The number of fatal truck crashes has dropped over the past decade, from a peak of 81 in 2004 to 46 last year, a decrease the New Zealand Transport Agency is celebrating.
The number of serious crashes has also dropped, from 202 in 2004 to 143 last year.
For the year to August, there were 74 serious crashes and 32 fatal crashes.
The drop has also cut the cost of truck crashes by millions of dollars, according to the figures.
The most costly year was 2002, when serious and fatal crashes resulted in a nearly $218 million cost to the country.
