Except as otherwise provided in this Chapter, every vehicle
stopped or parked upon a roadway where there are adjacent curbs shall
be so stopped or parked with the right-hand wheels of such vehicle
parallel to and within eighteen (18) inches of the right-hand curb.
No person driving or in charge of a motor vehicle shall permit
it to stand unattended without first stopping the engine, locking
the ignition, removing the key from the ignition, effectively setting
the brake thereon and, when standing upon any grade, turning the front
wheels to the curb or side of the street or highway.
On those streets which have been signed or marked by the City
Traffic Engineer for angle parking, no person shall park or stand
a vehicle other than at the angle to the curb or edge of the roadway
indicated by such signs or markings.
