Disclosed is a method for avoiding collisions between vehicles, comprising receiving data that represent a first travel path of a vehicle, the first travel path being a most probable path of the first vehicle, receiving data that represent at least one second travel path of at least one further vehicle, the second travel path being a most probable path of one of the further vehicles, determining whether the first travel path collides with the second travel path and, upon determination of a travel path collision, initiating generation of a signal to warn a driver of at least one of the vehicles of a possible collision with another vehicle. Additionally disclosed is a similar method for avoiding collisions between vehicles, which is executed by a device in a first vehicle. In this method, additionally, a current position of the first vehicle can be detected, and the travel path of the first vehicle is determined on the basis of the detected current position. Additionally disclosed are corresponding server systems and apparatuses in a vehicle that execute the methods, as well as a computer program product, having portions of program code, that can be executed on a processor system.
