Police believe drugs and alcohol may have been involved in a recent fatal crash at Nimbin and are awaiting toxicology reports.
A 49-year-old nurse died after a four-wheel drive and a van collided at the High Street intersection about two weeks ago.
Detective Chief Inspector Cameron Lindsay has told the ABC that the local community was still reeling after the death of the nurse.
He said no charges had been laid at this stage, but investigations were continuing.
‘I believe we will allege that alcohol and drugs were involved in that matter,’ he said.
‘It is a timely reminder that we don’t want people to drink and drive or take drugs and drive, and we will be enforcing those two aspects over this Christmas period.
Police are also urging cyclists and motorbike riders to take extra care on the region’s roads.
The warning comes after a man in his 60’s died after being knocked off his bicycle on the Pacific Highway north of Ballina yesterday.
That crash came less than a week after a fatal accident involving a motorbike rider on the Bruxner Highway at Alstonville.
Insp Lindsay said police would be conducting random drug testing, random breath testing and there would be speed enforcements on local roads.
‘We don’t want to see any more tragedies in this area.
‘It’s been a really bad year for us. A lot of local people have been dying on our roads.
‘In some cases the emergency responders have known the people involved.
‘It’s really taken a toll on some of those people.’
