If the Director finds that at certain times, or under specified restrictions, or at
designated places a person can so operate a motor vehicle so as to not interfere in
any way with the use of any beach, he may grant such person permission so to operate
such motor vehicle. Otherwise, a person shall not bring to or operate on any beach
any motor vehicle except as permitted by the Director, and subject to all of the conditions
which are a part of such permission. If permission to operate a motor vehicle is granted,
a person shall park such motor vehicle only in those areas designated by the director
for parking.
