What does a specific sign indicate if only buses can go?

• A. Traffic signal
• B. Parking restriction
• C. Bus lane only
• D. Pedestrian crossing

Answer: (C)

A sign indicating that only buses can go signifies that the area is designated as a bus lane. This is a special lane intended exclusively for the use of buses, allowing them to operate more efficiently and without interference from other types of vehicles. Bus lanes help in keeping public transport moving in congested traffic areas and enable quicker service for public transit users. The presence of such a sign means that other vehicles must not enter this lane unless otherwise permitted, ensuring that buses can maintain their schedules and contribute to the public transport system’s overall efficiency.

The other options, while relevant to road signs, do not pertain to the specific indication of a bus-only lane. Traffic signals generally regulate all traffic types, parking restrictions apply to areas where parking is limited or prohibited, and pedestrian crossings are meant for the safe passage of pedestrians. Each has its distinct purpose but does not imply that only buses are allowed to travel in that area.
