A collision warning system and method for a motor vehicle. A measuring device in the vehicle is provided for measuring the distance dx to a second vehicle traveling ahead, the distance signal being delivered to an evaluation device in the first vehicle. The evaluation device continuously calculates a deceleration a<SUB>subject vehicle demand</SUB>, which is applied by the vehicle after expiration of a driver reaction time T<SUB>reaction </SUB>in order that a remaining distance dx<SUB>remaining </SUB>to the second vehicle traveling ahead can be maintained. If a<SUB>subject vehicle demand </SUB>exceeds an instantaneous deceleration that can be achieved by an adaptive cruise control ("ACC") system, a system limit warning is transmitted, prompting the vehicle driver to brake with additional appropriate force. If a<SUB>subject vehicle demand </SUB>exceeds an assumed vehicle deceleration that can be generated by braking on the part of the driver, a collision warning signal is transmitted independently of the ACC system.
