Indiana Bureau of Motor Vehicles Permit Practice Test

Which lane should slow-moving vehicles use on highways?

1. Left lane

2. Right lane

3. Middle lane

4. Any available lane

The correct answer is: Right lane

Slow-moving vehicles are required to use the right lane on highways for several important reasons. The right lane is designated for vehicles that are traveling at lower speeds, which helps maintain smooth traffic flow and enhances safety on the road. When slower vehicles occupy the right lane, it allows faster-moving vehicles to pass safely in the left lane without having to maneuver around slower traffic. Using the right lane also helps reduce congestion and risks of accidents. If slow-moving vehicles were allowed in the left lane, they would hinder the progress of faster vehicles, leading to frustration among drivers and increasing the chances of dangerous lane changes and collisions. Furthermore, it is generally a legal requirement in many jurisdictions, including Indiana, for slower vehicles to keep right, ensuring they do not impede traffic. This is beneficial not just for the drivers of faster cars, but also for the slow-moving vehicles themselves, as it minimizes their potential for dangerous interactions with faster traffic.
