Trip hazard A trip hazard is any sidewalk condition that can cause a pedestrian to stumble or fall. Common examples include uneven slabs, raised edges, holes, and significant surface defects.
Trip hazards are one of the most common reasons sidewalks require repair because they increase the risk of pedestrian injuries. In NYC, hazardous sidewalk conditions may result in a DOT sidewalk violation or require corrective work to restore a safe walking surface. The appropriate repair depends on the underlying cause, such as settlement, tree roots, or deteriorated concrete.
