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:

The fast lane on a freeway is intended for passing. If a driver is driving slowly and blocking traffic, the safest and most appropriate action is to change lanes to the right when it is safe. This allows faster - moving traffic to proceed. The other options are incorrect: waiting for five or more vehicles is not a standard rule; not changing lanes when driving the speed limit is wrong because the speed limit may be lower than the typical speed of traffic in the fast lane (which is for passing); and turning on emergency lights is for actual emergencies, not for indicating that others should pass.

Answer:

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