A significant truck fire has forced the complete closure of the Hume Highway in both directions near the town of Yass, causing major traffic disruptions for holiday travellers and local motorists.
Emergency Response Underway
The incident was first reported by Live Traffic NSW at 9:31 am on Saturday, December 20, 2025. Emergency services, including the NSW Rural Fire Service and Fire and Rescue NSW, responded to the scene. As of 11:45 am, authorities confirmed the fire was being brought under control, but the highway remained closed for safety and clean-up operations.
Major Traffic Diversions and Congestion
Transport for NSW has implemented a major diversion plan for all affected drivers. Motorists are being redirected along Yass Valley Way and the Barton Highway in both directions. However, these alternative routes are already experiencing heavy congestion.
Live Traffic NSW has reported heavy traffic conditions on Yass Valley Way as a direct result of the diversion. Authorities are strongly advising drivers to expect lengthy delays, use the signed detours, and exercise extreme caution while travelling through the area.
