Blocked sidewalks occur when obstacles prevent pedestrians from walking freely on the pathway. Common obstructions include parked vehicles, construction materials, or street vendors. These barriers can create safety hazards, forcing people to walk in the street, which increases the risk of accidents. In urban areas, blocked sidewalks can lead to frustration for those with mobility challenges, such as individuals using wheelchairs or strollers. Local governments often implement regulations to keep sidewalks clear, ensuring safe and accessible routes for all pedestrians, including those with disabilities or those using public transportation.
