Everyone who drives a big truck and trailer rig has to have a first time. A long, mostly Interstate highway trip is going to be easier than around town. Think ahead when you are driving. Avoid situations where you would have to back up. Avoid situations that might require sudden stopping or swerving. Don’t pass anyone if you don’t really have to, and if you do have to remember the extra length of the trailer back there. You may not always see it in your mirrors.
Let me reiterate: THINK AHEAD
You’ll be fine.
