Going to school to get a commercial driver's license isn't a requirement for the license in all states. However, trucking schools provide instruction that can help a person learn the laws and practice driving, and it can have additional benefits.
Truck driving training programs do give people certain advantages. Students in these programs learn how to shift gears. Some training programs include instructions that can help test takers to get special endorsements, such as an air brake endorsement or a double trailer endorsement. Some people might also qualify for insurance discounts if they obtain a Certificate of Completion for a truck driving program.
