Summary
  • The forward collision warning system warns you when it detects pedestrians, animals, and other objects moving in your path.
  • Forward collision warning systems use various sensors and provide feedback.
  • Get the most out of your vehicle’s forward collision warning by scanning the road, staying sharp, and being prepared to hit the brakes.
  • Forward collision warning can reduce traffic crashes, protect people on the road, and serve as a driving aid.
  • You can add forward collision warning systems to older vehicles, but the upgrades might not be worth the trouble.

Many modern vehicles come with a variety of driver assistance features, including the forward collision warning system.

In this article, we’ll talk about what forward collision warning is, how it works, and how to properly use it.

What is Forward Collision Warning?

The Forward Collision Warning system is an automotive safety feature that utilizes multiple sensors to detect objects in front of a vehicle. This safety feature alerts the driver when it detects pedestrians, animals, and other objects moving in the vehicle’s path.

How Does Forward Collision Warning Work?

Forward collision warning systems provide visual, aural, or tactile feedback to warn drivers when the system detects an incoming object. Some systems issue warnings using only one of these signals, while others use multiple signals to notify the driver. More systems allow drivers to customize these notifications to their liking.

Not all forward collision warning systems are the same. Some only work at city speeds, while others work at highway speeds. Some systems can accurately detect pedestrians, cyclists, vehicles, and animals at a distance, while others can’t. You’ll need to consult your vehicle’s manual to find out what your system can do and whether it’s paired with other safety features like automatic emergency braking. Forward collision warning can be combined with automatic emergency braking to stop or slow down a vehicle before impact.

How to Use Forward Collision Warning

Some drivers tend to trust their vehicle’s safety features too much and end up forgetting the most basic rules of the road. Even if your vehicle is equipped with the most advanced forward collision warning system, you still have to mind the road and make decisions on the fly. Here are three things to remember when you’re driving.

Scan the Road

Keep an eye out for potential hazards in front of the vehicle. Some systems are less accurate than others when it comes to detecting objects from afar. Small animals might slip under the radar and get hit by your vehicle.

Stay Sharp

You have to pay attention to your surroundings because anything can happen. A pedestrian can come out of nowhere and run into traffic. A vehicle might merge into your lane while you’re driving at highway speeds. You’re more likely to get into an accident if you drive like you’re on autopilot.

Prepare to Brake

Slow down or steer the vehicle to safety if you notice an object in the vehicle’s path. Don’t wait for the system to give you a visual, aural, or tactical warning to stop the vehicle. You should be alert and ready to act to avoid collisions.

What Are the Benefits of Forward Collision Warning?

Driver assistance technology has the potential to reduce traffic crashes and save thousands of lives, according to the National Highway Traffic Safety Administration (NHTSA). The NHTSA recorded 36,096 vehicular deaths in 2019. Human error played a significant role in many of these accidents. Forward collision warning systems are useful, but they shouldn’t be a substitute for a driver’s alertness. Drivers still need to perform the basics when navigating the road to prevent accidents. Forward collision warning systems can be used as a driving aid to improve a driver’s situational awareness.

Can You Add Forward Collision Warning Systems to Older Vehicles?

Yes, it’s possible to add forward collision warning systems to older vehicles. Driver assistance technology like blindspot monitors, backup cameras, and forward collision systems are all available in the aftermarket. But do you really want to upgrade an old car with new technology? Older vehicles are more likely to break down, so you might end up spending more on replacement parts than upgrades. The question you should be asking yourself is this: Is it more practical to upgrade an old car or save up for a new one?
