I am glad you stated this. It's something that I try to tell the new truck drivers about.
Well, we live and learn. Look like you did just fine, of course you still didn't do the worse.
Too often guys jump company to company burning bridges, lol. They never get the change to quit cause they are fired everywhere, man that is the worse.
New drivers, listen up.
Do your research first, decide what you want from a company so that you go to the one that will serve your needs for as long as possible. It will help you to get the best job when you really see something you like.
