Speeding tickets: how often must a cop car's speedometer be calibrated

i would guess 'never.' you'd have more luck trying to get his dashcam footage and prove he never actually met the requirements for 'pacing' (i think it varies between states), since they often just drive on the interstate (prolly speeding themselves) and pull over anyone who 'looks' like they were going too fast. they do it all the time around here, except the time i got caught by an unmarked car already underway, the douche had the gall to actually say he radared me.

if they won't supply the dash cam footage, you should try and have the ticket thrown out on the grounds that they wouldn't supply you with available evidence to defend yourself.

Justice would dictate a speed limit of around 150mph.

Since clearly Justice is not being served here (only someone's wallet, and it's not yours), fight it to the death!

Next time, a Passport from Escort would be a good investment.

It's likely that it's been determined/ruled before that, as long as the speedometer in a cop car is functional, it is accurate.

Dunno though, just a guess. I have no idea what type of speedometer system the cars typically used in law enforcement have, or if it's any different from the civilian model.

You would probably have more luck trying to argue a tire size angle, but they could probably prove that with maintenance records, lol.

I agree that pacing overall is nonsense though. Perception is hardly reliable when it comes to something like that.

So by your standard, no dash cam = no crime? Yeah, the judge is going to right along with that.

As for the OP, generally speaking, the speedometers should be calibrated annually or anytime they change out the wheels or tires on the vehicle. Don't expect to get your ticket thrown out just because you think the speedometer was off either. Best of luck to you, but I recommend just paying the ticket.

Go to court, plead not guilty. Waste more of their time and money than they would ever get from the ticket.

I tell the prosecuter exactly that before it even goes to court (usually via email). I just say if they do not offer a continue for dismissal, we will just waste everybodys time and money... Every single time they drop the charges.

I've met my quota for parody threads for the week.

Someone make "Jaywalking ticket: How often does a cop have to have his eyes examined?"

You talk to a prosecutor over a traffic ticket?

No

You are a liar.

how fast were you going was this a 71 in a 65 for a 85 in a 65 type ticket?

I do know they have to calibrate their radar guns before and after their shift. If you can prove they didn't calibrate then off the ticket you go. But good luck in getting that without video.

funny thing, we actually had this constitution thingie and it was law that people were considered innocent until they were proven guilty beyond a reasonable doubt.

but somewhere along the line we apparently set the precedent that as long as it's a minor infraction, cop's word = gold.

So until the invention of the video camera, everyone was innocent? Because nobody ever lies and says they're not guilty when they really are...

Negative, ghostrider. Test does not mean calibrate.

Semantics, really, but still. ;)

Ours are calibrated at the factory and then pretty much never again. For my car, I have radar and GPS in the camera, both of which agree with the speedo. Considering my car has been through a cement wall(wasn't me driving thankfully) and it's still accurate I would say it takes quite a bit to knock one out of calibration.

i didn't ever say out judicial system used to be better than it is right now. just that certain laws are often ignored because of some (possibly imaginary) far-reaching precedent.

no, absense of DNA evidence did not exonerate all murder and rape defendants from fifty years ago, but they were still subject to a fair trial and judged based on the 'reasonable doubt' principle. i'm saying that things like minor traffic violations have somehow escaped this rule, allowing a police officer (and i'll avoid getting off on a 'all cops are idiots with dick issues' rant here, i'll just mention that 90% of them are in fact lying cunts) to basically convict someone of a crime on the spot by writing a ticket. your 'fair defense' can include video footage, training records, calibration records for a radar/laser gun, et al. but there's nothing you can do to actually question the word of the officer, i.e. he said he radared me and i know he obviously didn't. and that's a big pile of pigshit. pun intended.

Don't listen to all this nonsense. ANYTIME a police car is used to pace another car for the purpose of issuing speeding tickets, the speedometer MUST be calibrated at least every 1000 miles.
Failure to provide the necessary documentation on the calibration specs, testing protocol, and frequency is an automatic dismissal of the speeding ticket.

Just remember to demand such proof when you take this to court. It's highly unlikely that they'll have it in hand, and your ticket will be dismissed on the spot.
Do NOT let the prosecutor or judge try to persuade you that it's not the law...remember, they both work for the same side as the cops...you MUST stand your ground in a stance of dominance to persevere.

Everyone knows this.

Every 1,000 miles would be about every 10-15 days or more based on average usage of a patrol vehicle. Shit, I've put 183 miles on a car in an 8 hour shift and never gone above 50 miles per hour.

So, I hope this is a badly veiled joke of some kind or laced with some kind of sarcasm. If not, I'd like to see some legal evidence.

Is you stupid, boy?

The evidence is on the internet. Look it up.
Always remember, if you read it on the internet...it must be true.

Like it or not, and clearly you don't, the word of a law enforcement officer does carry a different kind of weight in a court of law. That is the reason they are subjected to a more stringent hiring practice, a more strict set of rules governing their continued employment, etc.

Don't let some bullshit media bias where only the worst of the worst situations are covered constantly skew the fact that there are millions of police officers that are honest, hard working people of integrity as compared to the couple dozen a year that are compete fuck sticks.

This is how it will roll down in court:

You: "I have the following evidence that I wasnt speeding (proceed to show video evidence of yourself not speeding, failure of the cops radar gun, no calibration of the patrol cars speedometer, etc)"

Cop : "DEERRRRRPPPPP I poop my pants!"

Judge:" I agree with the cop, guilty."
