HIGHWAY patrol and general duties police have been highly visible on Coffs Coast roads as part of a state-wide safety operation.
In the first 24 hours of Operation Tortoise, police issued 1559 traffic infringement notices, including 882 for speeding.
However, NSW Police Traffic and Highway Patrol Command Assistant Commissioner, John Hartley, said police were alarmed at the excessive number of high range drink driving offences detected.
"Motorists returning high range drink driving readings is of great concern to police," Assistant Commissioner Hartley said.
"At least an entire generation has grown up with random breath testing and it is astounding people still choose to take the extreme risk and get behind the wheel of a car after drinking.
"Drink driving is both illegal and deadly with drivers under the influence losing their ability to make decisions and operate a vehicle safely."
The Pacific Highway was again the scene of one of the worst examples of dangerous driving.
A man will face court next month after allegedly being detected travelling at a speed of 200kph in a 100kph zone.
The man, believed to be a Chinese national, was detected while officers were conducting speed enforcement on the Pacific Highway near the Macleay Valley Bridge.
