In 2016, there were 18 deaths on Tongan roads but in the year ending November there have only been five deaths.
Acting Chief Superintendent Tevita Vailea said while it was encouraging that 13 less people died than last year, it was of little comfort to the families and friends of victims, and to the people who were injured or traumatised by crashes.
Police were called to 262 crashes around the country during the January to November period.
