Guidance for § 391.31: Road test.
Question 1: Are employers still required to administer road tests since all States have implemented CDL skills testing?
Guidance: The employer may accept a CDL in lieu of a road test if the driver is required to successfully complete a road test to obtain a CDL in the State of issuance. However, if the employer intends to assign to the driver a vehicle necessitating the doubles/triples or tank vehicle endorsement, the employer must administer the road test under §391.31 in a representative vehicle.
Question 2: How does a student enrolled in a driver training school comply with the requirement to pass a road test?
Guidance: The road test is administered only after the student has demonstrated a sufficient degree of proficiency on a range or off-road course. A student who passes the road test and is qualified to operate in interstate commerce could cross a State line in the process of receiving training.
Question 3: May a carrier use a blanket certification of road test for specific vehicles (driver’s names, etc., left out)?
Question 4: May a motor carrier designate another person or organization to administer the road test?
Guidance: Yes. A motor carrier may designate another person or organization to administer the road test as long as the person who administers the road test is competent to evaluate and determine the results of the tests.
