Minnesota CDL Hazmat — What to Expect
In Minnesota, the CDL Hazmat (H) endorsement is issued by the Minnesota Driver and Vehicle Services (DVS), Department of Public Safety. The Hazmat knowledge test is given at Minnesota DVS exam stations, with the TSA security threat assessment completed separately through IdentoGO.
The knowledge test has 30 questions and requires an 80% passing score — at least 24 correct. The exam is based on the federal FMCSA regulations under 49 CFR, which are the same in all 50 states, so the study material does not change from state to state.
Before the H endorsement can be added to your Minnesota CDL, you must pass a TSA Security Threat Assessment (background check), about $86.50, at an authorized enrollment center — processing takes 2–4 weeks, so apply early.
Endorsement fee: Varies — confirm with Minnesota DVS. Retake wait: Varies by office.
