http://www.sustrans.org.uk/assets/files ... alming.pdfThe above link gives the dimensions of speed cushions
A few years ago my daughter damaged the underside of her sports car going over a cushion at the correct speed
The local highways refused to pay for the damage so her husband and myself went out and measured the cushion
What we found was that this and many others were over the maximum allowed height, over 50% of those measured to be precise
The highways then paid for the damage, after being threated with a small claims summons.
A few weeks later many local cushions were dug up and re laid at the correct height.
If any local cushions are causing problems get the measurements checked against the above link
This is another case of local authorities ignoring the the rules and regulations laid down for the benefit of everyone
Remind you of anything???????
