More than a dozen motorists found out the hard way when they failed to stop for orange and red lights at the London, Pitt and George Sts intersection, in Dunedin, yesterday morning.
Sergeant Chris George said police noted 16 motorists running red lights, or orange lights when it was not safe.
"Most of them accepted that they went through when they shouldn't have, but we still get a few that want to argue the toss."
Sgt George said in some cases motorists who made correct decisions to stop on an orange light when it was unsafe to proceed, were rewarded with an orange lollipop.
"One lady who I had given a lollipop to had been given a ticket recently, so it appears to be having some effect."
The point of the exercise was to prevent accidents involving pedestrians.
