Hypotheses and outcome measures
DrivePoints, crash, DrivePoints’, crashes
The The 
Reducing the incidence of self-reported crashes by young drivers.Improving drivers’ safety scores (‘DrivePoints’ scores) from baseline.Reducing crash risk behaviours identified by speeding, harsh braking, hard acceleration, and drowsy driving from baseline.The 
Self-reported involvement in a crash that took place during the 24-week intervention and post-intervention periods that resulted in damage to their own or someone else’s vehicle.DrivePoints score at baseline and at weekly intervals through to week 28.Driving behaviours, namely:
Speeding (defined as 10 km/h over the speed limit).Harsh braking (sudden braking in which items in the vehicle would move around, defined in telematics technology as a -0.5 g force).Hard acceleration (rapid acceleration exceeding a 0.25 g force).
