Obtaining a commercial driver's license (CDL) is a significant step for individuals looking to embark on a career in the trucking industry. One of the critical components of the CDL licensing process is passing the permit test, which assesses a candidate's knowledge of traffic laws, safety regulations, and vehicle operation. The General Knowledge test is a fundamental part of this process, covering a wide range of topics related to commercial vehicle operation. To help prepare for this test, we've compiled 10 practice questions that mirror the format and content of the actual General Knowledge test.
