Gardaí report that more than 1,500 drivers are caught speeding during the first two days of an August Bank Holiday roads policing operation. Multiple outlets say a driver is detected travelling at 172 km/h. Overall, the operation identifies large numbers of speeding offences, with figures reported as exceeding 1,500 and approaching 1,600 by the early stage of the operation. In addition to speeding, Gardaí state they detect other driving offences. One source reports that 200 drivers are identified for using a mobile phone or for not wearing a seatbelt, in line with road-safety enforcement activities. Gardaí also arrest drivers: 39 people are arrested on suspicion of drink or drug driving during the first two days. The reports present the initiative as a targeted enforcement period, combining speed detection with checks for other contraventions and arrests where suspected impaired driving is identified. Details of locations or how many of the speeding detections involve fixed or mobile enforcement are not provided in the supplied summaries.
