A method for validating an information item regarding a wrong-way driver, which indicates an instance of detected wrong-way travel of a vehicle driving the wrong way. The method includes checking plausibility, in which the information item regarding a wrong-way driver is checked for plausibility, using an additional information item, before the information item regarding a wrong-way driver is made available as a warning message for affected road users. In this context, the warning message is suppressed, if the additional information item characterizes the information item regarding a wrong-way driver as irrelevant.
