Test, required for a commercial learner permit, consists of 50 questions, where 80 percent of questions must be answered correctly to pass. The CDL Skills Test must be passed for the applicant to obtain their CDL license. It includes three different sections: The first is the Pre-Trip Inspection where the applicant must inspect their vehicle what they would inspect and why. The second is a written test on highway safety and a test about different parts of a truck with a minimum of 30 questions on the test. To pass this knowledge test, student drivers must answer at least 80 percent of the questions correctly. The third is a driving skills test. To pass the driving skills test, the student driver must successfully perform a set of required driving maneuvers. The driving skill test must be taken in a vehicle that the driver operates or expects to operate. For certain endorsements, such as air (pneumatic) brakes, the driving skills test must be taken in a vehicle equipped with such equipment. If the test is done in a vehicle equipped with an automatic transmission, a restriction of E will be placed on the license prohibiting the driver from operating a vehicle with a manual transmission. The student driver also needs to show they do in fact show the characteristics of an aware and fully operative driver. This does not exclude certain disabilities; however, standard requirements required by the safety operators must be met. Employers, training facilities, states, governmental departments, and private institutions may be permitted to administer knowledge and driving test for the state. The test must be the same as those given by the state issuing the CDL, and the instructors must meet the same professional certification as state instructors. States are required to conduct an inspection of any testing facility and evaluates the programs by taking an actual test as if they were testing driver at least once a year, or by taking a sample of drivers tested by the third party and then comparing pass/fail rates. In addition, the state's agreement with the third party testing centers must allow the FMCSA and the State to conduct random examinations, inspections, and audits without notice. Medical certification In 2014, the law regarding drivers in pursuit of a CDL was modified and requires a DOT medical examiner to authorize a person with a medical issue to be able to drive. Prior
