"The driver is usually a close family member and the devastating impact of these events upon families cannot be overstated," Ms Weaver said.
Raising awareness was the key to preventing more people having to live with that tragic consequence.
"Make sure you know where the children are at all times and don't assume. If you can't see them, you need to get out and ensure they are being supervised by another adult."
She said children could move so fast that it was essential a driver knew for certain when entering or leaving a driveway that a youngster was not running around.
Signs warning that children could be playing in the driveway were a good idea.
"Five deaths (a year) is far too many and people need to realise that they cannot see everything around their vehicle with their rear view and side mirrors," Ms Weaver said.
Up to 10 metres at the back of a vehicle and three metres at the side and in front can be blind zones for drivers.
"People think they are driving in a bubble and that they can see everything inside that bubble, but that's not the case.
"We want to prevent more children dying in this way and people having to live with those terrible consequences," Ms Weaver said.
