Imperial Sand Dunes Recreation Area A new California State law was passed in July 2012 called AB 1595. AB 1595 defines what type of vehicles this law will apply to. As long as your sand rail is over 1,000cc and does not meet the other qualifications of an Recreational Off-Highway Vehicle (ROV), this new law does not apply. For more information regarding AB 1595 check out the California State Parks Off-Highway Motor Vehicle Recreation website:
