I have also verified my speed by holding it constant for 1 mile and using a Tachymeter.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Does anyone know of a place in Virginia (preferably Northern Virginia) that will calibrate and certify my speedometer reading?
I got speeding ticket and was told that having your speedometer checked, and showing up in court with documentation saying your speedometer was off is very common. I'd like the calibration to show it's 4 mph too low . . .

Good luck. German laws require that speedometers are optomistic, and while there is no such law in the US, the German manufacturers don't care to have to assembly processes and just make them all optomistic. You'll likely find that it reads at least 2mph higher than reality.
If you are a AAA member, you can call the office and find out when their traveling speedo checking system will be at a location near you. I did this many years ago so I am not 100% sure they still do it, but it was a great service.
There are a few authorized shops that do the speedometer calibration. I think the list is on the DMV website. You have to use an authorized shop and get a certificate for the court. My lawyer (last time I got a ticket) gave me the name of a place in Fairfax. I will try to dig it up in the Rolodex tomorrow. FWIW, my speedometer was actually a couple of mph faster -- WRONG DIRECTION -- so it showed 78 mph at 75 mph.
Speedometer accuracy is a function of tire inflation and/or wear.....
Same problem with the officer's car, speedometer "head" can be bench calibraded but that doesn't account for inaccuracies as installed, and throughout the day as the tire heat and expand due to pressure increase.
Unfortunately, I know my speedometer reads high. I'm looking for a place that might be uhhh . . . driver friendly. Anyone can send me a private message if they want. Thanks.

Sorry buddy, but I was told that the court (Fairfax) will only accept calibrations with certificate from authorized shops.
You might try to have a "friendly" independent mechanic to sign an affidavit that there was something wrong with the car (eg. wrong tire size, malfunctioning ABS system which can affect the speedo, etc.) but I would just get a lawyer, plead it down from reckless to speeding, take the points, then attend driver improvement to get rid of 2 of those points.
Good luck.
Yeah, I wish . . . My driving record, which only goes back 10 years in DC, was spotless before this ticket. I hope to keep it that way
I am pro law enforcement, but the guy who gave me a ticket was a real tool, and not only because he gave me a ticket
I have found that at LEGAL highway speed the speedo is about 5-7 mph off. I always cruise at 72 in a 65 which is really cruising at about 66/67. My portable GPS unit reports speed so I can verify it that way. I have also verified my speed by holding it constant for 1 mile and using a Tachymeter.
