one of the many things i dont understand

road signs
why do we need a sign on the side of the road to tells us when the safety barrier is damaged!!!!!!
cause im sure the person who damaged it didn't run into it on purpose and I have no intention of running into it.

also, when there is no safety barrier[sometimes when more in need of one] on the side of the road they don't feel the need to inform us that a tree or the grass has been hit after an accident.


but then again I have no idea why anyone would vote labour either
