Bus in flames on busy NSW motorway

A bus has burst into flames on the M1 motorway on NSW Central Coast, with firefighters working to extinguish the blaze.

The driver is being treated by emergency services for smoke inhalation and all 16 passengers have safely exited from the bus, which caught alight just before 9.30am on Wednesday on the M1 Pacific Motorway, north of Somersby interchange, a NSW Fire & Rescue spokeswoman said.

Motorists are advised to avoid the area, with the motorway closed southbound approaching Reeves street.
