Yes! It is important to contact the police immediately if you are involved in an accident. Doing so will provide proof of the accident, and will allow for an immediate investigation of the scene of the accident. In addition, police will take statements of witnesses, and will examine the other driver to check for drug or alcohol use. The police can also be valuable witnesses to your injury at the scene, and they can assist in securing an admission of fault from the negligent driver.
Even in minor accidents, resist the temptation to “keep things simple” by “settling up” with the other driver on the spot. You should make sure that you have not suffered injuries which do not develop symptoms until days or even weeks after the accident, and you should always consult with your doctor and an experienced attorney to make sure that you are aware of all of the avenues of recovery available to you.
