Nevada CDL — Frequently Asked Questions

How many questions are on the Nevada CDL General Knowledge test?

The Nevada CDL General Knowledge test has 50 multiple-choice questions. You must answer at least 40 correctly (80%) to pass. You have 1 hour to complete it.

What is the passing score for the Nevada CDL test?

80% across the board. General Knowledge requires 40 of 50. Endorsement tests (Air Brakes, HazMat, Tanker, etc.) are 20 questions and require 16 correct.

How much does a California CDL cost?

The government fee for an original Class A or B CDL in California is $100. Skills test retakes are $46 each. These are government fees only — CDL training programs cost significantly more.

What is the minimum age to get a CDL in California?

18 years old for intrastate (within California only) commercial driving. 21 years old for interstate driving, HazMat transport, or carrying passengers across state lines.

Does California accept out-of-state CDL transfers?

Not without retesting. California requires full knowledge and skills retesting for all out-of-state CDL transfers — unlike most other states. If you're moving to California with a CDL from another state, you must complete the full California CDL process.

What is ELDT and does California require it?

ELDT (Entry-Level Driver Training) is a federal requirement for all first-time Class A, B, H, S, and P applicants. California strictly enforces it — you must complete ELDT from an FMCSA-registered training provider before you can apply for a CLP.
