According to Greyhound’s 2026 prohibited items list, you are strictly forbidden from carrying a pocket knife in your "Carry-On" luggage or on your person while on the bus. Greyhound maintains a safety policy similar to airline security; any item that can be used as a weapon, including knives of any size, multi-tools with blades, and even heavy-duty scissors, is prohibited in the passenger cabin. However, you can transport a pocket knife on a Greyhound bus if it is packed securely in your "Checked" baggage (the luggage stored in the compartment under the bus). It must be sheathed or securely wrapped to prevent injury to the baggage handlers. Before boarding, many major Greyhound stations now utilize security "wanding" or metal detectors; if a pocket knife is found on your person, you will be required to either dispose of it or move it to your checked bag before you are allowed to board. This policy is strictly enforced to ensure the safety of all passengers and the driver. If you are traveling to a destination where you need a knife for camping or work, simply make sure it is deep in your suitcase under the bus, and you will have no issues during your journey across the country.
