1. Guardrail

A guardrail is a safety barrier installed along roads and highways to prevent vehicles from leaving the roadway—especially in dangerous areas like curves, bridges, steep slopes, or drop-offs.

  • Absorbs impact when a vehicle hits it.
  • Redirects the vehicle back onto the road.
  • Prevents cars from going into ditches, rivers, cliffs, or oncoming lanes.
