CDL Age Requirements

CDL Age Requirement in Illinois

Short answer: 18 to drive within Illinois, 21 to drive interstate or carry passengers. Here's what that means if you're thinking about training.

18+: Intrastate

At 18 you can get an Illinois CLP and CDL to drive commercial vehicles within Illinois only.

21+: Interstate

To cross state lines or haul passengers, you must be at least 21. Most OTR and regional jobs fall here.

No Upper Limit

There's no maximum age. You need to pass a DOT physical and keep your medical certificate current.
