Welcome to EO, Sherelyn! You have LOTS of reading to do, if you haven't already, lol, but it's all here, and so are people to help, if you can't find an answer.
I respect your prudence, but would like to say that in the 6 yrs I've been driving OTR, I've never had a moment of being afraid for my safety. (Well, except driving in rush hour in Chicago traffic!)
Most drivers are the type to help you, if they know that you need help, and many of them make me proud to be part of the group. Particularly the expediters!
