It's important to report an accident to the police as soon as possible, as this will help ensure that the accident is properly documented and that any necessary investigations can be carried out. In some jurisdictions, failing to report an accident within a certain timeframe can also result in penalties or legal consequences.
If you are unsure about the timeframe for reporting an accident in your jurisdiction, or if there are any special circumstances that may apply, it's best to contact your local police department or the relevant government agency for guidance.
