It will be handy to have an accident details recording app installed on your smart phone prior to any accident. Bear in mind that your device may be damaged in the accident, therefore also make sure you have a pen and paper stored in your glove compartment (cubby hole).
Take down the following details. Before installing an app, make sure it has provision for the information required in the list below:
3rd party:
Personal Info:
Identity number.
Street Address.
Home and Cell numbers. Call the cell number straight away to make sure it is correct.
Owner info as above if not that same as the driver.
Insurance details.
Vehicle info:
Make.
Model.
Color.
License plate number.
You will need to give the other party your same info.
Witnesses:
Same info as for the 3rd party personal info.

Badge Number.
Police Station.
Get a copy of the police report.
