Can my wife sue,the body shop they told us 2 weeks it's been 6 weeks car still not right.ins.. paid 7500 and the car isn't right

A bit more detail would be helpful. However, tell the insurance what was wrong with the repairs. Possibly a letter from an independent mechanic....

Contact the officer and see if he is willing to amend the report.

So I just got an arraignment court summons What does that entail for traffic accident?

It is a plea hearing for you to plea guilty or not guilty. Hire local criminal defense lawyer.

This involves both personal injury and workers compensation issues. Not sure what your question is but seek local counsel that handles both.

Yes you can sue an st fault driver.

Other driver's insurance will not pay for my damages, should I file a claim at Small Claims Court?

You have evidencevto file. But you have the burden of proof to prove your claim.

Should I report an accident if me and another person reversed and hit each other?

Report it to both your insurance and the police.

Sounds like you are at fault if you drove onto the sidewalk. Read your lease about your rights and their duties.

What can I do?

Contact your insurance immediately.

When should I hire an attorney for a hit and run car accident ?

ASAP. Let the lawyer handle the claim and you concentrate on healing.
