1. A vehicle speed monitoring device, comprising:

  • an interface for receiving information from one or more input devices;

    a timer; and

    a processor operable to;

    determine a speed and location of a vehicle using the received information,compare speed limit mapping data to the determined location of the vehicle to determine a posted speed limit corresponding to the determined location of the vehicle,determine a first threshold speed and a second threshold speed, the first and second threshold speeds corresponding to the determined location of the vehicle,perform an action if the speed of the vehicle exceeds one or more of the first threshold speed or the second threshold speed,wherein the vehicle speed monitoring device is configured to generate a warning to a driver when the speed of the vehicle exceeds the determined first threshold speed and wherein the vehicle speed monitoring device is even further configured to generate a notification signal to a remote computing system when it is determined that the driver has failed to reduce the speed of the vehicle within an amount of time after the warning is generated or when it is determined that the speed of the vehicle exceeds the second threshold speed, wherein the notification includes at least a location of a worst excess speed over the first or second threshold speed;

    locally store a plurality of different speeding violation records corresponding to different speeding events, each of the speeding violation records identifying a corresponding location and a corresponding speed of the vehicle for each speeding event;

    periodically send a group speeding record notification for the plurality of different speeding violations to the remote computing system according to a periodic reporting interval; and

    send a notification for a particular record of the different speeding violation records to the remote computing system independent of the group speeding record notification upon determining that a speed of the vehicle associated with the particular record exceeds a threshold speed by a predetermined amount.
