Acting Sergeant Chris Lemon said he was a spotter at traffic lights in Crawford St for an hour yesterday, advising officers further along the one-way system of drivers' bad behaviour.
The waiting staff then stopped and ticketed the offending motorists near Jetty St, he said.
In yesterday's operation, 19 motorists were ticketed, he said.
About half the tickets were for motorists ''running the lights'' and the rest for using a cellphone while driving, not wearing a seat belt and not having a current warrant of fitness, he said.
Police staff ticketed another 19 motorists in the same place in about an hour and a-half on Monday. The infringements on the first operation were a similar mix to yesterday, Sgt Lemon said.
He was surprised by the number of motorists using cellphones while driving, ''especially on a busy road like that''.
