Police are investigating after a vehicle caught fire on the M1 at Somersby overnight leaving two men in hospital.
Shortly after 10pm, a Toyota Hilux was travelling in the northbound lanes with three occupants.
Police have been told that something close to the driver seat suddenly exploded or caught fire.
This caused serious burns to the 27-year-old male driver’s arms and legs and he pulled on the handbrake which caused the Toyota to strike the nearside guard rail.
The 25-year-old rear seat passenger saw the flames and jumped from the vehicle while it was still moving.
The front seat passenger, a 38-year-old man, escaped from the vehicle after it stopped and pulled the driver from the car.
The two passengers then dragged the driver away from the vehicle.
Emergency services were quickly on the scene and fire fighters extinguished the blaze however the interior of the vehicle was completely destroyed.
Police from Brisbane Water Local Area Command attended and commenced investigations into the incident.
The driver sustained major burns to 18 per cent of his body and was treated at the scene before being conveyed to the Royal North Shore Hospital by Ambulance paramedics. The rear seat passenger was conveyed to Gosford Hospital with injuries sustained after he jumped from the moving vehicle and minor burns.
The vehicle was removed for further mechanical examination.
Anyone with information that may assist investigators is urged to contact Crime Stoppers.
