The person who was following too closely to stop before hitting the car ahead.
you should tell them to be a brain surgeon
The person doing the rear ending is most times at fault unless it can be proved that the other car purpously cut in front of you and slammed on brakes other wise it doesnt matter that they slammed on brakes on purpouse, the following driver is supposed to maintain a proper distance allowing for any sudden stops. Sorry
The person who causes the accident is at fault
Sounds like you rear-ended them. Are you the same person who had the driver ahead "Brake aggressively" a couple of weeks ago? If the front of your car strikes the back of another and they are not in reverse, 99.99% of the time you are at fault.
When the car stops suddenly (like if you slammed on the brakes to try to avoid a collision) inertia keeps the people moving forward. The seatbelt would have slammed into the person pretty hard, and the sheer force would cause the bruising.
It is illegal to repair brakes by an average person take the vehicle to a qualified person.
The person that is responsible for the accident.
Give assistance to any person injured in the accident.
"No, if a person simply drives away after an accident this is considered a hit-and-run. If an accident occurs, even if there are no injuries it is essential that it is reported to the police."
If you were involved in an accident with this person then their insurance information will be listed on the accident report. If you were not involved in an accident then it is not your business who they have insurance with. Much of this is covered by the privacy laws so if you really have to know ask the person.
Momentum! Car has momentum before an accident, this momentum is transferred to the person after the car has made an abrupt stop (accident).
If a person who sues you was the person responsible for the accident, they have little chance of winning the claim. But they have succeeded in scaring you, reducing the chance that you will sue them. It looks like you must counter-claim, and say that you are waiting for the outcome of the court-case on the ticket for the accident. If they are found guilty of causing the accident, no court will hold you responsible for their damages.
