Summary
Antioch bans overnight street parking wherever signs or curb markings say so under AMC § 4-5.1221.1. Nighttime is defined as 9:00 p.m. to 4:00 a.m. by default, though the posted signs can set a shorter restricted window at any specific location.
When authorized signs or curb markings have been determined by the City Traffic Engineer to be necessary and are in place giving notice thereof, no operator of any vehicle shall stop, stand, or park such vehicle during the hours so specified on the curb markings or signs. For the purpose of this section, NIGHTTIME shall mean the hours of 9:00 p.m. until 4:00 a.m., although the prohibition may apply to a shorter period of time, so long as specified on the curb markings or signs.
Full Breakdown
1, Nighttime Parking, does not impose a single citywide overnight parking ban; instead it authorizes the City Traffic Engineer to designate specific streets or blocks with signs or curb markings, and once those are in place, no vehicle may stop, stand, or park during the hours specified on them. for the purpose of the section, but it explicitly allows the posted restriction to cover a shorter period than that full seven-hour window, so long as the actual hours are printed on the curb markings or signs at that location.
except Sundays and holidays. 1 targets the overnight hours specifically, giving the Traffic Engineer a tool to restrict all-night street storage of vehicles on blocks where it becomes a problem, without a separate citywide ordinance for each street where it applies. The rule traces to Ordinance 317-C-S, passed June 10, 1976.
Violations & Fines
Parking during the posted nighttime hours where signs or curb markings restrict it violates AMC § 4-5.1221.1. Because the standard hours run 9:00 p.m. to 4:00 a.m. unless a shorter window is posted, drivers must check the specific signage on that block. A violation is an infraction or misdemeanor under § 4-5.1601, governed by Cal. Veh. Code Division 17 (commencing § 40000) with penalties set at Cal. Veh. Code § 42001.
