Several drivers were lucky to escape serious injury when a truck crashed into a two vehicles before rolling on Dunedin's Southern Motorway yesterday.
Constable Tim Coudret, of Mosgiel, said the truck was carrying gravel on Saddle Hill Rd when its driver appeared to lose control.
During the incident, the truck collided with a northbound and a southbound vehicle.
Emergency services were called about 3.30pm and a St John Ambulance spokesman said two people were taken to Dunedin Hospital with minor injuries.
Const Coudret said there was a lot of damage to the road, barriers and vehicles involved.
''It's extremely lucky that it's not more serious.
''It's an extremely busy time on the motorway, and very lucky that there was minimal other vehicles involved.
''It's just a timely reminder to people to be aware of other traffic, and drive to the conditions.''
The northbound lanes of the motorway were temporarily closed for a time and traffic was detoured through Quarry Rd, in Mosgiel, and along Morris Rd to Fairfield, while a large crane removed the truck.
