Which lights wouldn't be present at the back of a bus?

• A. White flashing strobe light
• B. Clearance and marker lights
• C. Alternating amber and red flashing lights
• D. All of the Above

Answer: (D)

At the back of a bus, the lighting focuses on standard rear signals that communicate braking, stopping, and presence to drivers behind. You’d typically see red tail lights, brake lights, a back-up light, and possibly reflectors. White flashing strobe lights aren’t part of typical bus rear lighting; they’re used on emergency or work vehicles to draw attention and aren’t standard on a bus. Clearance and marker lights mark the vehicle’s width and are usually mounted along the sides and sometimes the top, not as back-of-vehicle signals. Alternating amber and red flashing lights are reserved for certain warning or maintenance vehicles and aren’t used as the normal rear lighting on a bus. Because none of these light types are standard at the rear, the best answer is that all of the above wouldn’t be present at the back of a bus.
