What alcohol level applies to a commercial driver?

Commercial drivers are held to a threshold of 0.04 percent while operating a commercial motor vehicle, which is half the 0.08 percent threshold that applies to ordinary drivers. Federal rules also require a driver to be placed out of service for a period after any detectable alcohol concentration during a commercial operation.

Can something that happened in my own car affect my CDL?

Yes. West Virginia law provides that a CDL holder can be disqualified from commercial driving based on violations committed while operating a noncommercial vehicle, where the violation results in the suspension, revocation, or cancellation of the person's driving privileges.

Why can't a CDL holder take a driving course to keep a ticket off the record?

Federal regulation prohibits states from masking a CDL holder's conviction, deferring imposition of judgment, or allowing a diversion program that would keep the conviction from appearing on the national commercial driving record. The prohibition covers traffic control law violations in any type of motor vehicle, with narrow exceptions for parking, vehicle weight, and vehicle defect violations.

Does one speeding ticket disqualify a commercial driver?

Generally not on its own. Speeding at an excessive level is in the category West Virginia law calls serious traffic violations, and disqualification for that category is triggered by repeat convictions within a three year period rather than by a single one. Major offenses, such as impaired driving or refusing a chemical test, are treated differently and can disqualify a driver on a first occurrence.

Does a violation in another state follow me home?

Yes. Commercial driving records are shared among the states through a national information system, and the federal rules against masking apply regardless of which state the violation occurred in. A conviction from another state generally appears on the commercial record maintained in the driver's home state.
