Get Medical Care Immediately -- it is impossible for someone who has just been in an auto accident to say that they have no injuries. Most injuries, especially those that are considered "soft tissue", don't show up until the next day, or even later than that. Not only can failing to seek proper medical care cause a serious injury that is unknown to you to go untreated, but you can compromise your motor vehicle lawsuit by failing to document your injuries. It is critical that you treat with a doctor soon after an accident, and preferably the same day if possible, so a medical record can be created that documents your injuries.

Get Information While Still at the Accident -- because of the confusion that sets in following an accident, many people fail to properly document what happened. Parties to an accident should always exchange insurance information and call for the police to come. Don't succumb to the invitation that you will be contacted later. If you are involved in an accident, demand that the other driver give you his/her insurance information. You should also take pictures of the accident scene in order to document all of the damage to your vehicle and any other vehicles. When the police arrive, try to be thorough in describing what you remember about the accident. 

Contact an Attorney -- you should reach out to an attorney as soon as possible after being involved in a motor vehicle accident. Resist the temptation to speak to your insurance company and provide them with detailed information about your case. Insurance companies may use your words against you later in minimizing your injuries. Allow an experienced attorney to guide you through the waters of filing a claim and securing the best possible settlement for your injuries.
