What is the primary purpose of rumble strips?

• A. To alert drivers that they have left the travel lane or are approaching a stop sign or signal.
• B. To alert drivers that they are approaching a school zone.
• C. To slow traffic through legal speed.
• D. To guide vehicles into a parking area.

Answer: (B)

Rumble strips are rough grooves in the road that you can feel through the steering wheel and hear through the tires. That vibration and noise are meant to wake a driver and grab attention, especially in places where a moment of inattention could be dangerous. In school zones, where children may unexpectedly enter the roadway, this tactile-audible cue helps you notice you should slow down and be extra cautious. So, the primary idea is using the strips as a clear alert in high-risk areas to reduce speed and increase awareness. They aren’t primarily about guiding you into a parking area, nor are they a universal tool to instantly enforce a specific legal speed everywhere, and while they can accompany other signals, their fundamental purpose is to alert you to upcoming conditions that require caution—such as a school zone.
