Truck carrying aerosol cans catches fire on Hume Highway

A truck driver has escaped alive after his vehicle packed with aerosol cans erupted in flames on the Hume Highway at Yass.

Police and emergency services arrived at the scene, 1km north of the Yass Valley off-ramp in the road's northbound lane, after the truck caught fire about 6pm on Friday.

Witnesses described the driver detaching the vehicle's cabin from the trailer shortly before the fire took hold.

Yass resident Andrew Hennell said flames shot from the side of the vehicle, and described hearing booming noises from 500 metres away.

"Whatever was in it was going off," he said.

"The fire took hold very quickly."

Yass residents reported a chemical smell in town as the smoke drifted across from the scene.

Motorist Jen Spain reported at least a 500-metre queue of traffic had backed up on the Hume Highway.

The highway's southbound lanes were closed while emergency services dealt with the incident, but the highway was fully reopened on Saturday morning following a "complicated salvage operation".
