Method and arrangement for subsequent analysis of processes in a motor vehicle where a safety device in the vehicle has not triggered and includes a control device for the safety device and a sensor for detection of processes which can result in that the safety device is triggered if a first parameter exceeds an upper limit. With such arrangements, a document can be directly inserted into a document sampler without an extra step of swabbing a document with a sample collection device. An emergency service provider may remotely activate the monitoring devices in the user’s vicinity upon receiving an emergency help request from the user, and receive the information sent by the monitoring devices to enable the service personnel to plan appropriate response to the emergency at hand.
