A study from Graz University of Technology in Austria suggests that up to 17% of crashes can be avoided outright, and up to 25% can result in reduced injury severity, with the use of front brake lights.
FBLs can show whether an approaching driver is slowing down or continuing at a constant or increasing speed. That way, you can make a more informed decision about whether it’s safe to go.
The study recreated 200 real car crashes to determine reaction times, carefully analyzing each step of how the collision took place and when the car/s started braking. Next, they recreated these accidents but added FBLs to cars coming from the front or side, while assuming that the quicker reaction times would apply when these lights are illuminated.
According to the simulations, 7.5 to 17% of the original crashes could have been avoided entirely with FBLs, and as many as 25.5% of those crashes would reduce the severity of injuries, due to the drivers responding more quickly. Even a half-second quicker reaction time can significantly influence the severity of a crash.
