The eighth edition of the NTARC Major Accident Investigation Report is a document, like the industry on which it reports, containing both change and continuity.

In the transport industry, in 2017 (the data examined in this report) we saw a stagnation in the overall safety performance of the heavy vehicle fleet, with around 1 heavy vehicle involved fatal crash per billion tonne kilometres of freight.

This measure of safety performance consistently improved from 1.85 in 2004 to just over 1 in 2015, however remained essentially static at that level through 2016 and 2017. Between 2015 and 2017, the number of heavy motor vehicles insured by NTI increased by 10%.
