Black box data recorders could be installed in new cars as standard if a Europe-wide study gives them backing.
Police hope the technology would allow accurate crash reconstructions
Police forces across the continent are looking at whether the aircraft-style technology could improve road safety.
The European Commission will use their research to decide if the devices could help in accident investigations.
They are able to record information, including speed and the rate of braking in cars, in the vital seconds leading up to a crash.
It is hoped accident investigators would be able to use the black box information to get a detailed picture of the circumstances surrounding a collision.
Some UK police forces including the Metropolitan Police in London already use the technology in their own cars.
They say it has helped to reduce the number of accidents they have.
The European Commission asked senior police officers across Europe to work on the study looking at the feasibility of installing the devices all new vehicles.
If it is a success, legislation could be passed by ministers in Brussels.
