Gardaí across County Roscommon will be testing drivers for alcohol and drugs this Bank Holiday weekend.
There will be 41 extra drug testing devices used at checkpoints.
According to the RSA, alcohol is a factor in 38% of all fatal road crashes, while cocaine and cannabis are the most common drugs detected in drivers killed.
The legal limit is for blood alcohol concentration is 50mg, while drivers found to be over the limit but under 80mg receive a three-month driving ban and a €200 fine.
For learners, novices and professional drivers, the limit is reduced to 20mg.
The number of blood and urine samples taken from drivers arrested on suspicion of intoxicated driving between April and June increased by 6.5 per cent even though Covid-19 restrictions brought about a 70 per cent drop in traffic, Garda figures published this week show.
The data also shows there were 1,216 drug driving arrests in the first six months of the year, a 106 per cent increase on the 591 for the same period last year.
The information was released as Gardaí and the Road Safety (RSA) announced a major crackdown on intoxicated driving for the August Bank Holiday weekend.
Assistant Garda Commissioner for Roads Policing, Paula Hilman says drug driving has spiralled. “What we saw in the first six months of 2020 was a total of 1,216 people arrested for drunk driving. There was a increase of 106% compared to the same period last year, that’s 625 more arrests.”
