What if I have a CDL or would like to obtain one in the future?

First, you need to understand that it does not matter if you were driving a commercial vehicle or your private vehicle when you were stopped for driving while intoxicated or driving while under the influence. The legal limit for driving a noncommercial vehicle under the influence is .08% while if you were driving a commercial vehicle it is .04%. Suspension

The following major offenses will impact your ability to drive a commercial vehicle. Major offenses include: operating while intoxicated, operating under the influence of a controlled substance, refusal to test for intoxication, leaving the scene of an accident, operating a CMV while the CDL is disqualified, revoked, suspended, or canceled and causing a fatality through negligent or criminal operation of a CMV.

Suspension periods are different if you were driving a commercial vrs. noncommercial vehicle when you were stopped and the chart below reflects the suspension/revocation times for each.


Commercial Vehicle

1st offense

NOTE: The computation of time from offense to offense is the date of the ticket and not the date of conviction.

If your license is suspended or revoked, you cannot drive any commercial vehicle during the suspension or revocation period but you may apply for limited driving privileges to operate private, noncommercial, vehicles.
