speeding camera's,what if you are doing 33 mph

[golf]

i went through a fixed speed camera at 33 mph,are you not aloud to be 10% over the limit,which in this case was 30mph

Afraid not, my son got done last Summer for exactly what you have done, 33 in a 30 limit.
good luck.

no, the speed limit is 30mph and so that is the maximum you are allowed by law to drive at.

youre getting confused with the tolerance of a cars speedo. It may read up to 10% higher than the cars actual speed but is not allowed to read lower than the speed the car is travelling at.

so it is possible that a speedo may say youre traveling at 33mph when in fact the clocked speed of your car might only be 30mph. Of course your speedo may be accurate and you are travelling at 33mph and then youd get a speeding fine.

isn't that a bit harsh I mean cmon even assuming the speedo is accurate, its not a visually accurate thing I trhink we should be allowed up to 33 mph laws are either too tight or too loose

I thought that to avoid the potential for disputes, the authorities operated a policy of (the limit) + 10% + 2mph.
This doesn't mean you can go more than 30mph in a 30 limit, it means the cameras are set to 35mph, 46mph, 57mph, 68mph and 79mph respectively.
This then allows for speedos being up to 10% out, plus 2mph tolerance.

buildersmate - +10% + 2mph is/was indeed the ACPO guideline figure for prosecution of a speeding offence, in operation since 2000 if not before, but it is an entirely separate matter to the maximum permitted over-read of a speedo (for which the similar formula of exists... +10% +4kmh or +10% +2.5mph) which would not help the driver in any dispute.

Imagine if a driver used the over-read as a defence:

PC: Camera says you were travelling at 35 mph.

Driver: What about speedo error?

PC: OK then... 35 +10% +2.5 = 41 mph. Is it your claim that the speedo was indicating 41 mph while driving within a 30 mph zone?

The Police Service now uses technology that enables it to prove that an offence has been committed as soon as a driver exceeds the relevant speed limit by a very small margin. Motorists will therefore be at risk of prosecution immediately they exceed any legal speed limit.

I understand that they can prove that the car's speed was X to a high degree of accuracy. I thought the issue was the accuracy of the vehicle speedo of +/- 10%. Thus it is 'acceptable' to be doing 33 in a 30 limit, because the speedo could be indicating only 30.
Maybe what you are saying is the 'old' +2mph tolerance has been taken away?

Guys - this is simple. The clue's in the question.

Definition of LIMIT: "The point, edge, or line beyond which something cannot or may not proceed".

That's it. Limit. Not guideline, nor target, nor implication.

[kempie]

Speedos do not have a permitted tolerance of +/- 10%... it is + 10% only.

Whatever the speedo reads the car should never be travelling faster than that speed; 10% slower is permitted but 10% faster is not acceptable in law.

In other words, if a speedo reads 30 the car should be doing 30 or less (e.g. 27) because the speedo is permitted to over-read road speed but not under-read.
