Update: Driver Compartment (June 11, 2005)
The solar driver compartments must have all rough edges and pointed objects padded. Anything that could come in contact with the driver during a collision should be padded.
Update: Registration Deadline (May 27, 2005)

Clarification: Driver's License (January 28, 2004)
Question: What does the race consider as a valid driver's license?
Clarification: Crush Zones (February 27, 2003)
Question: We were wondering if the 15 cm of crush zone was something that had to be added to the frame of the car? Or if it is ok to use the frame, as long as the driver sits 15 cm away from the edge of the frame, and the frame provides needed protection.
Clarification: Crush Zones (October 27, 2002)
Question: I need references for the determination of safe zone construction for side, frontal, rear, and roll-over. The side impact zone, while least likely, is the one that worries me the most.
