What do double-dashed broken yellow lines indicate?

Double-dashed broken yellow lines indicate that the lane is reversible, meaning that the direction of traffic in that lane can change based on the time of day or traffic conditions. These lines are often used in areas where traffic flow needs to be adjusted to accommodate peak traffic periods, allowing lanes to be designated for inbound or outbound traffic as necessary.

Understanding that double-dashed lines signal reversible lanes is crucial for safe driving, as it informs drivers that they must pay attention to signs indicating the current traffic flow direction. This awareness helps them make informed decisions when merging or changing lanes.

The other options do not reflect the significance of double-dashed broken yellow lines. For example, while slowing down may be a good practice in certain situations, it is not a rule indicated by these specific line markings. One-way traffic typically is marked by solid lines or arrows, and no parking zones are indicated by different types of signage or pavement markings. Therefore, recognizing the purpose of double-dashed broken yellow lines is key for navigating reversible traffic lanes effectively.
