I see that a lad on in-line skates was clocked at 50mph in Sussex in an area where the limit is, I believe, 30mph. Sussex Safety Partnerships has said it is aware of the incident but will not be taking action as the speed limits are for motor vehicles. So where does this leave cyclists? Does it mean that unless a speed limit is specifically set for cyclists as well as motor vehicles, cyclists can ride as fast as they like? If that's the case, then I reckon some cyclists who have already been stopped might like to challenge any charges.
Years ago a friend and myself were stopped for speeding in a 40mph limit in Scotland on our bicycles, different laws there though. We were told not to do it again, rather than being fined.
