South Carolina Driver's Permit Practice Exam

What does a solid yellow double line in the center of the road indicate?

1. You may pass another vehicle.

2. You may not pass another vehicle and cross this line.

3. You can only pass during daylight hours.

4. It indicates a construction zone ahead.

The correct answer is: You may not pass another vehicle and cross this line.

A solid yellow double line in the center of the road indicates that you may not pass another vehicle and crossing this line is prohibited. This marking serves to help maintain safety on the road by preventing overtaking in areas where visibility is limited or where it is deemed unsafe to do so. The use of solid yellow lines suggests that there is a higher risk associated with passing, such as oncoming traffic or reduced visibility due to curves or hills. This measure ensures that drivers remain in their lanes to enhance safety for all road users. In contrast, other options suggest scenarios that do not apply to solid yellow double lines. For example, passing is strictly forbidden, which eliminates the possibility of passing only during certain times or in certain areas, and the line does not indicate proximity to a construction zone. Understanding these markings is essential for safe driving practices.
