If the orange and white stripes on a barricade slope downward to the left, which side should traffic pass?

Answer: B — Left

When the orange and white stripes on a barricade slope downward to the left, it indicates the direction that traffic should pass. The design of the stripes serves as a visual cue for drivers, where the downward slope directs attention towards the safe side. In this case, the left side is the intended path for vehicles to travel safely past the barricade. This method of using sloped stripes is part of traffic control measures to clearly indicate detours and align drivers' expectations regarding road conditions and obstructions. Relying on the universally recognized pattern of these markings helps maintain order and safety in work zones, guiding motorists effectively away from hazards. The inclination of the stripes directly indicates that the left side is the safe passage, thus ensuring clarity in temporary traffic control scenarios.
