Cycling on highways poses significant risks due to high-speed traffic and multiple lanes, which can be dangerous for cyclists. While some highways permit biking to support commuters, the potential for accidents remains a concern. Cyclists must exercise caution and follow traffic laws to minimize risks. Prohibited highways, such as the Garden State Parkway and New Jersey Turnpike, are designed to prevent such dangers by restricting bicycle access. Residents relying on bicycles for commuting should plan routes carefully to avoid restricted areas and ensure their safety.
