The base cost to get your Commercial Driver’s License is in Delaware is $48, but that’s not all you need to make sure your application goes through. Before you go to the Delaware DMV you’ll need to get your paperwork in order and prepare for (at least) the General Knowledge exam. The papers you need are standard by state and include your current valid driver’s license as well as proof of permanent residency or citizenship. For this, a social security card, birth certificate, or green card will do nicely. However, the first thing you’ll need to take care of is your medical exam certification. In order to even apply for a CDL it is required that you get a certification from a licensed medical examiner, as listed on the Federal Motor Carrier Safety Administration (FMCSA) National Registry. Usually these certifications (also known as DOT cards) are good for two years but that can vary if you have a condition that needs monitoring like diabetes or heart disease. Once you have all that in order you are able to go to the DMV to take the exam, but you won’t want to head there without some study sessions first. The 50 question CDL general knowledge exam can be difficult and you only have an hour to finish. If you answer less that 40 correct – you’ll have to come back another day. So, before you go you’ll need to reference the official state commercial driver’s manual and take an extensive number of our practice tests. This DE CDL General Knowledge Exam Simulator has questions that are nearly identical to the real thing and will get you fully prepared. Start now!

Every question we develop is based on the most recent version of each state's official driving manual. Our team regularly monitors each state DMV's website for the latest updates to ensure our practice tests are always aligned with the most current information.
