One second Jacob Ohs was driving along Johns Rd (State Highway 1) in Christchurch, the next the car he was in was skidding upside down after colliding with another vehicle.
Ohs, 17, and four friends in the car were lucky to walk away from the crash with no, or only superficial, injuries after their car slid for what they thought was more than 100m.
Ohs said they were in the right lane heading north towards the Sawyers Arms Rd roundabout when a vehicle in the left lane changed lanes. His vehicle clipped the back of it and he lost control.
The crash comes as Waka Kotahi NZ Transport Agency warns drivers about road safety as summer approaches.
