Which type of security feature stops vehicles from crashing through the doors of a building?

Bollards are robust physical posts or barriers specifically designed and strategically placed to prevent vehicles from driving through or impacting buildings, storefronts, or pedestrian areas. They act as a strong deterrent and physical obstacle against vehicle-based attacks or accidental collisions.

A receptionist is a person responsible for greeting visitors and managing access, not a physical barrier to stop vehicles.

A mantrap is a small room with two doors, where the first door must close before the second door opens, used for controlling pedestrian access to secure areas, not vehicles.

A turnstile is a rotating barrier used to allow one person at a time to pass through an entrance, also designed for pedestrian control, not vehicles.
