Some 78 motorists per day have tailgated another vehicle in a bid to avoid the €3.10 charge on Dublin's M50 in 2013.

According to the latest figures released by Sanef Ireland, operator of eFlow,  this figure represents a 67% reduction in tailgating offenses since a high in 2010 when rear-facing cameras at the toll were introduced to tackle the problem.

The act of tailgating involves motorists driving within inches of heavy goods vehicles in an attempt to hide their licence plate number from overhead toll cameras.

Director of Communications and Customer Relations at eFlow Simon McBeth said: 'Tailgating is a reckless act that puts lives at risk for the sake of avoiding a €3.10 charge.

“While we introduced measures to combat the problem, there remains a number of motorists who continue to offend and we're asking them to stop,” he said.

The latest figures were released by Sanef Ireland today as Minister for Transport Leo Varadkar officially opened the new eFlow offices in Blanchardstown.
