According to Sergeant David Black from the Mittagong Highway Patrol, 162 motorists were charged with speeding offences over the four-day operation.

"Fourteen people were also issued with tickets for restraint or seatbelt offences," Sergeant Black said.

"Sixty other infringement notices were issued for things such as driving an unregistered or uninsured vehicle, driving without a licence and general traffic offences."

According to Mittagong Highway Patrol only three people were charged with alcohol-related driving offences and one person with a drug-related driving offence.

"It was pleasing to see that there was a very low number of PCA's or alcohol-related offences over the weekend," Sergeant Black said.

"Police from the Southern Highlands and Camden conducted 2599 breath tests over the four days, the majority of which were in the Southern Highlands. It was a good effort all round."

According to Sergeant Black, motorists in the Southern Highlands appeared to have heeded police calls for care on the roads over the ANZAC long-weekend.

"I'm generally happy with the way operations went on the weekend. It is still a matter for concern that 162 motorists were charged with speed-related offences but I was pleasantly surprised by how few alcohol-related offences there were," Sergeant Black said.

"I think that both advertising and the fact it was double demerits points had an effect on the way people approached the road."

Sergeant Black said the majority of speeding offences were low-range offences.
