Where to Find CDL Info

Becoming licensed to drive a commercial motor vehicle is a lengthy process, and at some point you might have questions.

DMV.org has covered the basics of applying for a CDL, obtaining commercial driver education, renewing your CDL and replacing a lost CDL, as well as state and federal CDL rules, equipment, and safety.

How can I find out more information about authorized routes?

New Hampshire's Department of Safety (DOS) provides to publications online regarding authorized routes:

• 53 foot and less trailers

• Double trailers

Both are available online.

I've been convicted of a traffic violation. How should I handle this regarding my CDL?

You'll need to tell your employer within 30 days of the conviction, unless it was a parking ticket.

I'm familiar with the classes and endorsements of CDLs, but what are the restrictions?

The following restrictions can be placed on CDLs in New Hampshire:

• Code A: No restrictions

• Code B: Corrective lens

• Code C: Mechanical aid

• Code D: Prosthetic aid

• Code E: Automatic transmission

• Code F: Outside mirror

• Code G: Limited to daylight only

• Code K: CDL intrastate only

• Code L: No air brakes

• Code O: Except tractor trailers

New residents transferring their CDLs to New Hampshire may have a Code T, which means it is temporary for six months.

I refused an alcohol test when I was pulled over last night. I know I wasn't over the limit, but I didn't want to be out-of-service, either―I had a drink or two. What happens now?

You should have risked being out-of-service for 24 hours, because refusing an alcohol test causes your CDL to be revoked.

My CDL has been suspended, but my boss let me make a big delivery this morning―I was caught. What now?

Both you and your employer face being fined up to $5,000 each, plus jail time.
