As of 1 January 2008 drivers using Austria's roads are required, under the 29 th amendment to the Motor Vehicles Act (KFG), to have appropriate winter equipment. Between 1 November and 15 April of the following year drivers of private cars and goods vehicles up to 3.5 tonnes maximum gross vehicle weight must be suitably equipped for winter conditions. That means that drivers using the roads in wintry conditions during this period must have winter tyres fitted. Drivers of goods vehicles over 3.5 tonnes maximum gross vehicle weight and buses must comply with a winter tyres requirement. That means that the vehicle must always be fitted with winter tyres during the prescribed period, whether there is snow on the roads or not. This requirement applies to goods vehicles over 3.5 tonnes from 1 November to 15 April and to buses from 1 November to 15 March.
