If you’re thinking about getting your speedometer calibrated, you need to make sure it will be admissible in court. Instead of just telling clients what to do, I went straight to the source. I recorded the entire calibration process, so you can see what the mechanic should be doing.
For calibrations in the greater Fredericksburg area, I recommend the shop we went to:
Falls Run Car Care
1314 Princess Anne St
Fredericksburg, VA 22401
(540) 899-6800
They charge $65 for the calibration, and they only accept cash.
When the calibration is done, the mechanic should give you a notarized calibration certificate that shows the actual speed versus the speedometer reading. Here is the calibration report for the calibration you saw above.
