Provisional figures released by the Department for Transport confirm that 1,690 motorcyclists were killed or seriously injured in July to September 2011.

This means 18 motorcyclists were killed or seriously injured every day between July to September 2011 - an increase of 2% compared to the same period in 2010 when 1,652 were killed or seriously injured.

While all casualties among car users have reduced by 7%, the figures for motorcyclists have remained stagnant. Around 5,630 motorcyclists were injured between July to September 2011, compared to 5,666 in the same period of the previous year (a 0.64% decrease).

The Institute of Advanced Motoring director of policy and research, Neil Greig, said: “The increase in motorcycling casualties is worrying especially while casualties among car drivers continue to fall. The government needs to ensure that education campaigns targeting motorcycling continue and funding is made available for local initiatives. The police and councils must continue to work together to improve high risk routes, encourage post test training and target bad riding behaviour through innovative enforcement techniques.”
