In a divided three-lane road with two-way traffic, when can a driver not drive in the center lane?

The correct answer is based on the specific conditions under which the center lane of a divided three-lane road is designated for use. In this context, the center lane typically serves as a turning lane or a lane for vehicles to pass, but there are clear regulations that govern when vehicles may utilize it.

The center lane may not be used for general travel purposes when it has a specific marking indicating its designated use. For instance, lanes marked specifically for right turns only prohibit drivers from traveling straight or using that lane for any other maneuver not permitted by the lane's designation. This ensures safety and helps maintain the flow of traffic by preventing confusion among drivers.

Understanding the rules regarding lane markings and their specific uses is crucial for drivers to ensure compliance with traffic laws and to navigate roadways safely. In contrast, while factors such as making a turn or encountering road construction can affect lane usage, they do not inherently prohibit driving in a designated center lane per se. Therefore, the focus is placed on the lane markings which dictate the appropriate use of that lane.
