Inspector Michael Harrison said driving behaviour across the county has increased in recent years.
He said on a national level, Ireland was now heading for less than 200 road fatalities this year – the lowest since records began in 1954.
Inspector Harrison said people must continue to drive safely across Donegal and to take precautions when they get behind the wheel.
“Donegal drivers are now driving more responsibly than ever before but there are still many risks on our roads.
“We would continue to ask people to slow down and never to take chances.
“We are also asking people not to drive the next morning of they have been drinking the night before,” he said.
