454 drivers were detected speeding between 7am yesterday morning and 7am today during 'Operation Slow Down.'

Gardai launched the 24 hour initiative in an effort to reduce the number of speed-related collisions and officers say reports from around the country show the message was heeded, and there was a visible reduction in speed.

During the operation, GoSafe checked 104,966 vehicles and detected 454 vehicles speeding.

However, some of the highest recorded incidents of non-compliance show one motorist driving at 124kmh -in a 100 kmhzone - on the N18 Cratloekeel in Clare with another motorist travelling at the same speed on the N5 at Ballymacrah in Castlebar county Mayo.

Gardai are asking motorists to continue to drive safely and to slow down.
