I've had mine for three years now, and I would really recommend going to a good accredited school. I've been driving trucks for years, but I still learned a lot in the training. It's just like going through regular driver's training, even if you think you can drive really well, driving with a certified instructor will teach you a lot.

Also, make sure that your truck is fully insured, and make sure that if you do get in an accident, your injuries will be covered by Worker's Compensation. If the guy you're working for doesn't have a policy, it would be a good idea to look into taking one out on yourself. My boyfriend has been driving truck for 10 years, he is (or was I guess) an owner/operator, but he leased his truck to the company he was working for. A little while ago he had a very bad accident, rolled his truck and trailers, and totaled them. He badly broke his leg, along with some other injuries, but he's okay. He's lucky that his boss had a WC policy on all of his driver's, so he was covered by that. But he only had liability insurance on his truck, so he's out $200,000 for the truck and trailers. They were paid off, so he at least doesn't owe any money on them, but it will be a long time before he can replace them. It's been a very eye opening experience for both of us. It would have been well worth it to have the truck fully insured. There's a lot of responsibility that comes with driving a truck, and it's often not an easy job.
