Christmas celebrations turned sour for four drivers who were charged with drink-driving by Timaru police at the weekend.
A Timaru man, 22, was stopped on Wai-iti Rd late on Saturday evening and blew 798 micrograms per litre of breath.
Police also stopped a man on State Highway 1 who blew 752mcg.
A Morven man, 48, was stopped on Craigie Ave after police noticed one of the tyres on his vehicle had a puncture.
He blew 770mcg.
And a Timaru man, 19 was stopped on SH8 and blew 233mcg.
Police would be on the lookout for drink-driving, distracted driving, driver fatigue, and improper seatbelt use over coming days, national road policing manager Superintendent Carey Griffiths said.
Last year, there were 19 people killed and 400 injured on New Zealand roads during the Christmas holiday period, including four deaths and more than 40 injuries from crashes in Canterbury.
"Driving is a skill that requires our full focus, as you literally have your own life and those of passengers and other road users in your hands," Mr Griffiths said.
"Already there have been a number of fatal crashes in the lead-up to the holidays that have left families and loved ones devastated."
Drivers would need to exercise patience and caution, as traffic volumes would increase and more cars would be towing trailers, boats and caravans, Canterbury Senior Sergeant Phil Newton said.
Towing vehicles have a reduced speed limit of 90kmh.
