GPS estimates and your car's speedometer

GPS readings may fluctuate or update slowly depending on reception and device conditions. Use this page for general reference only; it is not a certified measuring instrument and does not replace your car's built-in speedometer. Drivers must not use a phone while driving. Check the reading only when safely parked or as a passenger.
