8) studies have shown that wider highway lanes lead to fewer accidents. which factor most likely prevents states from widening roads to double lane sizes? a) cost eliminate b) technology c) speed limits d) driver confusion

A) Cost

Explanation:

One of the main reasons why these changes would be hard to implement everywhere would be cost. If states decided to widen the roads to double lane sizes, many roads would have to be rebuilt, or at least repainted. Signs and lightning would also have to be changed, and some extra roads might be necessary in order to accommodate traffic. All of these measures would represent a significant cost for states.
