Introduction Low light levels reduce vision and are an impediment to safe driving. The national standard for vehicle window tinting was first adopted in the Northern Territory (NT) in June 1984 and provided for not less than 70% luminous transmittance (LT) on the driver and front passenger side windows with the rear windows required to have not less than 35% LT. As part of the National Road Transport reform process, in the form of the Australian Vehicle (Standards) Rules, provision has been made to allow States and Territories to relax the window tinting requirement for in-service motor vehicles. The NT’s requirements are outlined in this Bulletin.
