SAN FRANCISCO (KRON) -- Still figuring out California's new "Daylighting Law," a number of San Francisco residents were left confused Thursday morning after street curb markings were tampered with. Multiple street curbs adjacent to pedestrian crosswalks -- also known as "red zones" -- were illegally spray-painted, the San Francisco Municipal Transportation Agency confirmed. Two confirmed locations, according to SFMTA, are at the 18th and 19th Avenue intersections of Balboa Street. There were more on Cabrillo Street, although the location was not specified by the public transit agency. At this time, it is unknown who is responsible for tampering with the street curbs. SFMTA crews repainted the curbs by Thursday afternoon when KRON4 went to said areas. The incident comes after the state's Daylighting Law was announced in 2024. The law went into effect on Jan. 1, 2025 when SFMTA said it would begin to cite offenders with fines starting at $40. The law requires a 20-foot distance between parked cars and pedestrian crosswalks -- even if the curb is not painted red. If the curb is painted red, the distance between vehicle and crosswalk varies.

"Responding to these incidents is stretching our resources thin and causing confusion among residents," the SFMTA said in an email to KRON4. "To comply with the state’s daylighting law, we need to be focusing our limited resources where they matter most, which is most immediately in school zones to provide safe crossing to kids." This isn't the first time San Francisco street signs and markings have been tampered with. Last summer, a fake sign in Union Square outside the Dior store was displayed -- appearing to mock the California retail theft law at the time. The Dior store had been victim to theft multiple times. The sign, which read “stolen goods must remain under $950,” went viral on social media. In 2023, fake parking citations were targeting San Francisco residents. The SFMTA warned about scammers putting out fake QR codes across the city. "If people notice suspicious curb markings or signage, we encourage them to report it to 311," the SFMTA said.
