The driver with the wandering mind caused by stress, emotions or fatigue has a awareness of the road.

a) decreased
b) increased
c) about the same

The answer is A. An emotionally distressed driver is more inclined to be involved in an accident than a driver who is well-rested and clear-headed. It should be made clear that a weary, disturbed driver or a driver who has troublesome thoughts should not be driving. The driver's mind has a decreased ability to avoid those collisions and is probable to be involved in an altercation too.
