Among other things, a documentation of a crash involving a vehicle is generated automatically. Telematics data is received that has been produced by one or more sensors associated with a telematics device at the vehicle. Based on the telematics data, a vehicle crash period is determined that begins at a start time and ends at an end time of the vehicle crash. Based on the telematics data, one or more metrics are determined associated with the vehicle during the vehicle crash period. Based on one or more metrics, a human-readable documentation of the vehicle crash is generated automatically.

According to one aspect, a vehicle safety system includes an actuatable controlled restraint (ACR) comprising a seatbelt for restraining a vehicle occupant. The ACR is actuatable to control payout and retraction of the seatbelt. The system also includes a controller configured to determine operating conditions of the vehicle and to control the actuation of the ACR in response to the determined operating conditions of the vehicle. The ACR has a normal restraint condition and an enhanced restraint condition, the controller being configured to actuate the ACR from the normal restraint condition to the enhanced restraint condition in response to determining abnormal driving conditions of the vehicle.
