Depending on the type of training you want to learn, there are two parts to truck driving school. There is a physical set of skills you will learn, followed by a mental evaluation of your acquired skills.
It’s a truck driving school, after all, so you should expect lots of cab time. Soon you’ll be driving, and your driver training is going to be in full swing. Driving is the physical part of the work, the core of your truck driver training, and something you will continue to adapt to as conditions change in the industry throughout your career.
The other part of your job is the psychological part, and you should expect a great deal from your truck driver training: to learn about the rules and regulations governing truck drivers on and off roads. They are, of course, linked to the job of driving a truck, but you will be taught the rules and regulations separately.
