Which statement best describes the far-right lane rule?

• A. Tow a vehicle or trailer
• B. Drive a bus
• C. Drive a truck with three or more axles
• D. All of the above

Answer: (D)

In traffic, the far-right lane is kept open for slower-moving vehicles and those that need extra space to maneuver. Vehicles like those towing a vehicle or trailer, buses, and trucks with three or more axles typically accelerate and merge more slowly, so they are expected to use the rightmost lane. This helps prevent faster vehicles from being blocked and reduces weaving between lanes. You stay in the far-right lane when you’re not actively passing, and you move left only to pass or to prepare for a turn or exit. Because all these types of vehicles fit the idea of slow or space-intensive movement, the statement that includes them all best describes the far-right lane rule.
