6) Using a motor vehicle to commit a felony, other than a felony described in Section 15304. ... (8) Causing a fatality involving conduct defined pursuant to Section 191.5 of the Penal Code or subdivision (c) of Section 192 of the Penal Code. (9) While operating a motor vehicle, refuses to submit to, or fails to complete, a chemical test or tests in violation of Section 23612. (10) A violation of Section 2800.1, 2800.2, or 2800.3 that involves a commercial motor vehicle." (Vehicle Code section 15300(a))
If any of these happened while hauling hazardous material, the first-conviction period is three years instead of one (Vehicle Code section 15300(b)). The second-conviction lifetime bar in Vehicle Code 15302 counts any combination of two convictions from this same list, not necessarily two of the same offense. Leaving the scene, using a vehicle to commit a felony, causing a fatality, and refusing a test apply whether you were driving a commercial vehicle or your own personal car at the time; only driving on a revoked CDL and evading police in a CMV require that the vehicle itself was commercial. A felony involving manufacturing, distributing, or dispensing a controlled substance, or possession with intent to do so, is excluded from the "felony" item above because it has its own, stricter rule under Vehicle Code 15304, discussed below.
Does using a commercial vehicle for human trafficking carry its own rule?
Yes, since January 1, 2025, using a commercial vehicle for human trafficking disqualifies a CDL for life on the first conviction, with no second-conviction requirement.
"A driver shall not operate a commercial motor vehicle for the rest of their life if convicted of using a commercial motor vehicle in the commission of a felony involving an act or practice of severe forms of human trafficking, as described in Section 7102 of Title 22 of the United States Code. A driver shall not operate a commercial motor vehicle for the rest of their life if convicted of Section 236.1 of the Penal Code while using a commercial motor vehicle." (Vehicle Code section 15303)
This differs from the general "using a vehicle to commit a felony" item in the table above, which needs two separate convictions before it becomes a lifetime bar. A similar one-conviction lifetime rule applies to using a vehicle to commit a felony involving manufacturing, distributing, or dispensing a controlled substance, or possession with intent to do so (Vehicle Code section 15304).
What "serious traffic violations" can also disqualify a CDL?
California disqualifies a CDL for 60 days on a second serious traffic violation conviction within three years, and 120 days on a third, in a commercial or personal vehicle.
| Serious traffic violation | Second conviction (within 3 years) | Third or later conviction (within 3 years) |
|---|---|---|
| Speeding 15 mph or more over the limit | 60 days | 120 days |
| Reckless driving | 60 days | 120 days |
| Improper or erratic lane changes | 60 days | 120 days |
| Following another vehicle too closely | 60 days | 120 days |
| A traffic violation connected with a fatal accident | 60 days | 120 days |
| Driving a CMV without a CDL, or without the correct class or endorsement | 60 days | 120 days |
| Texting or using a hand-held phone while driving a CMV | 60 days | 120 days |
Caption: Vehicle Code 15306 and 15308 (violations listed in 15210(p)) and 49 CFR 383.51(c), Table 2: disqualification periods for repeated serious traffic violations.
"A driver shall not operate a commercial motor vehicle for a period of 60 days if the person is convicted of a serious traffic violation involving a commercial or a noncommercial motor vehicle and the offense occurred within three years of a separate offense of a serious traffic violation that resulted in a conviction." (Vehicle Code section 15306)
Vehicle Code 15308 sets 120 days for a third conviction within three years, and the federal table in 49 CFR 383.51(c) sets the same periods. A single serious traffic violation, by itself, does not disqualify a CDL under these rules.
What about railroad-crossing violations?
A CMV driver who violates a railroad-highway grade crossing rule, such as failing to stop or check that the tracks are clear, is disqualified starting with the first conviction.
Vehicle Code 15312 sets these periods in California for the listed railroad-crossing laws in a CMV: at least 60 days for a first conviction, at least 120 days for a second within three years, and at least one year for a third or later within three years. The federal table in 49 CFR 383.51(d) sets the same minimums.
Can a lifetime disqualification ever be reinstated?
California's Vehicle Code states its lifetime CDL bars without any reinstatement path; a federal rule lets a state offer one after 10 years and an approved rehabilitation program.
"A State may reinstate any driver disqualified for life for offenses described in paragraphs (b)(1) through (8) of this section (Table 1 to § 383.51) after 10 years, if that person has voluntarily entered and successfully completed an appropriate rehabilitation program approved by the State." (49 CFR 383.51(a)(6))
Table 1's own paragraphs (9) and (10), the felony drug-manufacturing-or-distribution disqualifier and the human-trafficking disqualifier, are each marked "Life-not eligible for 10-year reinstatement." The federal rule says a state "may" reinstate, so the 10-year path is a state option rather than a right; Vehicle Code 15302 and 15303 state the bar as lasting for the rest of the driver's life.
