With seven truck crashes on roads around the Bay of Plenty so far this month - leaving four dead and three injured - one veteran Rotorua truck driver warns there will be more.
The driver, who asked not to be named, has seen death on the road first-hand.
"It was in the late 90s I was driving a logging truck towards Taupō.
"The other guy was going too fast, he came around the corner, his car spun out and went straight under the front of the truck.
"He died on impact, but I couldn't stop for 30 to 40m and I just dragged his car down the road."
He said he wanted drivers to understand the consequences of their actions on the road.
"My offsider at the time was 17. I saw his father a couple of years ago and he still has nightmares.
"For a long time after that my heart would jump every time a car came around the corner and for a lot of truck drivers they can't get back into it, it's career ending."
A Ministry of Transport study into truck crashes across New Zealand between 2012 and 2016 found 82 per cent of fatal truck crashes took place on the open road and 62 per cent of deaths were the drivers or passengers in the car.
The truck driver predicted New Zealand would see more crashes in the future with heavier trucks on the road and a shortage of heavy truck drivers.
"There is a likelihood of seeing more inexperienced drivers driving the bigger rigs. It's a lot of responsibility."
He said the roads couldn't be blamed for the number of crashes, it was "people not driving to the condition of the roads or the weather".
"It really frustrates me that speed is a factor in a lot of these accidents because that's something car and truck drivers are both responsible for.
"The main causes of truck crashes are impatience, having too many vehicles on the road and people letting their emotions affect their driving."
The study also found 61 per cent of truck crashes involved another vehicle, and there was no fault of the truck driver identified.
Rotorua police area manager for the Commercial Vehicle Safety Team Senior Sergeant Lex Soepnel said driving to the conditions was a crucial part of reducing death and serious injuries on the roads.
"The speed you are travelling at has the biggest impact on the outcome of a crash, whether you are able to walk away from it or not."
On the open road, 90km/h is the maximum speed limit for all heavy vehicles.
"The message to all road users is clear. Don't drive distracted, stay within your own lane, buckle up, watch your speed, and never drive under the influence of drugs or alcohol," Soepnel said.
"It is also vital for everybody to have adequate rest breaks when driving long distance."
