GRSP is pleased to provide our penalties guidance document. The levels of trauma that occur globally every day from preventable road crashes remains unacceptably high. This guide provides direction on how a suite of penalties can be used to deter road users from behaviours that either cause or worsen road trauma. Enforcement programmes supported by targeted public awareness programmes focusing on alcohol-impaired driving, speeding and use of seat belts, child restraints and motorcycle helmets are highly effective at reducing serious crash casualties. There is an opportunity for law makers to develop programmes even more effective by applying a combination of penalties that are known to work. This document will serve as reference for governments wanting to improve their penalty systems to maximise their impact on improving road safety.
