When can you carry passengers on a forklift?

Carrying passengers on a forklift is generally prohibited unless the forklift is specifically designed for that purpose, which includes having extra seating and seatbelts installed. This design ensures the safety of the passengers, as forklifts are primarily built for lifting and transporting loads, not people. When a forklift is equipped for passenger transport, it follows safety standards that help prevent accidents, ensuring that both the operator and the passengers are secure during operation.

The other options do not address safety adequately. Space availability does not equate to safety for passengers, as forklifts can be operated in a way that is not compliant with safety regulations. Weight limits may be relevant to the forklift's load capacity but do not provide a rationale for carrying passengers. Finally, the availability of other vehicles is not a valid reason to compromise safety on a forklift. It is crucial to adhere to guidelines established to ensure the safe operation of lifting equipment.
