The Blue Light System

1. Provides a 15 second warning to drivers
2. Allows emergency vehicles to pass safely
3. Informs emergency vehicles that other emergency responders are approaching

The risk to emergency responders passing through intersections is high.

The Risks:

  • According to the National Highway Traffic Safety Administration (NHTSA) – There are an estimated 4,500 accidents involving ambulances each year.
  • Over a 10-year period, there has been an average of 3,160 accidents each year involving fire trucks.
  • Each year there are approximately 300 deaths in the U.S. that occur during police pursuits.
  • Vehicle Fatality Rates for Emergency Responders are 4.8 time Higher that the National Average.

The Siren is the public’s First Warning.
But Does it Work?

Assume the siren level at 10′ in front of the vehicle is 100dBA.

  • at 20′ it will be 94dBA
  • at 40′ it will be 88dBA
  • at 80′ it will be 82dBA
  • at 160′ it will be 76dBA

Let’s say that you need at least 75dBA of siren level to be audible through rolled up windows and over the car radio.

  • The maximum warning distance you can get with a siren that begins with a 100dBA at 10′ is about 160′.
  • At 30 MPH (44 ft/sec) closing speed, that gives you about 4 seconds of warning for drivers ahead of you.
  • At 60 MPH (88 feet per second) closing speed that only gives you 2 seconds of warning time.

That’s just the warning time for someone to begin to hear a siren, they still have to react and try to locate the emergency vehicle and then do something about it.

If the car has a loud audio system, you’ll needed 90dBA of siren level to be audible inside the car. You only have about 35′ of distance where the siren is loud enough to be heard inside the car.

You’re relying entirely on the flashing lights to warn the kid in the boom car, they likely won’t even hear the air horn.

At 30 MPH closing speed, that’s less than 1 second for the driver to hear the siren and react. At 60 MPH closing speed that’s less than 1/2 a second of warning time.

The Blue Light System is Stand-Alone
it does not interfere or interact with traffic lights systems or controls.

Each receiver has a life cycle of 12,000,000 events.
