Is it true that motorcycles could slip on 360-degree tempered glass road studs (a.k.a. Cateyes)?
Some customers and road users may ask: Would 360-degree tempered glass road studs affect the safety of motorcycle riders? Would motorcycles slip on 360-degree tempered glass road studs?
The following video was taken on a road in one southeast Asian country. The 360-degree tempered glass road studs have been installed for several years in this section. As the video shows, this is a high traffic area.Many motorcycles ride over lane lines as well as the 360-degree tempered glass road studs, but no one slips or falls.
After being installed on the road, the protruding part of a 360-degree tempered glass road stud is a dome shape with a diameter of 60 mm and a height less than 25 mm – to be more precise, the height of SIG-25 is not 25 mm but only 22 ~ 23 mm, and the height of SIG-19is not 19 mm but only 17 ~ 18 mm. In the case of a plastic road marker which is also commonly used, the protruding part is a square of 100 mm on each side and a height of 18 mm. We can see clearly that the protruding part of a 360-degree tempered glass road stud is smaller than that of a plastic road marker.
There is once an urban legend indicating that 360-degree tempered glass road studs could cause motorcycles slip and fall. However, we have never found a country compensation case that was originated from a traffic accident caused by 360-degree tempered glass road studs.
