How to Get a CDL Permit in California
California's commercial learner's permit (CLP) process can mean sitting three separate knowledge tests in a single DMV visit — general knowledge, combination vehicles, and air brakes — depending on the class and vehicle you're training on.
Before your DMV appointment
You'll need a valid noncommercial California Class C license, plus a completed 10 Year History Record Check (DL 939) if you've held a license in another state or jurisdiction within the past decade.
A DOT medical examination is required too, producing both a Medical Examination Report (MER, form MCSA-5875) and a Medical Examiner's Certificate (MEC, form MCSA-5876) that confirm you meet federal physical qualification standards.
Plan for multiple knowledge tests
Class A applicants in particular should expect three written tests in one visit: General Knowledge (50 questions), Combination Vehicles (20 questions), and Air Brakes (25 questions) if your training vehicle has them — all requiring 80% to pass.
Federal rule also requires completing entry-level driver training (ELDT) through an FMCSA-registered provider before any of this unlocks the CDL skills test, for a first CDL, an endorsement upgrade, or a vehicle-class upgrade.
Hold the CLP and complete training
California's CLP is valid for 180 days, with a mandatory 14-day hold before you're eligible to schedule the skills test — use that window to complete your documented behind-the-wheel ELDT hours.
Because DMV procedures and fees can change, confirm the current process on the official CA DMV website before your appointment.
The skills test
Administered at a DMV-authorized location: a pre-trip vehicle inspection, basic control maneuvers, and an on-road driving evaluation.
Pass, and the DMV issues your Class A, B, or C CDL, with endorsements like passenger, school bus, or hazardous materials reflecting whatever additional tests you completed.
