Yes! Absolutely, no doubt about it, every time. If you are involved in a motor vehicle accident, call the cops. They may be too busy to come out to the scene, or they may not think the accident merits police involvement, but that doesn’t mean you shouldn’t call.
Cops can assist in the following ways:
1. Sometimes the other driver is hostile and irritated, possibly even drunk or otherwise under the influence. In these situations, it may not be safe to approach this person. By calling the cops and allowing them to deal with this person, you keep yourself safe.
2. Sometimes the other driver tries to leave the scene of the accident, in order to avoid liability or for other unknown reasons. By calling the cops, you increase your chances of tracking down this person. Without getting his information, you (generally) have no claim.
3. Sometimes the other driver provides false contact or insurance information, in order to keep you from making a claim against him. On your own, you simply have no way to know whether they are who they say they are, or whether the information they are giving you is accurate and up-to-date. The other driver is much more likely to be honest with an officer, and the officer has ways of verifying the information.
4. When police come out to the scene of a motor vehicle accident, they are required to make a report of the incident. This report not only provides the information necessary to make a claim, but also serves as proof that an accident occurred, as well as provides the details of the accident.
5. The police may take photographs of the scene and/or the damage to the vehicles. These pictures will later be helpful in a claim against the other driver.
6. The police may help track down witnesses that otherwise would have been lost.
7. As an added bonus, the police will likely issue a traffic citation to the other driver.
