Of the reviewed crashes that occurred between January 1, 1995 and April 1, 2014, 515 resulted in fatalities and 932 caused serious injury.
The research showed death or serious injury were most likely to occur between 3pm and 6pm Monday to Thursday and on Friday between 6pm and 9pm.
Traffic and Emergency Response assistant commissioner Nick Anticich said there were many factors that contributed to these trends, including peak commuter times, but the message to motorcyclists and other road users was clear.
‘If you are riding a motorcycle in the afternoon, history suggests you are at greater risk of being involved in a serious or fatal crash,’ he said.
‘Whether this be because you are tired from being at work, are in a rush to get home, or maybe you are passing other motorists who are tired or distracted, at the end of the day it is your life at risk, and you need to consider what you can do to stay safer.
‘Motorists travelling in the late afternoons also need to ensure they are alert and not distracted.’
