Does anyone know whether ther is a plus/minus allowance on speedometers plus a %ge allowance when a speed camera is activated or a ticket is issued. My uncle claims he was "done" speeding at 32mph in a 30 zone. I alwyas thought there was a 10% allowance for speedometer calibration plus a discretionary 5mph over the limit before you were given a ticket

EC Community Directive 75/443(97/39) and ECE Regulation 39 lay down accuracy requirements to be applied at the time of vehicle approval for speedometers. These requirements are that the indicated speed must not be more than 10% of the true speed plus 4 km/h (or 2.4mph), and that the indicated speed must never be less than the true speed.

This means that when your uncle was "done" his speedo should have been reading anywhere between 32 and 37� mph, thus offering no excuse for exceeding a 30 mph limit.

In bygone days the police did utilise the 10% plus 5 mph 'rule of thumb' before prosecution but this was before automation i.e. 'safety' cameras, which heralded the cult (and associated purse) of 'zero tolerance' (or as near as dаmmit).
-- answer removed --

The present tolerance level is 10% + 2 m.p.h. Therefore in a 30 m.p.h. area, the level for a fixed penalty is 35 m.p.h. The level for a summons is 50 and the level at which the court is unlikely not to disqualify is 60. More information here.

As mdoo98 says, the payment is a voluntary one and it is easy to avoid it.

I would be very surprised to hear of someone being caught at 32. If you were doing 32 in a 30 you would be behind me. Up to a summonsable speed makes economic time/cost sense if you are a good driver, above a summonsable speed should never be sustained.

At the end of the day though, the law states 30.

please don't take my previous post too seriously!
