Aussie quad bikes to get mandatory roll bars

All quad bikes sold in Australia will have mandatory roll bars within two years under new safety rules aimed at saving farmers' lives.

Assistant Treasurer Michael Sukkar announced the change on Thursday after sustained pressure from the agriculture lobby.

The new regulations would also require bikes to have roll warnings within a year.

"This safety standard aims to address the high risk of rollovers, which is especially important for many of our farmers and their families who use these vehicles daily," he said in a statement.
