What does a white diamond symbol on the pavement indicate?

1. The lane is open for all vehicles

2. The lane is reserved for buses or high-occupancy vehicles

3. The lane is no parking

4. The lane is for bicycles only

The correct answer is: The lane is reserved for buses or high-occupancy vehicles

A white diamond symbol painted on the pavement is a designated marker indicating that the lane is reserved for buses or high-occupancy vehicles (HOV). This symbol serves as a visual cue to drivers, signaling that the specific lane is not just open for general traffic but is instead prioritized for vehicles that carry multiple passengers, such as buses or cars with a minimum number of occupants. This practice is intended to promote carpooling, reduce traffic congestion, and enhance the efficiency of public transportation. In contrast, other interpretations of pavement markings include parking restrictions or lane use, but those are indicated by different symbols or colors. For instance, "no parking" zones typically utilize different markings or signage, while bicycle lanes are usually identified with a bicycle symbol and often painted in green or with additional signs. Understanding these distinctions is crucial for safe and compliant navigation on the roads.
