Intelligent Speed Assistance (ISA) is an in-car technology that can substantially reduce road crashes by helping motorists to stay within speed limits. ISA is becoming more widely available in UK vehicles.  Behavioural interventions are required to encourage drivers to use ISA in order to maximise its potential public health benefits. 

This presentation reports the development and evaluation of a brief intervention to encourage ISA use structured by the Theory of Planned Behaviour. The intervention strengthened intention to use ISA with a medium effect size that was maintained after one week and remained significant after one month. 

The intervention is suitable for presentation to motorists when they purchase their first ISA enabled vehicle and could also be applied in a range of other settings. All intervention materials are freely available.
