Here is another calculation. A 40 tonne truck traveling at 24.6 kph has the same kinetic energy as a 2 tonne car traveling at 110 kph. But the truck will have more force in a crash at 24.6 kph because it does not crumple as much as the car. The best solutions are more divided roads and more rail freight. Also trucks and 4WDs need to replace their bull bars with softer bumpers. I am not suggesting that trucks travel at 25 kph but it concerns me when they overtake most of the cars on the road.
