In 2013, 39 motorcyclists died and a further 1,188 were injured in road crashes. This was 15 percent of all deaths and 10 percent of all reported injuries on our roads.
Motorcyclists killed and injured (1980–2013)
The number of motorcyclist casualties dropped markedly during the 1990s to a minimum between 2000 and 2004. Numbers increased between 2004 to 2008, but have dropped again since then.
Motorcyclists now make up 10 percent of all road users injured, compared to 21 percent in the early and mid-1980s.

Table 2: Motorcyclist deaths and injuries, selected age groups
Note: columns do not necessarily add up to the totals, due to unknown ages for some riders.
As shown in the graph below, the drop in motorcyclist deaths and injuries during the 1990s was particularly marked among the young, while the recent increase has occurred in the over 40s age group.
Motorcyclist deaths and injuries by age group
The proportion of crashes that result in death is higher for large motorcycles than for small motorcycles — riders of large (500cc or bigger) motorcycles make up 39 percent of all casualties but 66 percent of deaths. This is, at least partly, a result of riding patterns. Small motorcycles and scooters tend to be used for ‘around-town’ riding, where speeds are low, whereas large bikes spend a much greater proportion of time on the open road and travelling at higher speeds3. For bikes 500cc or bigger, over half (55 percent) of all reported injuries are on the open road. This compares to only 17 percent for small bikes with an engine size under 250cc, and about a third (36 percent) for bikes with engine sizes of 250–499cc.
Who was at fault?
Motorcyclist fault in crashes (2009–2013)
Percentage of motorcycle crashes in which a motorcyclist had the primary responsibility for the crash (2009–2013)
Percentage of crashes where motorcyclist has the primary responsibility for the crash
A motorcyclist has the primary responsibility for 55 percent of fatal and injury crashes involving motorcycles. For fatal and serious injury crashes, the motorcyclist is more likely to have the primary responsibility for the crash. The motorcycle rider has the primary responsibility for 67 percent of fatal motorcycle crashes, but the comparable figure for minor injury crashes is 51 percent.
In about two-thirds (66 percent) of the crashes that involve a collision with another vehicle, it is the other vehicle that has the primary responsibility for the crash.
Motorcyclist alcohol/drugs and speed in fatal crashes (2009–2013)
Of motorcyclists involved in fatal crashes, 27 percent are affected by alcohol/drugs; 30 percent are travelling too fast for the conditions; and 43 percent are travelling too fast for the conditions and/or are affected by alcohol/drugs.
Types of crash
Type of crash by speed limit area and crash severity (2009–2013)
The rider losing control of the vehicle is a major feature in motorcycle crashes. As well as those shown in the ‘Lost control/run off road’ category in the table, 31 percent of head-on crashes result from a rider losing control of the motorcycle.

When do crashes happen?
Fatal and injury motorcycle crashes (2009–2013)
Note: Crashes in 4 hour blocks beginning 00:00 Monday.
The peak times for motorcycle crashes are between 12 noon and 4pm on Saturdays and Sundays, and between 4pm and 8pm on weekdays.
Where do crashes happen?
Motorcycle crashes on urban roads (speed limit of 70km/h or less) and open roads (2009–2013)
Nearly two-thirds (65 percent) of all motorcycle injury crashes occur on urban (speed limit of 70km/h or less) roads, but nearly three quarters (74 percent) of fatal crashes are on the open road.
Most casualties are male
81 percent of all injured motorcyclists, and 95 percent of motorcyclist deaths, are males.
Licence status of motorcyclists in crashes
Licence status of riders in crashes (2009–2013)
Note: The crash data does not distinguish whether or not a moped rider held a motorcycle licence. 12
Fatal injuries: injuries that result in death within 30 days of the crash.
Serious injuries: fractures, concussions, internal injuries, crushings, severe cuts and lacerations, severe general shock necessitating medical treatment and any other injury involving removal to and detention in hospital.
Minor injuries: injuries of a minor nature such as sprains and bruises.
Social cost: a measure of the total cost of road crashes to the nation. It includes: loss of life and life quality; loss of productivity; and medical, legal, court, and property damage costs.
Casualty: person who sustained fatal, serious or minor injuries.
