'Ludicrous': 7687 NSW Easter speeders

More than 7600 NSW drivers were nabbed speeding during the Easter long-weekend with police describing the figure as "ludicrous".

Over five days, 7687 drivers were detected speeding, despite double-demerit enforcement and more than 1300 traffic cops taking part in Operation Tortoise, police said on Tuesday.

Four people died on NSW roads this Easter.

"If that is not enough to deter drivers from speeding, I don't know what is," Assistant Commissioner Michael Corboy, of the Traffic & Highway Patrol Command, said.

"The fact that over 7500 drivers were still detected speeding over a single long-weekend is ludicrous," he said.

Speeding is a contributing factor in about 40 per cent of fatal crashes, Mr Corboy said.
