You'll be fine. I've had several incidents when backing where someone will hop out and scream at me that I'm going to hit their chruck, or honk as if I'm going to hit them. It's so much fun to prove the wrong, after they insist you stop doing what you're doing.

Also, be very careful. Instead of helping or being kind, when you drive for them, all anyone will do is whip out their phone. Happened to me with a poorly labeled worksite at a truckstop in NC a week or two ago. One guy did actually let me know I was being dumb, and I thanked him and I ended my already long day normally instead of on YouTube.

And, be prepared to get kicked out of perfectly legit places too. "We don't want Swift trucks here" and "Swift is banned from this lot". There's even state run rest areas that banned Swift trucks (I don't think it's legal but who's going to fight it?) Also be prepared for super truckers to scream at you over the radio for driving like an idiot when something perfectly normal happens, or for them to move half a lane over to pass or be passed.

But, I will say, it makes life so much easier when no matter the situation, someone will help you back in somewhere, and people will actively avoid you lol.
