Only nine drivers out of more than 850 failed the test when police conducted a two-day operation in Albury focusing on drink and drug driving.
Operation Fume, held last Friday and Saturday, included more than 760 random breath tests and 114 random drug tests.
Acting Sergeant Matt Stephenson, of Albury Highway Patrol, said there were two positive tests for alcohol and eight for drugs.
"It's a pleasing result," he said.
"We did a lot of tests over those two nights and the fact that we only got a very low number of positives is a good reflection on the attitudes and behaviours of people locally."

Acting Sergeant Stephenson said a similar campaign would take place later this year.
"These operations roll over regularly," he said.
"It's part of our ongoing commitment to providing safer roads to local residents by removing drunk and drug-affected drivers, in addition to also tackling hoon and anti-social behaviour on our roads."
Police will continue to focus on the four D's: distracted, drug, drink and dangerous driving. Anyone who witnesses dangerous driving on our roads can contact police or Crime Stoppers on 1800 333 000.
