A crash barrier is a safety structure designed to prevent vehicles from straying into dangerous areas like oncoming traffic or steep drops. Think of it like a bodyguard for cars on the road. 🛡️ It absorbs the impact of a collision, reducing the severity of accidents. Unlike a regular fence, it's built to withstand significant force. Imagine it's the last line of defense on a precarious mountain road. It's not just about stopping; it's about redirecting energy.
