Motorists are being urged to take extra care on the roads this long-weekend, with police targeting speeding, drink driving, seatbelt and helmet offences.

Double demerits will run until midnight on Monday, April 21, with motorists encouraged to be wary of other drivers.

Goulburn LAC Superintendent Zoran Dzevlan said police would focus on maintaining the safety of the community on the roads.

"There are a lot more people on the roads during holiday periods, so we ask drivers to pay even greater attention," Supt Dzevlan said.

"There will be an extremely high police presence over the holiday period.

"We will be targeting speeding, drink driving and unsafe driving. Drive safely and don't drink and drive."

Operation Crossroads, held from April 17 to 21, targets unsafe and illegal behaviours which lead to road trauma over the holiday period.

CEO of ANZPAA, the agency that serves Police Commissioners in Australia and New Zealand, Jon White, said it was disappointing drivers considered getting caught just above the speed limit as "unlucky".

"Road safety research has shown that speeds up to 15km/h over the speed limit contribute to a large proportion of serious injuries," Mr White said.

"So while we think speeding at this range is not as risky, it's more common which increases the likelihood of accidents.

"The simple message is that road users need to respect the speed limits on our roads.

"That is, the speed limit is the absolute maximum you should go. Go above it and you are not only breaking the law, but you are also putting yourself and others at risk," Mr White said.

Police have released a simple checklist for motorists; check the roadworthiness of their car, always wear a seatbelt, never drink and drive, drive to the weather conditions, don't exceed the speed limit, never talk on your mobile phone and take breaks every two hours.
