How Does a Collision Avoidance System Work?

According to the Department for Transport, someone is killed or seriously injured on UK roads every 22 minutes.*

Collision avoidance systems (CAS), are crash prevention safety systems fitted to new vehicles to help improve vehicle safety and reduce serious collisions and vehicle-related fatalities. Find out more about collision avoidance systems, how they work, and how the technology can help fleet and transport managers improve fleet safety.

What is a collision avoidance system?

Collision avoidance systems – sometimes referred to as crash avoidance systems – are driver-assistance systems that use sensors and algorithms to detect potential hazards or obstacles and provide the driver with warnings to help avoid a collision.

How do collision avoidance systems work?

Crash avoidance systems use radar, lasers, or cameras to detect objects or obstacles that may cause a collision. They can monitor for other road users - vehicles, cyclists, and pedestrians- in the normal field of view or driver blind spots . These systems may provide visual, auditory, or haptic (stimulating a touch-based reaction) warnings to alert the driver. The way these systems work varies because while some systems use AI vision technology, others have dash cams to capture images and use GPS to determine location.

Different types of collision avoidance systems

There are quite a few different systems that fleets can utilise to help improve safety; here are some of the most popular.

30+ years of fleet tracking success in the UK

Forward Collision Warning (FCW) Systems

FCW systems monitor your vehicle’s speed, the speed of the vehicle in front of you, and the distance between the two vehicles to warn of rear-end collisions. The forward collision warning system will warn the driver if vehicles get too close.

Automatic Emergency Braking (AEB) Systems

AEB technology automatically activates a vehicle’s brakes when it senses an object approaching the vehicle. While some automatic emergency braking systems only apply a small bit of braking power (allowing the driver time to step in and take over), other systems pump the brakes continually until the vehicle comes to a complete stop.

Lane Departure Warning Systems

Lane departure warning systems alert the driver if their vehicle begins to drift out of its lane. These systems are also useful for assisting drivers with real-time blind spot detection to further reduce the risk of collisions.

Which industries use collision avoidance systems?

Although many industries are using collision avoidance systems, they are currently more commonly used in the automotive, trucking, and warehousing industries.


Collision avoidance systems are commonly used in the automotive industry to provide warnings about potential collisions – or even to automatically brake or steer the car – to help drivers avoid accidents.

HGV and trucking firms

Collision monitoring systems assist HGV drivers travelling long distances to safely complete their routes. Lane-keeping technology, lane departure warnings, adaptive cruise control, automatic braking systems, and traffic alerts can assist on the road. Safety features like cyclist and pedestrian detection and blindspot warnings can help drivers through busy local roads and tight access to loading docks.

Warehousing & logistics management

Collision avoidance systems are used in warehouses to help prevent collisions between forklifts and other objects.

The benefits of crash avoidance systems

Keep your drivers safe

Collision avoidance systems improve the safety and security of your drivers, while also helping them to maintain best safety practices.

Protect others

Not only do crash avoidance systems protect your drivers, but they also help protect pedestrians, other vehicles, and the commercial vehicles in your fleet.

Eliminate the blind spots

With multi-channel cameras covering every angle of a vehicle, your drivers can be fully aware of surrounding and/or oncoming vehicles, which can help them identify and avoid any hazardous incidents before they occur – including rear collisions.

Protect your business

Systems that use video recording can add a highly relevant layer of context if any driving incidents do occur.

Inseego fleet tracking and smart dash cams can augment crash avoidance systems

Whether you're looking to install a CAS in your fleet vehicles, or you already have systems in place, our innovative and leading-edge fleet tracking software and AI dash cams can further improve the safety of your drivers and vehicles.

Powerful AI dash-cams

Inseego AI dashcams can augment collision avoidance systems by providing a video-based context of driving incidents, while also helping to manage risk with First Notification of Risk (FNOR) and First notification of Loss (FNOL) alerts. The technology can alert a distracted driver to correct their behaviour before other collision avoidance systems come into play, as well as an alert when a driver:

  • Uses their phone while driving
  • Eats while driving
  • Doesn’t have their seatbelt on
