An illustration of how Forward Collision Warning systems work.

Forward collision warning (FCW) systems provide visual, audible, and/or tactile alerts to warn a driver of an impending collision with a car or object directly in its forward path. The Insurance Institute for Highway Safety (IIHS) data show that FCW reduces rear-end accidents by 27 percent. Some systems let drivers adjust the timing of this warning to early, standard, or late.

Forward Collision Warning (FCW): A warning that alerts the driver of an imminent collision in its forward path.

FCW With Pedestrian Detection (FCW-Ped): Detects pedestrians in front of the vehicle and alerts the driver to their presence.

In a recent survey, we asked CR members to rate their experiences with the advanced safety and driver-assist systems on their model-year 2015-2019 cars. Respondents answered questions about their satisfaction with the systems and told us which ones helped them avoid a crash. The survey covered about 72,000 vehicles. See the highlights below.

Which Brands Do FCW Best?

Most satisfying systems, according to CR members: Chrysler, Lincoln, Ram, Lexus
One Chrysler owner shared his experience with FCW and automatic emergency braking (AEB), saying, “It works! I was driving in slow stop-and-go traffic. Something to the right of my Pacifica got my attention and I turned my head to the right to see it. The car ahead of me applied normal braking; my Pacifica emitted a loud verbal warning and applied the brakes as I turned my head back toward the front.” A Lincoln driver explains the impact of an FCW alert, writing, “It is very startling when the lights flash and the alarm goes off. It definitely can’t be ignored!”

Least satisfying: Jaguar, Honda, Acura
A Jaguar driver explained, “It is very difficult to know the real danger. Sometimes it beeps for no reason.” Honda drivers had similar frustrations, with one Ohio owner stating, “It activates too often when there is no need for it to come on.” A common complaint among Acura owners was that their vehicle would issue a visual “BRAKE” alert on the dash, but it wouldn’t bring the car to a stop. This underscores the value of having both FCW and AEB.

CR’s Take: More automakers are making FCW and AEB available in new cars, but these two important safety features are still not standard equipment across the industry. CR believes these systems should come with all trim levels, given their ability to protect and save lives. CR awards extra credit to a model’s Overall Score if it has systems that can operate at highway speeds and detect pedestrians as standard equipment.
