Well, there are a number of factors that come into play here. First, if you’re injured, because even a minor car accident can cause injuries, it may be a good reason for you to call the police or ask just for emergency assistance, if necessary.

What if the other party becomes uncooperative?

Another good reason is if one of the parties is not being cooperative or aggressive if they’re not providing you with a driver’s license or insurance. At that point, it might make sense to call the police, especially if they’re trying to dispute what happened or there are witnesses that are uncooperative. When the police show up, they can control the scene and get witness statements that could be very helpful for you later on.
