When two forklifts are traveling in the same direction The forklifts should be at least?

When two forklifts are traveling in the same direction, they should maintain a safe distance of at least three to four forklift lengths apart to ensure sufficient space for maneuvering and to prevent collisions. This distance allows for reaction time in case one forklift needs to stop or change direction. Additionally, operators should always be aware of each other's positions and communicate effectively to enhance safety.
