Personal — no signboard or speed breakers

As we stay in goregaon there is a school name as st johns school, there is no sign board of school ahead or speed breakers, as there are smaill kids going to school and it is on main sv road, atleast the drivers who are driving should know that the school is ahead or any sign board and speed breaker so that they slo down.
The bike riders and other vehicle go in such a speed, many a times the kids are hurt due to rash driving.
Request to kindly look in to the matter.
