Final Answer:
The right lane on a freeway should be kept open for passing slower vehicles, allowing for a smoother flow of traffic and enhancing overall road safety.
Step-by-step explanation:
The right lane on a freeway is typically designated as the "slow lane," and it should be kept open for passing slower-moving vehicles. This practice is essential for maintaining a steady traffic flow and preventing congestion. Drivers are encouraged to use the right lane primarily when traveling at a slower speed than surrounding traffic.
This ensures that faster-moving vehicles can pass safely on the left, minimizing disruptions and promoting a more efficient use of freeway space.
