Wide road with yellow lines

Question

In the area were I live there is many up and down hills. The road is wide with yellow lines. Why have no one considered to make the yellow line narrower and make the road duel lane on the uphills? This will eliminate yellow line driving and increase traffic flow since trucks and slower vehicles can move safely out of the way of cars.

Answer

This needs to be taken up and liaised with the local Department of Roads / Public Works
