Parallel parking. Parallel parking is a method of parking a vehicle parallel to the road (hence the term 'Parallel Parking'), in line with other parked vehicles. Parallel parking usually requires initially driving slightly past the parking space, parallel to the parked vehicle in front of that space, keeping a safe distance, then followed by reversing into that space.
Compared to navigating a parallel parking space, parking your car between two other cars in a standard parking space is relatively simple. There are two types of standard parking spaces. You will likely encounter both straight parking spaces and diagonal parking spaces in your driving career. There is little difference between the techniques used to park in these two types of standard parking spaces. Before you park your car, you must locate an open parking space.
