California CDL Tanker Vehicles Endorsement Test · Put your knowledge to work in context.
This is an independent study guide for the California Tank Vehicle (N) endorsement knowledge test. It is not a DMV publication. The N endorsement is added to a California commercial driver’s license (CDL) for drivers who operate tank vehicles. It is intended for CDL applicants and holders who need the tank endorsement; the DMV lists Tank (N) among the endorsements a commercial learner’s permit (CLP) holder may carry, with the restriction that tanks must be empty while driving with a CLP and must be purged if they previously contained a hazardous material. The California CDL Tanker Vehicles Endorsement Test case studies are 5 cases and about 2,960 words.
