Samoa's Land and Transport Authority will soon be using laser speed detectors and radar devices to detect speeding vehicles on its roads.
The LTA said the move was prompted by an increase in the number of road accidents.
Last week, a retired New Zealand police inspector, Ron Philips, was in Samoa training local officials with the devices, which were purchased from New Zealand.
He said he had already seen results.
"I think what LTA have done is the best thing. They've realised there is a problem with speed here and they've introduced now a measure to deal with it. Before they had no measure. They didn't have equipment. I have seen drivers spot us straight away and know what's going on and reduce. And that's the whole business, that's all we want to reduce speeds, injuries and fatals."
