(a) Except as otherwise provided in this Code, 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 with and within eighteen (18) inches of the right-hand curb. Where no curbs or barriers bound any roadway, parallel parking is required unless otherwise indicated. This Paragraph shall not apply to a commercial vehicle when loading or unloading merchandise or passengers. (b) The Chief of Police may provide for the establishment of parallel or angle parking zones and cause highways to be marked with lines designating such parking spaces and requiring vehicles to park within such parking spaces. SOURCE: GC § 23132.1, enacted by P.L. 3-016:40 (July 14, 1955). 2025 NOTE: Past publications of the GCA included a manifest error stating the source of § 3403 was GC § 23232.1. This erroneous information has been corrected and will be omitted from future publications. Reference to the “Director of Public Safety” replaced with the “Chief of Police” pursuant to P.L. 17-078:1 (Dec. 12, 1984), which repealed language in GC § 5102 that established the Department of Public Safety, and reenacted language to establish the Guam Police Department, the head of which is the Chief of Police.
