"The male driver of the car suffered serious to critical injuries while the man travelling as a front seat passenger suffered serious injuries. Two men travelling as rear seat passengers were shaken but unhurt in the crash and the two injured males were taken to Waikato Hospital by ambulance."
Mrs Grace said with icy roads, busier traffic flows with the return of children to school following the holidays and the general risks associated with winter driving, the last thing motorists should be considering is drinking and driving and driving at speed.
Then, just before 8am, a police officer noticed a driver fail to give way on Boundary Rd.
"On stopping the car and speaking to the 53-year-old male driver our officer noticed a strong smell of cannabis and located a small quantity of the drug in the car," Mrs Grace said.
"When the driver failed a roadside impairment test he was taken for a blood test and pending the results of this, faces potential drugged driving charges."
She said it was completely unacceptable behaviour by drivers, and today's incidents showed a selfish disregard for the safety of other road users.
