[Mach 1]

I met a cop at a meeting for pregnant wives...lemas classes (spelling)

Anyway, he said its written in the law for them to allow you at least 5 mph over the limit for "speedometer calibration errors", and that most cops will give you 9 or 10 mph over before hassling you, the 9 or 10 mph over is "up to thier discretion", but they have to give you 5 mph.

Of course, this could vary from state to state, but sounds logical enough.

So, I would tell the cop who pulls you over for going 4 mph over the limit that you were going the limit and that your speedometer might not be exactly correct, so why dont you go eat some donuts or something, you fat, lazy, piece of crap..........

you get the idea....
