For parallel parking, set cones 25 feet apart and 7 feet away from the curb. Place one cone in front of the car and two behind.
The most effective way to master parallel parking is to practice. Many behind-the-wheel driving tests use cones. To begin, set up the cones in a deserted lot or very quiet street with little traffic. A spot that is 5 feet longer than your vehicle is ideal for practice. Once correctly parked, your car is 5 to 8 inches from the curb, although in some states, 12 to 18 inches are allowed. You may live in a place where you never need to parallel park, so don't skip other important aspects of driver such as merging onto a highway.
