2. Lanes are reserved for emergency vehicles

3. You can change lanes if it's safe to do so

The correct answer is: You can change lanes if it's safe to do so

A white line separating traffic lanes indicates that you can change lanes if it is safe to do so. This type of line typically signifies that the lanes are controlled within the same direction of traffic. Drivers are permitted to switch lanes, provided they check for safety and ensure there are no vehicles in their blind spots or in the lane they are entering. The presence of a white line helps facilitate organized movement, allowing drivers to maneuver safely between lanes when appropriate. In contrast, other types of lines, such as double white lines or solid white lines, might convey different rules regarding lane changes, either indicating that lane changes are discouraged or prohibited. Understanding the meaning of lane markings is crucial for safe driving and adhering to traffic regulations.
