A driving instructor is in a critical condition after the vehicle he was a passenger in spun out in front of a small truck today.
The crash happened on SH3 between Te Awamutu and Hamilton, just north of Taylor's Hill, about 10.35am.
The driving instructor was trapped in the car and had to be freed by firefighers. He was taken to Waikato Hospital with serious injuries.
District Road Policing Manager, Inspector Freda Grace said the incident was still being investigated by the Serious Crash Unit so it was premature to comment on the cause of the crash.
"But initial indications are that the crash occurred after a northbound car driven by a teenage girl lost control and ended up colliding with a southbound truck."
Mrs Grace said a driver stopped at the scene and spoke to the distraught teenager before speeding off and police would like to speak to this man and any other witnesses who have not yet spoken to the investigators.
Witnesses say it appeared that the crash occurred after a car over-took the Nissan involved in the crash heading northbound. This caused driver of the Nissan to lose control and spin-out in front of a two-axle glass company truck heading south injuring a passenger in the vehicle.
Te Awamutu senior fire officer Lex Soepnel, who attended the scene, said that the drivers of both the Nissan and truck were not hurt in the accident, although the truck driver had to be cut from the truck due to the damage
