Driving distractions may result in slowed perception of an important traffic event. Which option describes this effect?

Answer: B — Slowed perception of an important traffic event

When drivers are distracted, their brain’s processing of road information slows, so important traffic events are perceived more slowly. That delayed recognition can lead to slower or late reactions, increasing crash risk. So the description of slowed perception best matches what happens with distractions. The other ideas—faster perception, increased attention to hazards, or no impact—don’t reflect how distraction typically affects awareness and response on the road.
