It came up at the AMC conference last weekend that Australian Road Rule 299 explicitly forbids use of a GPS system on a motorcycle. So far it appears SA is the only jurisdiction enforcing this but I suspect if others catch a whiff of the revenue raising abilities here then they'll do it as well. this applies not only to after market GPS systems but to those that come inbuilt (like the new Goldwing). 299—Television receivers and visual display units in motor vehicles (1) A driver must not drive a motor vehicle that has a television receiver or visual display unit in or on the vehicle operating while the vehicle is moving, or is stationary but not parked, if any part of the image on the screen: (a) is visible to the driver from the normal driving position; or (b) is likely to distract another driver. Offence provision. Note— "Motor vehicle" and "park" are defined in the dictionary, and "vehicle" is defined in rule 15. (2) This rule does not apply to the driver if: (a) the driver is driving a bus and the visual display unit is, or displays, a destination sign or other bus sign; or (b) the vehicle is not a motor bike and the visual display unit is, or is part of, a driver's aid and either— (i) is an integrated part of the vehicle design; or (ii) is secured in a mounting affixed to the vehicle while being used; or (ba) the visual display unit is a mobile data terminal fitted to a police vehicle or an emergency vehicle; or (c) the driver or vehicle is exempt from this rule under another law of this jurisdiction.
