A Queensland magistrate has called for drivers to be quizzed every few years on recent road rules during their licence renewal process following an inquest into the deaths of two cyclists in Bundaberg.

In 2014 Dr Timothy Kepui was killed in a collision with a car towing a trailer, while a year later Ian Jensen died after being knocked off his bike by a council truck. Both drivers didn't know the safe overtaking distances of bicycle riders.

The deaths two cyclists in Bundaberg prompted a magistrate to call for road rules refresher tests when drivers renewed their licences every few years.

On March 24 magistrate David O'Connell handed down his findings of the inquest into both men's deaths, saying they provided "an opportunity to recommend improvements aimed at reducing the risk to road users".

"It was touched on at the inquest how little drivers knew of the rules relating to safe overtaking distances of bicycle riders," he said.
