The Staten Island Ferry is a vital transit link and a popular free tourist activity, but it maintains strict safety and security protocols governed by the U.S. Coast Guard. First and foremost, no vehicles are allowed on the ferry; it has been a passenger-only service since the security changes following 9/11. Passengers are restricted from bringing hazardous materials, including gasoline, explosives, or uncontained flammable liquids. Smoking, including the use of electronic cigarettes and vapes, is strictly prohibited in all areas of the boat and the terminals. There are also restrictions on "loitering" or "continuous riding"; passengers are required to disembark at each terminal and re-enter through the waiting room for the next trip, which prevents people from simply staying on the boat for multiple loops. Large items like bicycles are permitted but must be kept in designated areas on the lower deck. Additionally, all passengers and their belongings are subject to random screenings by the NYPD and K-9 units, and "unattended baggage" will trigger an immediate security protocol and potential fine.
