Title 43 Code of Federal Regulations (CFR): (plus) 8341.1(C) OHV operations in Closed Area, which carries a fine of $150 in most areas. 8341.1(b) OHV operations off designated routes (limited use areas) usually $100 fine. 8341.1(d), CVC (California Vehicle Code) 38020 OHV on public land w/o green sticker $50 - 38505 OHV on public land w/o helmet $35 - 38506 OHV on public land w passenger $35. There are others regarding spark arresters, etc that I don't remember the section.
Each Magistrate sets his own bail schedule (fines). I believe the 29
Palms Magistrate is Stephen Miller, who operates court out of the Park
HQ once a month. Miller's address is PO Box 6425, San Bernardino, Ca
92412, and ask for the Title 43 (BLM) bond schedule.
