How long does CDL training last?

CDL training duration varies by program in California. It typically ranges from a few weeks to several months, depending on the type of license and full-time or part-time training schedules.

What is the cost of getting a CDL?

The cost for a CDL in California includes a $73 application fee, plus additional costs for medical examination, training programs, and the skills test. Training costs vary depending on the school and program chosen.

What disqualifies you from getting a CDL?

In California, disqualifications from obtaining a CDL include serious traffic violations (like DUIs), major at-fault accidents, criminal convictions related to motor vehicle operation, and failing the required medical exam.
