Final answer:
Angle parking refers to parking at an angle of 45 to 60 degrees with the front wheel touching the curb. It is a space-efficient method used in urban areas and requires precise maneuvering to align the vehicle within the designated parking area while minimizing traffic obstruction.
Step-by-step explanation:
When parking at the roadside, particularly in cities and other urban areas, it's common to perform a maneuver known as angle parking. Specifically, the question refers to the technique of parking at an angle of 45 to 60 degrees with the front wheel touching the curb. This method involves turning the vehicle from the travel lane into a parking lane at an acute angle, allowing more cars to park along the curb than with parallel parking. The precise angle can vary depending on the design of the parking space, but optimal angles are usually within the range of 45 to 60 degrees. When executed properly, the maneuver should result in the front wheel of the car gently touching or being very close to the curb, to prevent intrusion into the traffic lane and to align correctly within the designated parking space.
