WA Police have warned motorists "don't let your temper get the better of you on the roads" after a frustrated driver became one of the first in the state issued with a $400 fine for failing to keep a safe distance when passing a cyclist.
The new one-metre rule was introduced on Thursday, with drivers found passing too close to a bicycle at risk of being slapped with a $400 fine and four demerit points.
On Sunday morning Wanneroo Police patrolling on Joondalup Drive in Carramar noticed a man in a Toyota Landcruiser pass too close to a cyclist.
Senior Sergeant Simon Hazell said the driver was pulled over and issued a $400 fine and four demerits.
"As I understand it, there may have been some remonstrating (arguing) between the (cyclist and driver)," he said.
"Infringement issued today. Don't let your temper get the better of you on the roads," the tweet caption read.
