Police are urging people to stick to the basics of road safety after a three car collision left two women in a serious condition.
The cars collided just before 10pm last night on State Highway 23 near Whatawhata.
Waikato Road Policing Manager, Inspector Marcus Lynam, says it appears a car crossed the centre line and collided head-on with another car, which was rear-ended by the car behind.
The collision was between two cars travelling west towards Ragland and a car heading east towards Hamilton, Lynam said initial indications showed.
"It appears the eastbound Nissan Bluebird crossed the centreline and collided head on with a Suzuki Swift car, the driver of a Hyundai Sonata who had been travelling to Raglan with the driver of the Suzuki managed to break and avoid all but a minor impact with the rear of the Swift," he said.
Two women were taken to hospital with serious injuries. One is in a critical condition.
Lynam is urging drivers to be mindful of the fatal five: speed, alcohol, keeping left, seatbelts and reckless or dangerous driving.
"If everyone takes care to avoid involvement with each of these factors we will all be driving to survive and ensuring safer journeys for all road users," he says.
Police are awaiting the results of toxicology tests to determine what part, if any, alcohol played in the crash.
