This is especially true if you inexperienced.
Regarding your truck driving job, you can ask the other experienced truck drivers to teach you a trick or two about the free CDL training.
Having said this, it is not always enough to learn the regulations of FMCSA, SAFER or OSHA and respect them.
To put it in a different way, everything needs a little push, a trick, or a strategy.
Therefore, it is always best to talk with someone to guide you through a particular process or teach you how to start.
For example, if you have a trucker friend on the road who has a previous experience, you can definitely learn a lot.
As an illustration, one of the best ways to get involved in something while inexperienced is to ask someone experienced.
Generally speaking, it is like starting your career already experienced.
