Idaho Written Driver's License Practice Test

When driving on a two-way street with two lanes in your direction, when should you leave the right lane?

1. When overtaking and passing another vehicle

2. When you are planning to make a U-turn

3. When there is road construction on the right lane

4. When approaching a traffic signal

The correct answer is: When overtaking and passing another vehicle

Leaving the right lane on a two-way street with two lanes in your direction is appropriate when you are overtaking and passing another vehicle. In this scenario, the right lane is generally used for normal traffic flow, while the left lane is designated for overtaking. This practice helps maintain the smooth movement of traffic and ensures that vehicles can pass safely and efficiently. When overtaking, it's crucial to ensure it’s safe to do so, checking for oncoming traffic and making sure you have sufficient space to maneuver back into the right lane after passing. This action promotes safety on the road and respects the right of way for the vehicles that are already traveling in the right lane. Contexts such as making a U-turn, navigating road construction, or approaching a traffic signal may necessitate leaving the right lane, but these situations do not specifically relate to the overtaking maneuvers that require lane changes. U-turns can be made from designated lanes, construction might require driving in a different manner to avoid obstacles, and traffic signals generally dictate lane use based on the light and intended direction of travel rather than solely the need to pass another vehicle.
