About cdltest.com
cdltest.com is a free, independent resource for CDL practice tests and study guides covering every US state and endorsement. We compile content from official state DMV sources and the FMCSA CDL Manual; every question and fact cites its source so you can verify against the original.
Our sources and editorial process
Every practice question, fee, office address, and state rule on this site is compiled from official state DMV handbooks and the FMCSA CDL Manual. Each question cites the page or section of the source material, and every state page carries a full sources list at the bottom — so you can verify any claim against the original.
