"There hasn't been a spike in people drink-driving, that we've caught anyway. That's also very pleasing.
"There have been a few instances where people have probably been caught speeding around town just because the roads are quieter but, having said that, it hasn't resulted in any crashes or carnage.
"That's the difficult thing to prove, though, what you actually prevent. We're out there stopping people speeding and making sure they're wearing a seatbelt, but you never know what you've prevented."
Despite the traditionally quieter roads in the area around New Year's Eve, Wright said motorists should remain vigilant.
"So far, things are good. Traffic is light and people are, on the whole, behaving well.
"Even if the roads are lighter and quieter, keep the speed down, and don't drink and drive. If you're going to drink, get someone else to drive."
There would be "a lot of police" on duty on New Year's Eve, breath-testing and monitoring traffic, Wright said.
"Historically, people tend to leave Whanganui and go elsewhere for New Year, and I don't there's anything huge planned in town.
"We've been good and, touch wood, let's hope it continues."
