Question

when you are driving slowly in the freeway fast lane, blocking traffic which wishes to pass, you should:
change lanes to the right when it is safe to do so
only change lanes when there are five or more vehicles behind you
not change lanes when you are driving the speed limit
turn your emergency lights on to signal other vehicles that they need to use another lane

Explanation:

To solve this, we analyze each option based on traffic rules. In freeway driving, the fast lane is for faster - moving traffic. If you're driving slowly in it and blocking others, the correct action is to move to the right lane when it's safe. The option “Only change lanes when there are five or more vehicles behind you” is incorrect as there's no such rule. “Not change lanes when you are driving the speed limit” is wrong because if you're in the fast lane and slower traffic is behind, you should move right regardless of your speed relative to the limit. “Turn your emergency lights on to signal other vehicles that they need to use another lane” is incorrect as emergency lights are for emergencies, not for this situation.

Answer:

A. Change lanes to the right when it is safe to do so
