A collision warning system (also known as a pre-crash system, forward collision warning system (FCW), or collision mitigation system) is an advanced driver-assistance system designed to prevent or reduce the severity of collisions. Let’s explore how it works:

1. Function:
   • The collision warning system acts like an ever-vigilant guardian angel, watching for potential trouble.
   • It provides visual, audible, and/or tactile alerts to warn a driver of an impending collision with a car or an object directly in its forward path.
   • The system detects a potential collision with a vehicle ahead and alerts the driver.
   • Some systems also include pedestrian detection, warning the driver if a pedestrian is in front of the vehicle¹²³.
2. Interaction with Automatic Emergency Braking (AEB):
   • Although the collision warning system will not automatically stop a car, it often works in concert with automatic emergency braking (AEB).
   • If the driver does not respond in time to the warning, AEB will automatically apply the brakes to prevent or mitigate a collision.
3. What to Look for:
   • When buying a car, especially if it’s a used model, check to make sure it has both FCW and AEB.
   • Some automakers use similar names for both systems, which can be confusing.
   • Look for systems that allow you to adjust the timing of FCW (early, standard, or late) to suit your preference.
   • Automakers are committed to making FCW and AEB standard in new cars beginning September 1, 2022, but some models still lack them as standard equipment¹.

Remember, collision warning systems enhance safety by providing timely alerts and assisting drivers in avoiding potential collisions
