Are you studying to become a commercial driver in San Diego, San Francisco, Los Angeles or another part of California? If you ultimately hope to drive large Class A vehicles pulling two or more trailers, you will need to add a California doubles and triples endorsement to your main commercial driving license. The CA doubles and triples practice test for 2021 we provide here on can whip your knowledge into shape ready for this DMV written test! Class A vehicles with double and triple trailers are among the heaviest and most challenging vehicles to drive; consequently, obtaining a learners permit is not as easy as it would be if you aimed to drive a taxi, box truck or similar low to medium weight commercial vehicle. You should only begin using our doubles and triples endorsement practice test once you have dealt with the CDL general knowledge permit test and any mandatory endorsements for this vehicle type. Not sure what these endorsements are? Don’t worry – we are here to help!

Having passed the CDL general knowledge DMV permit test in California, the temptation may be to jump straight to studying for your doubles and triples permit, otherwise known as a “T” endorsement. In fact, there are a couple of other CDL CA practice test quizzes on our website which you will need prior to this doubles and triples CDL practice test. All double and triple trailer vehicles qualify as combination vehicles, with single trailer vehicles being their smaller counterparts. Therefore, all aspiring drivers of double and triple-trailer vehicles must take the California CDL combination test for a Combination Vehicles endorsement to obtain basic knowledge about managing this vehicle-type, before moving on to the more specified T endorsement. The Air Brakes endorsement is also mandatory for double and triple trailer vehicle operatives, as all combination vehicles are fitted with air brakes. Consequently, it is advisable to get this endorsement DMV test under your belt too, before moving on to study for your doubles and triples exam with this Class A license California practice test.

If you still need to pass the Combination Vehicles endorsement exam, we recommend spending some time working with our alternate California combination CDL practice test to get you through it.
