Bump gate

A bump gate is a drive-through gate used in rural areas to provide a barrier to livestock that does not require the driver to exit the vehicle. By contacting the swinging bump gate with the front of a vehicle and then accelerating, the bump gate is pushed open, allowing the vehicle to pass. This requires some skill to avoid the gate swinging back and striking the vehicle. Accordingly, a bump gate is unsuitable for long vehicles.

The bump gate's self-closing mechanism consists of two cables mounted on the gate, and also on an elevated crossbar. The gate does not swing on a conventional hinge. Instead it is fastened to cylinders that encircle a post. When the gate swings open, the swivel action causes the cables to raise the gate slightly. After the vehicle passes through, gravity causes the gate to swing like a pendulum (parallel to the ground) until it settles in the closed position.

According to Bump N' Drive, the product does not require professional setup or installation. While not a common type of gate, it has been observed in several locations in West Texas.

In some parts of Texas, specifically west of San Antonio, a bump gate is synonymous with a cattle guard.
