Volunteer firefighter John Klaphake has been found guilty of careless driving.
Last year Klaphake ran a red light and crashed into an SUV on the way to a house fire in Newtown.
Judge David Wilson handed down the verdict at Wellington District Court this afternoon.
He says Klaphake's actions were careless and made a substantial contribution to the crash and the injuries sustained by the driver of the SUV.
Immediately after the verdict was handed down Klaphake's lawyer made an application for the judge to consider special circumstances.
