THE number of people killed in crashes involving heavy vehicles has dropped by 20% over the past five years.
It has been revealed 225 people died in 200 crashes involving heavy vehicles on Australian roads in the 2011-12 financial year.
The figures were released by the Bureau of Infrastructure, Transport and Regional Economics on Friday.
Parliamentary Secretary for Infrastructure and Transport Catherine King said while the number of fatal crashes and fatalities had continued to fall, any loss of life was unacceptable.
"This latest report shows that over the last five years the number of crashes involving articulated trucks and rigid trucks has decreased by 13%," Ms King said.
"Also the number of fatal articulated truck crashes is down by 18%, as well as fewer fatalities from heavy bus crashes with a 4.2% decrease from the year before."
She said the establishment of the National Heavy Vehicle Regulator would help in reducing the number of death even further.
