Illinois Driving Permit Practice Test

What should you do when driving on the expressway?

Use any lane as you wish Keep to the right lane unless passing Always drive above the speed limit Only use the left lane

Correct Answer:

Keep to the right lane unless passing

Explanation:

When driving on the expressway, the best practice is to keep to the right lane unless you are passing another vehicle. This guideline promotes safer and more efficient traffic flow. The right lane is typically designated for slower-moving vehicles and for those who are not actively overtaking others. By allowing faster vehicles to use the left lane for passing, it reduces the chances of congestion and helps prevent accidents that can occur from frequent lane changes and unexpected slowdowns. Using the left lane solely for passing allows drivers to merge and exit more smoothly, as traffic in the right lane is generally flowing at a more consistent pace. This also helps in maintaining a steady speed for vehicles in the right lane, contributing to overall traffic safety.
