sideswiped by a 18 wheeler?

You have a lot of blanks in your question, if you say you called 911 and they didn't even give him a ticket, what's that mean? did the police stop the truck driver and conduct a traffic accident investigation?

If they stopped the driver of the truck and conducted a traffic accident investigation and did not issue any citations, it means a report of the accident was made, and the officer was unable to determine who was at fault, as I'm sure finger's were pointed in both directions. It would be a he said, she said and without witnesses, it would be a insurance claim adjusters problem.

Report the accident to your insurance company and let them do their job.

Not much you can do except let the insurance companies fight it out.

I would advise the next time a tractor trailer comes up on you like that, don't slow down. If anything speed up and get the he77 out of the way. I know they tell you in driving school to slow down and let them pass, but in order for someone to pass you, they have to have a clear lane to pass in. That was not the case as you, yourself stated.

I see it all the time, in most states trucks are not allowed in the left lane on a 3 lane road, but a car that is allowed in the left lane will just sit there in the center lane to mess with the truck driver. By doing so, you are putting your life in the hands of the truck driver. After the fact the car driver wants to complain about what a bad unsafe driver the truck driver is, If he's such an unsafe driver then why would you put your life in his hands by just driving along or hitting the brakes when you feel he is too close.

A tractor trailer can crush any car on the road like it is a bug. A car accelerates ten times faster than a tractor trailer at any speed and has the capability to get out of the way. Most drivers, however will not get out of the way, it's more fun to try to induce road rage and put everybody around in danger. Trucks take at least 3 times the distance to stop as a car and have blind spots on all sides of the vehicle including 10 to 40 feet directly infront of and behind.

The next time something like this happens, just get out of the way. I know it's not fair and all that garbage, but in a wreck the truck is going to win every time as far as damage and personal injury goes.

The best thing is to take the services of legal attorneys. I was also encountered with the same situation and then I decided to hire http://teftellerlaw.com./ They fight for me and at last I got justice due to these legal attorneys.
