Under the new rules, motorists must leave a gap of at least one metre when passing cyclists in speed zones of up to 60km/h. When the speed limit is 60km/h or more, drivers must leave a 1.5 metre gap.

Cyclists are allowed to ride on footpaths, but must use a cycling lane if available.

SA Police said today that they had issued 10 cautions to motorists for failing to keep a safe distance. The cautions were split evenly between 60km/h zones, and those with a higher speed limit.

Police also received 56 complaints via its Traffic Watch system about motorists failing to keep a safe lateral distance from cyclists.

Superintendent Anthony Fioravanti, the officer in charge of the SA Police Traffic Support Branch, said he was “very pleased” with the low number of cautions and complaints.

“It would indicate that most motorists are abiding by the law and safely sharing the road with all road users,” he said.

The fine for driving too close to a cyclist is $287, plus a $60 victims of crime levy. It will also cost the driver two demerit points.
