What is the primary reason for slower vehicles to use the right-hand lane on interstate highways?

To maintain faster traffic flow To make it easier to exit the highway To allow for emergency stops To avoid being overtaken by other vehicles

Correct Answer:

To maintain faster traffic flow

Explanation:

The primary reason for slower vehicles to use the right-hand lane on interstate highways is to maintain faster traffic flow. The right lane is generally designated for vehicles that are traveling at lower speeds, which allows faster-moving traffic to safely pass on the left. This lane usage helps to minimize congestion and enhances overall safety, as it reduces the need for faster vehicles to frequently change lanes. Keeping slower-moving vehicles on the right allows faster traffic to flow more freely, contributing to a more efficient and orderly driving experience on the highway.
