One of the most feared maneuvers come driving test day is parallel parking. The high level of technical control required plus being on the road under pressure from road users culminate in making this tough for learners. This post is to specifically help clarify (as briefly as possible) to test candidates (and helping parents) what to do to pass this come exam day. More free tutorials (in greater detail and with videos) on all things driving related can be found here.
It's worth clarifying right from the off; the only thing you'll be marked on whilst maneuvering is control and observation. So by stopping regularly, the car's under control, and you can also observe effectively.
1 left, 2 right, 1 left. Left, right, left, 1, 2, 1.
That's as simple as anyone can possibly make it.
This works for my car, a Fiat 500. You may have to tweak it a little for other vehicles with different wheel bases and turning circles.
