Traffic diversions are in place on the Hume Highway in the Southern Highlands after an overnight truck fire, NSW Police say.
About 10.40pm today, emergency services were called to the Hume Highway, northbound at Berrima after a B-double, carrying bags of potting mix caught alight.
The 42-year-old male driver was able to stop the truck and attempted to extinguish the fire but was unsuccessful.
He was treated at the scene by NSW Ambulance Paramedics and conveyed to Bowral Hospital with minor injuries to his ears and eyes after an air suspension bag on a trailer exploded in the fire.
Five units from NSW Fire and Rescue and the Rural Fire Service were in attendance and eventually extinguished the blaze.
Road diversions have been implemented and the northbound lanes on the Hume Highway are currently closed with diversions in place at the Old Hume Highway and Medway Road at Berrima while the scene is cleared.
The diversions are expected to be in place for several hours.
