Frequently Asked Questions
What is the California CDL tanker endorsement?
California uses the Tank Vehicle or N endorsement for qualifying CDL vehicles that haul liquid or gaseous material in attached tanks. California DMV Section 8 says the cargo does not have to be hazardous material.
What tank size requires the N endorsement in California?
California DMV Section 8 uses the threshold of tanks with an individual rated capacity of more than 119 gallons and an aggregate rated capacity of 1,000 gallons or more, permanently or temporarily attached to the vehicle or chassis.
What score do I need to pass the tanker knowledge test?
Federal CDL rules in 49 CFR §383.135 require at least 80% correct on each knowledge test. California DMV administers CDL knowledge testing under those federal standards.
Does the California tanker endorsement require ELDT?
FMCSA ELDT applies to first-time Class A/B applicants, Class B-to-A upgrades, and first-time School Bus, Passenger, or HazMat endorsements. Tank Vehicle (N) alone is not listed as an ELDT-triggering endorsement, though ELDT may apply to your underlying CDL class or other endorsement path.
Can I drive a loaded tanker with a California CLP and N endorsement?
No. California DMV states a CLP holder with an N endorsement may operate a tank vehicle only when it is empty. If the tank previously contained hazardous material, it must be purged.
