Rumble strips are placed across the roadway to alert drivers of what?

• A. An upcoming hazard
• B. A stop sign ahead
• C. A speed limit change
• D. A pedestrian crossing

Answer: (A)

Rumble strips across the roadway are a warning device. They create a tactile and auditory cue so you notice you’re approaching something that could be hazardous or require you to slow down. The goal is to wake a sleepy or distracted driver and prompt caution because conditions ahead—like a sharp curve, a lane reduction, or another roadway hazard—may require you to adjust speed or be ready to react. It’s a general alert, not tied to a specific sign or a particular change like a speed limit or a pedestrian crossing, which is why the best description is that they alert you to an upcoming hazard.
