NSW Police is preparing for Operation Tortoise, the state's Easter long-weekend road safety operation, which starts at 12.01am on Thursday, April 18 2019 and continues until 11.59am on Monday, April 22, 2019.

Police will be targeting all speeding, mobile phone, seatbelt and motorcycle helmet offences.

"With the Easter long weekend and Anzac Day holiday close together this year, we're expecting more cars on the road which will cause delays along major arterial and feeder roads, so allow additional travel time to your trip," Far North Region traffic tactician Inspector Peter Mcmenamin said.

"Fatigue-related crashes are one of the biggest killers on NSW roads and it's important drivers get a good night's sleep and plan ahead before they get on the road.

"Driving while tired increases your risk of being involved in a crash that could have fatal consequences for you, your family or other road users, so taking regular breaks on long trips could be lifesaving."

Minister for police and emergency services David Elliott said police would be out in force ensuring motorists obey speed limits.

"This is an exciting time of year when families get together and enjoy themselves. We want everyone to have a great time during the break," he said.

"Often families hit the road for a holiday with the kids, so we want every motorist to take great care behind the wheel this Easter and Anzac Day and ensure they arrive safety at their destination."

Double demerits will return on April 24, 2019, until 11.59pm April 28, 2019 as part of Operation Go Slow during Anzac Day.
