What is considered a major violation for CDL holders?

Major violations include DUI, leaving the scene of an accident, using a CMV to commit a felony, driving a CMV with a revoked CDL, and causing a fatality through negligent CMV operation [§ 32-12A-1; 32-12A-40].

Can CDL holders attend traffic school?

In most jurisdictions, CDL holders cannot use traffic school to dismiss a moving violation [§ 49 C.F.R. 383.51]. Every conviction counts toward disqualification thresholds. This makes legal representation especially important for CDL holders.

What happens to my CDL if I get a traffic ticket in my personal vehicle?

CDL holders are held to higher standards even when driving personal vehicles [§ 32-12A-1; 32-12A-40]. A DUI in your personal vehicle results in CDL disqualification. Serious traffic violations in any vehicle count toward CDL disqualification thresholds.

How can I protect my CDL after a traffic violation?

Hire an attorney experienced in CDL defense immediately. They can often negotiate non-moving violation pleas that do not count toward CDL disqualification. Never simply pay a ticket — it is an admission of guilt.
