What is an AER and How Does It Work?

An Automated Event Recorder (AER) is a small, video-based device that is mounted in a vehicle to record data and events during normal operation. The device continuously records information such as vehicle speed, engine RPM, steering angle, and brake status. This information can be used to reconstruct an accident and help determine the cause. It can monitor driver and passenger behaviors and can be used to improve safety or training programs. AERs record audio as well so it can be used as defense evidence in the event of an accident.

AERs can:

  • Help reduce accidents by providing data that can be used to improve safety programs
  • Monitor driver and passenger behaviors
  • Be used as defense evidence in the event of an accident
  • Improve driving abilities
  • Lower fuel and maintenance costs
  • Reduce long-term insurance premiums
  • Avoid costly litigation
  • Expedite claims processing
  • Save lives and protect assets

Are AERs actually useful in reducing costs?

A recent study showed that driving behavior and accidents of 39 companies over a 6-month period using AER technology; those companies saved an average of 24% on their losses per AER installed. So, for a company with a fleet of 50 vehicles, that’s a claims cost savings of nearly $32,000 per year. This technology is an affordable way to not only improve safety for your drivers but also save your company money.

Are AERs really useful in reducing accidents?

Looking at the number of accidents before and after installing AER technology, the same 39 companies in the study were able to reduce incidents by nearly 10% in just a 6-month period. This is a significant reduction that can save many lives.

Study Details:

  • 50+ AERs in the fleet
  • 4-month installation window
  • A total of 4,928 AERs were installed
  • The most recent claim evaluated was dated 9/30/10, the oldest dated 5/6/06

Rather than simply a camera, it’s an ally in your safety.

The Automated Event Recorder is designed around your need for improved safety. Using dual camera angles that allow you to monitor the driver and the road, this small device is a vital tool in helping your drivers recognize risks and improve their overall driving skills. The AER records changes in driving such as hard braking, swerving and collisions and saves video clips of these events that you can review with your team.

Moreover, an accident can be a costly and stressful event for any fleet, but the AER can help prevent them from happening in the first place. The AER provides concrete evidence of what happened during an accident, so you can take steps to prevent similar accidents in the future. In addition, if a driver is not at fault for an accident, the AER can help exonerate them. The end result is improved driver safety, fewer accidents, and reduced costs from litigation. The AER is an essential device for any fleet that wants to improve safety and save money.

“Recently we were involved in a serious accident. The camera in the tractor clearly showed the other party was at fault in the accident. It is nice to have proof when we are contacted by the other party’s agent.” -John, AER user

“AERs are an excellent coaching tool! Our drivers take pride in returning from a trip with a green light. Coaching using AERs helps our drivers refine their driving behavior. We always recognize drivers with excellent AER scores at our holiday party every year.” -Troy, AER user


Automated Event Recorders are a useful tool for reducing accidents. By providing data that can be used to improve safety programs, monitoring driver and passenger behaviors, and being used as defense evidence in the event of an accident, AERs help save lives and protect assets.
