Across the state, police have detected several drivers travelling at speeds significantly above the legal speed limit.

In Mittagong, police stopped a 43-year-old woman travelling at an alleged speed of 183km/h on the Hume Highway.

Police stopped the woman in a 110km/h zone about 8.15am on April 16.

Her licence was suspended immediately and police issued her an infringement for exceeding the speed limit by more than 45km/h.

Two learner drivers were caught driving at speeds of more than 140km/h in separate incidents over the long weekend period.

Assistant Commissioner Michael Corboy of the Traffic & Highway Patrol Command said people needed to slow down on their return home, to ensure the safety of all road users.

“Police continue to be out in force – spending their day away from their own family and friends – in order to keep people safe on the roads,” he said.

“As people return from their long-weekend holidays, the last thing we want is to see is a tragic scene where someone has lost their life or killed another, simply because they are rushing.

With three people killed on NSW roads during the long weekend period, the assistant commissioner said he feared more could die if people did not obey the law, combined with heavy traffic.

“Please slow down, it is more important to get you and your family home safe, than to not get home at all,” Assistant Commissioner Corboy said.

Operation Tortoise – the Easter long-weekend traffic operation – ends at 11.59pm on Monday, April 17. Double demerits will continue until the end of the operation.

From April 13 to 17, more than 6000 speeding infringements were issued across the state and 191,224 breath tests were carried out.

A total of 199 drivers were charged with drink driving, and more than 270 major crashes took place.
