Teaching parallel parking requires patience and practice. Start by explaining the steps clearly, then demonstrate the maneuver yourself. Next, find a quiet area with plenty of space and use cones or boxes instead of actual cars. Guide the learner through each step, emphasizing reference points and when to turn the wheel. As they improve, gradually reduce the parking space size and introduce real parked cars. Remember, mastering parallel parking takes time, so be patient and offer plenty of encouragement.
