Which device is used to make a controlled entrance for vehicles?

1. Keypad

2. Magstrip Reader

3. Barrier Gate

4. Biometric Reader

The correct answer is: Barrier Gate

A barrier gate is specifically designed to provide controlled access for vehicles, making it the appropriate choice for managing vehicle entry and exit at various locations such as parking lots, gated communities, or secure facilities. Barrier gates typically consist of an arm that raises and lowers to allow or deny vehicle passage, ensuring that only authorized vehicles can enter or exit the premises. While keypads and biometric readers can be utilized for access control, they are better suited for pedestrians entering buildings rather than for vehicle management. A magstrip reader also serves as a method for reading magnetic stripe cards, which might be used in an access control system but does not physically manage vehicle entry like a barrier gate does. Thus, the barrier gate stands out as the most effective device for making controlled entrances for vehicles.
