do I have a chance....

i am a newbie whose career may be over after only 5 months...
I drove for a company that does not have a good rep, (has about a 100% turnover rate, which tells you a lot) but, i was new out of school and not real smart about choosing. Anyway, I had 3 incidents within about 5 weeks.
Now, of course, nobody wants to hire me. I want to know if I have any chance at all with anybody or am I finished. My MVR is clean.

Here are the 3 incidents:
* Backing - Barely touched a car fender in a parking lot. There was no damage, no injury, no ticket, just enough contact to call it contact. It could have easily gone unreported, probably should have, but I was trying to follow the rules and do the right thing.
* Took out some guardrail - Followed company directions and confusing signage, but found myself on a very narrow, curvy road. This was definitely not the kind of road an 18 wheeler needed to be on! Before I could find a place to turn around, I found myself way too close to the guard rail and ended up taking out a section of guard rail. The policeman that helped out told me they had had similar problems many times because the sign for the road was not clear and did not issue a ticket.
* Tore off trailer door - The chain holding the trailer door came off and when I pulled out of the dock, the door was ripped off the trailer.

I take full responsibility for these incidents, but they are all rookie mistakes. Is there not any company that will give me a chance now? Does anyone have any suggestions?
