In addition to the legal consequences, reporting an accident that is your fault can also be important for practical reasons. If you do not have insurance, you will need to pay for any damages that you cause. By reporting the accident to the police, you can create a record of the incident that could help you in the event of a lawsuit.
It is important to note that reporting an accident that is your fault will likely increase your insurance premiums. However, it is still important to report the accident, even if it means you will have to pay more for insurance in the future.
