Doubles & Triples
Practice CDL Test 1
This CDL Doubles and Triples test will prepare you to pass EVERY state’s DMV Doubles and Triples exam. To drive a truck with multiple trailers, applicants must get the Doubles & Triples endorsement. On the official DMV written exam, you must get at least 80% to pass.
The questions on every state Commercial Driver’s License (CDL) official exam are taken directly from that state’s CDL manual. All CDL manuals are based on FMCSA (FEDERAL) regulations, which do NOT change from state to state. Likewise, our practice tests are based on the information in your state CDL manual.
