Police, the NZ Transport Agency and the Road Transport Association pulled over commercial trucks on State Highway 1 near Saddle Hill during a half-day operation tackling driver fatigue.
Drivers were given bottles of water and caps, as well as information about sleep apnea and how to avoid fatigue.
Sergeant Andrew Savage, of Dunedin, said they were also checking the basic safety requirements for drivers, such as sobriety, working hours and logbooks.
Out of 110 drivers stopped, only two were pulled aside for logbook infringements and working hour issues.
''There were a couple of issues, but nothing major. It's been pretty good.''
Fatigue was one of the main targets of road policing, he said.
''The key message that we're getting across is that it's the driver's responsibility to come to work rested.''
