Lorries are to be driven into a host of primary schools to highlight a new road safety campaign launched on Tuesday.
Hundreds of children in Oxfordshire are to be shown the dangers of heavy goods vehicles by the drivers themselves.
The county council has joined forces with a haulage company to take the vehicles to six primary schools over the next fortnight.
The drivers will demonstrate the possible dangers posed by turning, reversing, unloading and "blindspots".
Julie Jones, county council road safety officer, said: "We are aiming this programme at 9 to 11-year-olds because we see a huge increase in the numbers of child pedestrians and cyclists injured between the ages of 10 to 14.
"This is often the age they are allowed out unaccompanied but have never had to think about taking responsibility for keeping themselves safe."
