Here is an all-new California DMV CDL practice test, based on the real general knowledge exam and the official CDL handbook, with 20 multiple choice questions to take you another step closer to obtaining a commercial drivers license in 2021! This California class B practice test covers a broad range of subjects that come up during the real exam: pre-trip inspection, winter driving, driving emergencies, antilock braking systems, skid control, dealing with fires...  We could go on forever, the 2021 California CDL general knowledge test is really quite extensive, with every DMV written test paper being a whopping 50-question challenge.  There is one thing this CDL practice test does not contain and that is questions on air brakes.  The reason behind this is quite simple: air brakes are not covered by the general knowledge test and you must take a separate permit test for the air brakes endorsement, so we have gone ahead and created a separate California air brakes practice test for you! Feel free to sink your teeth into that DMV practice test once you're fully comfortable with these general knowledge test questions.

For those who might have already spent hours looking for a class B California CDL drivers handbook - stop right now.  There is no separate DMV handbook for the class B drivers license, the official CDL drivers manual is the only book you need and it works regardless of the drivers license class you are trying to achieve.  And while we are on this note, let us tell you that there is no such thing as the California class B permit test .  The general knowledge test for a commercial drivers license is always the same, but those who choose to apply for a class A drivers license have to take an additional DMV written test for combination vehicles.  That is the only difference and that is actually a good news, because this means that you can use any California CDL general knowledge practice test without having to worry whether it is applicable to the class B drivers license test!

How much time do you need to spend on this California practice permit test before you move on to the next exam?  The rule of thumb here is that you need to be able to answer no less than 18 of these California CDL permit test questions correctly.  This grade is somewhat higher than the one you are required to obtain at your local DMV office, as you can pass the CDL drivers license test by scoring 80%, but it's well worth creating a bit of a safety cushion for yourself and not to worry about missing one too many questions during the real exam.
