An impact protection structure (200) includes an impact frame (215) and one or more impact bars (210, 212) connected to the impact frame (215) through one or more impact buffers (220). The impact buffers (220) are configured to linearly absorb an impact force (330, 332, 335, 336) over a predetermined displacement distance. The impact bars (210, 212) can include slotted holes (213) for receiving hinge pins (224) connecting the impact bars (210, 212) to the impact buffers (220). The impact frame (215) can be connected to a vehicle frame (115) in a manner that permits some deformation of the vehicle frame (115) without deforming the impact frame (215). One or more sensors (510) can be provided to detect impacts (330, 332, 335, 336). An impact alert signal (514) can trigger a drive-inhibit function (520) that removes torque from the drive motor. A manual override can permit an operator to drive the vehicle (100) during the drive-inhibit function (520) until the drive-inhibit function (520) is reset by authorized service personnel. Additional equipment can be retrofitted to the vehicle (100) using the impact frame (215).
