Six drivers were forbidden to drive over the weekend after they were caught exceeding the breath alcohol limit.
Another five people were arrested for exceeding the limit and have been disqualified from driving for 12 months.
Police say they focused on drink driving, speeding and driver behaviour and hoped that decreasing visibility in the bad weather that persisted all weekend would act as a deterrent to motorists.
However despite the warnings, police received were called out to four motor vehicle accidents which resulted in motorcyclists being transported to hospital with minor injuries.
“All were not wearing helmets at the time and had consumed alcohol,” a Cook Islands Police Service spokesman said.
On Sunday afternoon the sea wall road at Nikao was closed due to waves breaking over the wall and police redirected traffic towards the back road.
“Police urge people to take measures to secure household items and property and avoid visiting beach areas and low land areas around the island where waves are likely to reach our roads,” the spokesman said.
If you have any information regarding any of any incidents of interest to the police, call Cook Islands Police Service on 999 (Emergency) or 22499.
