Drunk cyclists and pedestrians are potentially causing scores of car accidents every year in Victoria, prompting calls for them to be breath-tested and subject to the same road rules as drivers.

A leading trauma doctor has called for new laws after a study found hundreds of drunk cyclists and pedestrians were seriously injured in collisions with cars and motorbikes in Victoria between 2009 and 2014.

Some of these people had blood alcohol readings up to 0.4 - eight times the legal limit for drivers. Dozens were between 0.1 and 0.3.

The Alfred hospital emergency and trauma specialist Biswadev Mitra​ and his colleagues looked at 1323 Alfred patients who were seriously injured in road accidents when they were not driving.
