Rules Clarification: Additional Roll Bar Per Rule 5.2.2 Question: For solar cars where the driver's head rises above the top of the solar car body, does the additional roll bar require the same minimum dimensions as the primary roll bar? Answer: The additional roll bar is designed to defect the array should it be pushed in the direction of the driver. It certainly can have a smaller diameter and thickness so long as it would withstand the pressure of a collision.
