The correct answer is D; All of the above.
Explanation:
There are numerous roadside hazards all over the world. Sadly, they cannot all be eliminated. However, there are steps to help reduce wrecks and fatalities by moving obstacles and placing barriers to help save lives.
Many places have started burying the lines underground and thus reducing the need the utility poles, but there are some places that this cannot be done. This will depend on the terrain and how rural the area is.
They have also started setting the poles back farther from the roadside. This helps reduce the number of crashes. If the poles are moved farther away, the drivers can correct themselves and keep going instead of hitting a pole and possibly losing their life.
There are now poles that are frangible. These poles will breakaway upon any type of impact. These are only used on the poles that are not carrying live wires.
