The driver of a bin lorry reversed into a telegraph pole, causing it to fall and kill a colleague, Leeds Crown Court has heard.
Ronald Fieldhouse was driving the truck when it mounted the pavement, causing it to fall and strike David Nelson as he worked at the back of the vehicle.
Mr Fieldhouse, 51, of Tadcaster, North Yorkshire, denies causing death by careless driving.
Mr Nelson suffered a severe head trauma in the incident last April.
The court was told Mr Nelson, 56, was a banksman, whose job was to throw rubbish into the back of the truck and help guide the vehicle as it reversed down the road.
'Failed to stop'
The jury was told the cab of the truck was fitted with a monitor which showed the reversing area of the vehicle.
Heather Gilmore, prosecuting, said: "The view from the monitor was so wide, when the wagon was mounting the pavement it was possible for the pole to be seen by the driver.
"The defendant should have been able to see the pole.
"The Crown say the wagon shouldn't have been on the pavement in the first place."
She added: "By reversing on to the pavement, in the way he did, the defendant drove carelessly and he also failed to stop when his banksman disappeared from view."
The incident happened on Beeston Park Terrace in Leeds on 19 April.
The court was told the defendant had undergone training in safety and how to work with a banksman.
The trial continues.
