First accident and it is not small..... Will they fire me?

First...glad your ok, but how don't you know what happened? I would think your company is concerned because you don't know why you hit the guard rail. Not trying to kick you when your down, but I don't want you on the road either if you wreck and don't know why!!

 

Maybe bud...Again, glad you're ok. I do hope you get it figured out, once you do I wish you a long trucking career!!

 

The damage to the inside of the rim looks like impact with something or if it matches the outside damage it’s hard to guess with just 2 pictures. Please stop busting on the newbie EVERYONE has moments of reduced concentration any normal mind wants to wander a bit.

 

Sheared steering arm bolts off at the knuckle. That takes a solid strike with some force.
Note that it looks like the steering arm is still connected to the cross link.

 

Looks like the steering knuckle took out the inside sidewall. Nobody is busting on him, just concerned because he doesn't know what happened.

 

Must have dozed off. You see trucks drift off on to the shoulders all the time. It gets on to the rumble belt then jerk back over. We've all done it. It happens.

In construction zones you can't do that. Gotta be on your best behavior. You won't have any shoulder at all and other trucks will still pass you invariably. You'll feel like a bullet flying down a barrel.
