Before June 2023, New South Wales experienced significant numbers of over-height vehicle incidents and detections, disrupting the road network, impacting the economy, and posing safety risks to tunnel and bridge infrastructure and road users. To tackle over-height vehicle incidents in New South Wales, a taskforce was formed mid-2023, including Transport for NSW, the National Heavy Vehicle Regulator, and NSW Police. A 32% incident reduction and 67% closure minute reduction were achieved in six months through collaborative strategies and improvements, with further enhancements planned.
