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, open the gate, drive through, and then close the gate. 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 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.

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.
