Check points will be in place across the county over the course of the bank holiday weekend and particularly on St Patrick's night, a senior Donegal garda has confirmed.
Inspector Michael Harrison urged people to exercise caution and adhere to the rules of the road whilst driving on the roads this bank holiday weekend.
Five people have lost their lives on the county's roads this year.
He said: "I am asking all road users in Donegal this weekend to drive at a sensible speed for the particular road conditions and wear your seat belt, don't drink and drive and don't use your mobile phone."
Detections for the number of people who have been found to be driving without their seat belts in the county have risen significantly.
There has also been a noted increase in the number of people detected using their phones whilst driving, despite repeated garda warnings.
The March bank holiday is traditionally a high risk period for drink and drug related crashes.
He said: "I have scheduled a number of operations throughout the county particularly on St Patrick's night itself. We will be doing a number of ordinary drink driving checkpoints and also a number of mandatory intoxicant check points, where you are likely to be stopped and tested for alcohol or drugs. Again, just to remind people that we can test for drugs, we have the machinery to test for drugs and people are being detected drug driving all the time. It is just not worth it you are putting your own life at risk and the lives of others at risk."
