There have been no serious accidents on Southern Highlands roads since the annual Christmas blitz commenced on December 19, although the area has not remained free from tragedy with a 41-year-old Moss Vale man being killed in a collision between his motorcycle and a panel van at Londonderry.

More than 450 speeding tickets have been issued by highway officers, with a further 19 seatbelt infringements and 31 miscellaneous offences being recorded.

The fact that only nine of almost 3360 random breath tests have proved positive has represented an improvement on previous years, though Senior Sergeant Pieter Strik has warned New Year's Eve revellers that police are not yet content and are still on high alert.

"Touch wood, we've been lucky, but there are still people out there who are not accepting responsibility for their own stupidity and that is worrying," said Sergeant Strik.

"We've been out there hammering offenders but it's ridiculous the way some people have been driving.

"None of us are on leave, we've got the maximum number of cars out on the road and we're urging people that may be thinking of taking the risk of drinking and driving on New Year's to use their commonsense.

"We want everyone to think of other people's families and think what a bad start to 2004 it will be for anyone who loses a loved one because somebody gets tanked up and then tries to drive home.

"There have been a lot of deaths on local roads this year and we're hopeful that we won't be starting off the new year with another."

A 33-year-old woman more than four times the legal limit has registered the worst blood alcohol reading during Operation Safe Arrival so far.

The woman, who had her licence suspended and her car keys confiscated after recording a reading of 0.210, drove from Robertson to Braemar on Boxing Day before she was stopped by police.

The highest speeds clocked - both on the Hume Highway in wet conditions - have been 173km/h by a Sydney man and 164km/h by an American man.

Two truck drivers have been caught travelling more than 20km/h above their 100km/h speed limit on the highway also.

Double demerit points for speeding and seatbelt offences, which came into force on Christmas Eve, will continue to be imposed until Sunday.
