Speedometer Calibrations

Speedometer calibrations are often the single most important piece of evidence I present while defending reckless driving cases.  It is extremely important to have your vehicle properly calibrated in order to ensure that it is admissible in court and can be as beneficial as possible to the outcome of your case.  It is essential to select the right shop with the correct equipment.  You will want to take your vehicle to a shop with a dynamometer or “dyno.”  In essence a dynamometer is a devise used to test the accuracy of your vehicles speedometer, among other functions.  The technician will put your vehicle on the dynamometer and measure what your speedometer is reading as compared to the actual wheel speed of your vehicle in order to determine how accurate your speedometer is. 

A favorable calibration will demonstrate to the judge that your speedometer was reading lower than your actual speed.  This will help to show that you were unaware that you may have been traveling at that alleged speed.  Many of the judges that I appear before regularly give my clients credit for the calibration and will reduce a charge down further than he or she may have otherwise been willing to do.

A true calibration will carry the greatest weight in court.  Many of my clients will take their vehicles to a shop without a dynamometer before they have spoken to me.  Frequently these shops will inform my clients that their speed sensor or speedometer cluster is malfunctioning and offer to replace them.  While this can be helpful to a reckless driving case it does not usually carry the same amount of weight as a true calibration.  The reason is that there is no way of determining just how far off their speedometer is and whether it was reading faster or slower than the actual vehicle speed.  I have compiled a list of shops, which have dynamometers so that I can suggest the most appropriate shop for my clients depending on their location.  Finally, you will want to also ensure that the calibration has been notarized in order for the certificate to be admissible in court.  Please feel free to contact me so that we can find the most appropriate calibration shop for you.
