Front-facing brake lights could significantly prevent road crashes
- A new study led by Ernst Tomasch at Graz University of Technology suggests that adding front-facing brake lights to vehicles could reduce collisions by up to a fifth.
- The study, published in Vehicles, used real-world crash data and accident reconstructions to demonstrate the potential impact of forward-facing brake lights.
- Front brake lights could provide oncoming or crossing traffic with a visual signal, reducing reaction time and improving safety at intersections.
- Only limited field tests have been conducted on front brake lights, such as one in Slovakia, making the Austrian study particularly significant.
- Analysis based on accidents from Austria's Central Database for In-Depth Accident Study showed that 7.5 to 17 percent of collisions could have been prevented with front brake lights.
- In some cases, the front brake lights could also decrease the impact speed and lessen injuries by up to a quarter.
- Front brake lights, illuminating green instead of red, can be retrofitted into vehicles at a relatively low cost, offering a potential safety improvement.
- However, the effectiveness of front brake lights depends on the visibility to other road users, with recommendations to consider side placements to enhance their impact.
- The researchers advocate for further trials and implementations of front and side braking lights to enhance vehicle safety design.
