Techniques are described that may be implemented in a mobile electronic device providing navigation functionality to furnish a notification that the indicated speed limit of a roadway being traversed has changed. In an implementation, the display of the mobile electronic device is configured to display navigation information including a roadway graphic representing a roadway being traversed by the mobile electronic device and a speed limit indicator graphic for indicating the speed limit associated with the roadway. When a change in the indicated speed limit is encountered, an attribute of the navigation information is temporarily altered to provide a notification of the change.
