CDS Tractor Trailer Training offers CDL Refresher Courses for drivers who have been away from the industry for a while and need the training to help bridge the gap from when they stopped driving. A student must still hold their CDL in order to be accepted into the course. Refresher Training lasts 40-hours and includes a customized program based on individual driver’s needs. Most companies require 40-hours when a driver has been out of a truck or out of training for a year or more. This course will refresh your skills in shifting, backing, and other road skills.
