Which highway feature provides advance information and warning about approaching driving situations?

• A. Traffic controls
• B. Lane markings
• C. Speed limits
• D. Pedestrian crosswalks

Answer: (A)

Traffic controls provide advance information and warnings about what’s ahead on the road. Signs, signals, and other devices alert you to upcoming conditions—such as curves, merges, construction, or changes in road layout—so you can adjust speed and position in time. Lane markings show where to drive and guide lane changes, but they don’t warn you about upcoming situations. Speed limits tell you how fast you may go, not what’s about to happen. Pedestrian crosswalks indicate where people may cross, requiring caution, but they don’t broadly warn about approaching driving conditions. So the feature that best gives advance notice of situations ahead is traffic controls.
