Nevada Licensing and training Test 2

A first-time hazardous-materials endorsement applicant passes the knowledge test. Is that score alone enough to establish security eligibility for the endorsement?

Correct answer: No. The applicable federal security requirement must also be met.

Knowledge and security eligibility are separate requirements. Current federal law provides for the applicable TSA determination or qualifying valid-TWIC alternative; an employer check or an intrastate trip is not a substitute.

A driver holds the proper CDL class but has an L restriction. May the driver operate that class of commercial vehicle with air brakes?

Correct answer: No. L prohibits operating an air-braked commercial motor vehicle.

Vehicle class and equipment restrictions are separate. Appropriate qualification and restriction removal are needed before the driver operates an air-braked CMV.

An applicant takes the CDL skills test in a commercial vehicle with an automatic transmission. Which equipment restriction normally results?

Correct answer: An E restriction prohibiting manual-transmission commercial vehicles.

The E restriction results from using an automatic-transmission CMV for the skills test. Transmission, air-brake, and intrastate restrictions concern different qualifications.

A driver is qualifying for a school bus that requires a CDL. Does obtaining the school-bus endorsement eliminate the passenger-endorsement qualification?

Correct answer: No. The driver must qualify for the passenger endorsement as well as the school-bus endorsement.

The P and S qualifications are complementary. Federal school-bus endorsement requirements include qualification for the passenger endorsement; earning S does not replace P.
