When you park a motorcycle next to a curb, it should be:

1. Parked at a 90-degree angle with the rear wheel touching the curb.
2. Parked at a 45-degree angle with the front tire touching the curb.
3. Parked like a car, with the front and rear wheels the same distance from the curb.
4. Parked at the left edge of the parking space so approaching drivers can more easily see the motorcycle.
