What's inside Delaware Commercial Driver License Manual

At 168 pages, it's a manageable read in one or two sittings.

How it maps to your Delaware CDL knowledge test

The General Knowledge exam is 50 questions at 80% to pass - each endorsement you add has its own separate written test on top of that. Every question comes from this manual, so reading it is step one. Step two is confirming what stuck - the Delaware CDL practice tests on this page pull from the same material and explain every answer, right or wrong, so you find your weak spots before test day.

Key Delaware rules to know before the test

Federal rules ban any handheld phone use while operating a commercial vehicle - that applies in Delaware the same as everywhere else.
