Final Answer:
If you are driving slower on a 2-lane road and 5 or more cars are following you, you must pull to the side and let them pass. Option C is the answer.
Step-by-step explanation:
This traffic rule emphasizes the importance of maintaining a smooth flow of traffic, especially on two-lane roads. If a driver is traveling at a slower pace and accumulating a queue of five or more vehicles behind them, it is a signal to pull over safely and allow the trailing vehicles to pass. This practice enhances road safety, reduces frustration among drivers, and helps prevent traffic congestion.
The specified threshold of five or more cars, as indicated in option C, is a guideline that recognizes the need for considerate and efficient driving on two-lane roads.
Option C is the answer.
