What test must all drivers who need a CDL take?

All drivers who need a Commercial Driver's License (CDL) must take the general knowledge test as it is a foundational requirement. This test assesses a driver's understanding of the rules of the road, safety regulations, and the various responsibilities that come with operating commercial vehicles. It is essential for ensuring that all drivers possess the necessary knowledge to operate their vehicles safely and legally.

The general knowledge test covers various topics that every CDL holder should know, such as vehicle operation, load management, and emergency procedures. Successfully passing this test is a prerequisite for obtaining a CDL, making it the first step in the licensing process. Other tests, like the driving skills test or tests for specific endorsements such as HazMat, are also important, but they follow the general knowledge test in the sequence of obtaining a CDL. This helps to ensure that all candidates have a strong understanding of basic driving principles before moving on to more specialized skills.
