Every vehicle must meet the minimum roll cage requirements listed herein:

1. A roll cage is mandatory and must consist of four uprights joined together at all four corners of the top.

2. An "X" must be in place between the two rear up rights at the bottom, and then a diagonal bar may be put in place to joint the top and bottom horizontal bars.

3. Four horizontal bars running between the front and rear upright bracing required on the drivers’s side and may bow outward. Vertical bar pieces may be welded in place between the four horizontal bars.

4. Bars on the drivers side must be padded with roll bar closed-cell foam padding.

5. A minimum or three horizontal bars or an "X" is required on the passenger side.

6. A horizontal bar between the two front uprights at, just above, or just below dashboard level is required. If necessary plastic housing around the steering column shaft may be cut or removed to accommodate this horizontal bar.
