On roads that have speed bumps or humps, cars must press on their brakes to safely travel over each obstacle. Each time the brakes are pressed, the brake pads release small metal particles.
According to Yahoo News, a study by scientists at King’s College London has revealed that these particles are making people sick. Specifically, the study confirms that the particles not only contribute to coughs and colds, “but could be a factor in more serious illnesses like pneumonia or bronchitis.”
The dust created by brake pads is being compared to fumes given off by diesel exhaust and can even account for “up to a fifth of fine air pollution particles, known as PM2.5, at roadsides.”
Several sources have been calling for a removal of all speed bumps and humps as far back as 2016 over air pollution concerns; these new findings are adding momentum to the effort.
For communities who want to slow drivers without the increase in air pollution that speed bumps and humps bring, Radarsign has a variety of products that can provide a solution. Driver feedback signs help to slow cars down by reminding drivers about the posted speed limit without forcing them to hit the brakes repeatedly.
