What is Forward Collision Alert System

Forward Collision Alert is a safety feature built into the car’s windshield, which alerts you to nearby vehicles while driving at highway speeds. The Forward Collision Alert System uses forward-looking sensors to let you know if a Carsh is imminent. It allows you time to avoid a Carsh and prevent serious injuries due to collisions.

As your car approaches slower moving or stationary vehicles at highway speeds, the Forward Collision Alert System emits a warning sound, alerted if the driver does not manually respond by slowing down.

While this might sound like something you’ve experienced many times before, Forward Collision Alert is different because it uses sensors along with cameras and radar technology to figure out precisely how far away the car ahead of you is. If Forward Collision Alert determines that your car will get too close to the one ahead of it within a few seconds, then it sounds an audible alert to let you know there’s potential danger ahead.

It is important to note that Forward Collision Alert Systems are not intended as a substitute for safe driving practices but as an extra layer of protection against accidents caused by distracted or impaired drivers.

How Forward Collision Alert System Works?


When activated, the system will emit a warning chime and illuminate a warning light on the instrument panel if the driver fails to react to visual or audible cues. The Forward Collision Alert System is designed to help alert drivers of potentially dangerous situations. For instance, if there is another vehicle the driver hasn’t seen due to blind spots caused by tall trucks or SUVs. It also alerts the driver when animals or pedestrians are crossing at an intersection ahead.

Most Forward Collision Alert Systems will activate automatically when the vehicle travels over 10mph. They incorporate speed and distance calculations to ensure you are safe on the road. They use radar, cameras, and laser technology to detect objects in front.

Once you install your Advanced Driver Assistance System (ADAS), the Forward Collision Alert System can work with the automatic emergency braking system. The emergency braking system usually applies brakes when a collision is imminent.

Your Forward Collision Alert System can be affected by several factors like weather conditions, darkness, and glare. Therefore, relying on them in situations that compromise their accuracy is not advisable. Check your manual to understand the warnings sent by the system.

Replacing Windshields equipped with Forward Collision Alert System

When it is time to replace your car windshield that is Equipped with Forward Collision Alert System, all the cameras and sensors are removed and reattached after windshield installation. A recalibration procedure is then required to ensure that this critical safety system is functioning properly and is performing in accordance to the manufacturer tolerances.

When your car’s Forward Collision Alert ADAS System is not properly calibrated after a windshield replacement, the cameras or radar can be misaligned by even millimeters. This could cause dangerous driving conditions and accidents!

Many glass shops try to avoid performing recalibration due to lack of knowledge or calibration equipment. They will simply keep the wires intact, install the new windshield and call it done.

When installing a new windshield, be assured that it will always be off by few Millimeters from the original windshield position. This slight shift in windshield position causes the Lane Departure Warning System and the Lane Keeping Assist System to be off.
