Speed bumps are set on the load near at school and street with
lots of pedestrian to ease down the speed of cars. However,
no matter car drive fast or not, the car always trip on speed
bumps, and it gives stresses to drivers and damage cars.
‘S line stopper’ solve the problem of existing speed bump to
accommodate to low speed drivers. When the low speed car goes
through two lined block of new designed speed bumps, the car can
miss the speed bump. But high speed car definitely meets
two blocks of speed bumps by S-line system.
