Parallel parking in TP is something like that if i never recall
wrongly:
Position your car around 0.5-1m (agar-agar) from kerb and some
distance away from the poles whereby when you turn your head you
can see all of them without blocking the other person parking in
front of you.
Engage reverse gear and once the front pole closest to your car is
at the right-top right of your rear windscreen as you are looking
backwards, full lock to left.
Look at your right blind spot mirror. Once the car is in line with
the 2nd behind poles you see, straighten your wheels. Then look
back again for safety.
Let the car reverse in a straight line until the bonnet has cleared
around halfway to three quarter from the front pole then full lock
to the right. Look behind again for safety.
Make sure you don't hit the behind poles. This is another reason
you should look behind. Coz your car no reverse sensor.
When you have reversed enough, depress clutch and brake, shift to
1st gear. Move forward and steer towards the left until car is
parallel with parking lot then straighten your wheels. You can full
lock to the left if you wish in this case but do remember to be
fast and fluid in your actions.
If necessary, reverse again to position your car in the centre of
the lot. Remember, everytime you reverse you must look
behind.
If I never recall any steps wrongly, its more or less like that.
However, what I, or your instructor said are only guidelines and
recommendations to use during your TP. In real life, there is never
a clear cut point when you should full lock or straighten your
wheels at what point of the parking. You have to depend on feeling
and understanding of your car dimensions. Best is if you can recall
how to parallel park like its second nature rather than memorising
the steps.
Anyway, good luck for your TP. Basically, on the main road, Ubi is
always a lot of cars one as long as the sun is up. But I believe at
2pm your tester won't be so strict.
