Why might your turn assist system emit a warning?

Your answer is correct. The turn assist system is designed to warn you if a cyclist is present next to the right side of your vehicle. This helps prevent accidents, especially when making right turns, since cyclists can be in your blind spot. The system does not usually warn if you cross a lane boundary line or if you turn too quickly; its main function relates to detecting vulnerable road users like cyclists in critical positions. Remember to check your mirrors and be aware of cyclists even if your vehicle is equipped with such assistance systems.
