Wouldn't there be a margin of error?

It wouldn't be that accurate...They probably add a mph or 2 to the speed if they pull you over while right behind you.

Police car speedometers are periodically certified, just like their radar and laser guns. This means they are tested for accuracy. If they were not, they would be challenged in court every time. In fact, people are forever challenging the accuracy and certification of cop radar and laser guns and speedometers. As you can see, the attempts at challenges are usually not successful. Even if they are, way more people just pay the ticket rather than challenge it. Pacing a car doesn't need to be dead-nuts accurate anyway because there is a range of speeds that will get you the same fine. In California, if you are going anywhere from 1-15 miles over the posted limit, the fine is the same. So it would not matter if the cop was off by a couple of miles an hour, as long as he catches you speeding at all. And chances are you're not even going to get his attention unless you're going at least 5-10 miles an hour faster than everyone else, and everyone else is already speeding anyway, if you hadn't noticed. Try going the maximum legal speed of 65 on the freeway and see how many middle fingers you get for obstructing the flow of traffic. As a side note, if you are stupid enough to let a police car get close enough to you when you are speeding to pace you, then you deserve a ticket. In that case, you should also get a ticket for inattentive driving. And being an idiot.

In many (if not all states), a radar gun isn't required for proving a speed limit has been broken. A visual observation of a speeding driver is all that is necessary, but a radar gun or laser helps.
Radar guns, however, can be calibrated to account for the speed of the police vehicle and adjust as necessary.

If a policeman is "pacing " you his speedometer is reading
the sane as yours, so there is no margin of error unless he
indicates he is giving you a break and tickets you for going
less than you actually were.

MOST DO NOT PACE A VEHICLE FOR SPEED. IT'S NOT AS ACCURATE AS RADAR. YOU HAD TO DRAW HIS ATTENTION TO YOU SO HE RAN 10-28 AND 10-29 VEHICLE REG. AND WARRANTS LOOKED YOU OVER FOR DEFECTIVE EQUIPMENT LIGHTS TAG SO ON THEN STOPPED YOU TO SEE WHAT WOULD HAPPEN. I KNOW I DID IT ALL THE TIME .

Dude its called a radar. They are pacing you to run your tags to see if it is legal or if it is stolen.
