San Francisco installed 33 speed cameras at high-risk intersections, issuing over 30,000 warnings in the first month.Cameras were placed in areas with a history of speeding and crashes to enhance pedestrian safety.The cameras target vehicles travelling at least 11 mph over the speed limit, with fines starting at $50 and going up to $500.The camera program is still in the trial phase, aiming to reduce speeds in high-risk areas before full implementation.
