Texas Driver's License Knowledge TestTraffic Signs and SignalsMedium
A driver is traveling on a road with multiple lanes in the same direction. They observe a white diamond shape painted on the pavement in their lane. What does this marking signify?
- AThis lane indicates an upcoming exit ramp.
- BThis marking warns of a pedestrian crossing ahead.
- CThis lane is reserved for specific vehicles, such as HOVs or buses.
- DThis lane is for through traffic only, no turns allowed.
Show answer & explanationAnswer & explanation
Correct answer: C. This lane is reserved for specific vehicles, such as HOVs or buses.
A white diamond symbol painted on the pavement indicates a preferential lane, meaning it is reserved for specific types of vehicles, commonly High-Occupancy Vehicles (HOV), buses, or bicycles. Drivers should only use such a lane if their vehicle meets the specified criteria.
Why the other options are wrong
- A. Upcoming exit ramps are typically marked with guide signs and sometimes specific lane line markings, not a diamond.
- B. Pedestrian crossings are marked with white parallel lines (crosswalks) or other specific pedestrian symbols.
- D. Through traffic only lanes are usually indicated by arrows or 'THRU' markings, not diamonds.
Preferential Lane Markings (Diamond)
A white diamond symbol painted on the pavement designates a lane as reserved for specific types of vehicles, such as HOVs, buses, or bicycles.
- Indicates a 'special use' or 'restricted' lane.
- Commonly used for HOV (High-Occupancy Vehicle) lanes.
- Only vehicles meeting the criteria (e.g., 2+ passengers, bus) may use these lanes.
- Often accompanied by signs indicating the specific restriction.
Memory trick: White lines guide and divide, but a diamond means 'special ride'.
