Final answer:
When operating a forklift and encountering a stopped vehicle in your path, the safest action is to stop and wait for the vehicle to move to ensure workplace safety and prevent accidents.
Step-by-step explanation:
When approaching another vehicle stopped in the path of the forklift you are operating, the safest course of action is to stop and wait for the other vehicle to move. It is important to prioritize safety and avoid any potential accidents in the workplace. Although sounding the horn is a method to alert the other vehicle, it does not guarantee that the path will be cleared promptly. Proceeding with caution may still present risks, especially if the other vehicle's intentions are not clear. Reversing to find an alternative route could be considered if waiting is not an option, however safety should always be the first consideration.
