Hi All

 

Noticed various comments over the years about these- even damage & grounding especially for Z'ds!

 

Came across 1999 Road Hump Regulations today- apparently max hieght permissable is only 100mm- trials of different humps only used 75mm!

 

Seen plently higher than this especially in London- if you run foul worth measuring, photographing & taking advice I reckon as they dont have a leg to stand on

 

- What do you all think?

 

Regards

The guys in Leicester should read this, thats speed hump city and they are a lot bigger than 100mm

Excellent piece of research :bow: Armed with this info i'm off to measure the humps on my estate. Fed up of catching exhausts, and we're just about to have a body kit fitted.

They should be removed. They are bad for the environment, I have to take the long way everywhere in south London to avoid them, burning more fuel thus harming the environment un-neccessarily. Then again my car is slammed to the deck.

Just a bit more stirring!= even more interesting, D of Transport recommendations under 1996 regs!;
