Speed humps are good to control rash driving, however, there are more than 100 speed humps in Doha city itself without caution/warning to indicate a speed hump is ahead. This causes injury to drivers and damage to the vehicles for which, neither municipality or public works department will not pay compensation or any sympathy. Some humps will built all of a sudden without any warning. Early morning while going for work no humps on the road and in evening while coming back after jumping the hump only driver will realise that some obstacle is on the road. After many weeks or days or never a caution board will appear. Why not install a caution board prior to making a hump on the road after drawing two or three white cross lines where the hump is intended to be constructed. Most of the speed humps are not scientific type. It is intended to damage the vehicle only. If hump is jumped without warning board, either suspension system or engine crank case or exhaust pipe is liable to get damaged. Who will pay for this damages and struggle to get it repaired? Unwanted humps are made in front of some houses with their influence or without influence. If speed humps are constructed with good intention to control speed, the concerned authorities should install the warning board prior to construction and if any boards are broken or damaged it is to be promptly installed back.
