When parallel parking, the space you choose should be at least 1 1/2 car lengths long. This is because you need enough space to fit your car comfortably and leave some room for adjustment. Choosing a space that is only 1 car length may leave your car too close to the cars in front and behind, making it difficult to maneuver. Similarly, choosing a space that is 2 car lengths long may be too spacious and you may not be able to utilize the space effectively. 2 1/2 car lengths is too long for parallel parking as it may block traffic and make it challenging for other cars to pass by. Therefore, 1 1/2 car lengths is the optimal length for parallel parking.
