RESEARCH - The Nature of Errors Made by Drivers

Austroads LogoHuman error is responsible for between 75% and 90% of crashes, but this report from Australia suggests that the system that a driver makes the error within needs to be more carefully examined. The system either contributes to the error or shapes the driver's behaviour that produces the error.

The most common driver difficulties are related to speeding, changing lanes without a signal immediately after turning at an intersection, not signalling at all or too early and travelling too fast for a turn.