Is a restricted CDL available during any of these disqualifications?
No. Federal rules bar a state from issuing any commercial license, even a provisional or temporary one, that lets a disqualified driver operate a commercial vehicle.
"A State must not knowingly issue a CLP, a CDL, or a commercial special license or permit (including a provisional or temporary license) permitting a person to drive a CMV during a period in which: (a) A person is disqualified from operating a CMV ..." (49 CFR 384.210)
A disqualification under Vehicle Code 15300 to 15304 bars driving a commercial vehicle; whether your regular driving privilege is also suspended or revoked depends on the conviction itself. After a DUI conviction, Vehicle Code 13352(h) allows only a noncommercial restricted license, and DMV's DUI page says a CDL holder must downgrade to a Class C noncommercial license to get one. A DMV suspension for refusing a chemical test allows no restricted license at all (Vehicle Code 13353.4(a)).
Does this overlap with the DUI disqualification rules?
Yes, a CDL can also be disqualified for a DUI, including a second DUI conviction that results in a lifetime ban under the same Vehicle Code 15302.
The firm's commercial driver CDL DUI page covers the DUI-specific rules in depth, including whether a CDL is still possible after two prior DUI convictions.
What should a commercial driver do right away after a non-DUI charge?
Check the exact charge against the listed offenses, keep every record of the incident, and talk to a lawyer before any court date or plea.
Not every traffic or criminal charge triggers a CDL disqualification, so get the exact citation or charge first, and preserve any dashcam footage, accident reports, or other records. Federal rules set deadlines to tell your employer: within 30 days after a conviction for a traffic violation other than parking, in any vehicle (49 CFR 383.31), and by the end of the next business day after notice of a suspension or disqualification (49 CFR 383.33). Ask a lawyer how the specific charge, and any proposed plea, would affect your CDL.
What defenses come up in a case that could cost your CDL?
A defense in this kind of case often focuses on whether the offense of conviction actually matches a listed disqualifying category, since the exact charge controls the outcome.
Questions a lawyer will examine include whether the incident is properly characterized as "leaving the scene," "using a vehicle to commit a felony," or another listed category at all, whether a proposed reduction to a different, non-listed offense is realistic on the facts, and whether a prior conviction being combined toward the lifetime rule under Vehicle Code 15302 is itself a qualifying offense. No outcome is guaranteed, and which questions matter depends on the specific charge and record.
How does this relate to other driving and CDL questions?
Two other questions come up often: reckless driving as a serious traffic violation, and driving a CMV without the right license.
Reckless driving, one of the serious traffic violations above, has its own elements under Vehicle Code 23103. See the firm's answers on reckless driving in a parking lot and on when speeding becomes reckless driving for how that charge is proved.
Operating a CMV without a valid CDL of the appropriate class in your immediate possession violates Vehicle Code 15250(a)(1). The firm's driving without a license page covers the general charge of driving without a valid license.
Frequently asked questions
Does a non-DUI disqualification apply even if I was driving my own personal car?
For most of these offenses, yes. Leaving the scene, using a vehicle to commit a felony, causing a fatality, and refusing a chemical test apply regardless of the vehicle; only driving on a revoked CDL and evading police in a CMV require that you were driving a commercial vehicle.
Does a single serious traffic violation disqualify my CDL?
No. Under Vehicle Code 15306 and 15308 and the matching federal table, the 60- and 120-day periods start with a second serious traffic violation conviction within three years, in a commercial or a personal vehicle; a single violation does not trigger them.
Is railroad-crossing disqualification different from the serious traffic violation rule?
Yes. A railroad-crossing violation in a commercial vehicle can disqualify a CDL starting with the first conviction, at least 60 days, rather than only on a second conviction.
Is a lifetime disqualification for human trafficking ever reinstated?
No. Federal rules mark the human-trafficking and felony drug-manufacturing-or-distribution lifetime disqualifications as not eligible for the 10-year reinstatement path that a state may offer for the other listed major offenses.
Can I get a CDL if I already have two prior DUI convictions on a regular license?
That question involves the DUI-specific disqualification rules rather than the non-DUI offenses this page covers; see the firm's commercial driver CDL DUI page for that answer.
Does a reduced charge avoid CDL disqualification?
It depends on whether the reduced charge still matches one of the listed disqualifying categories. A charge that no longer fits any listed offense would not trigger disqualification under these statutes, but that depends entirely on the specific facts and the exact offense of conviction.
