The Golden Rules of Parking
If you're looking for a parking space, don't turn into a kerb-crawler with a tail of impatient motorists trailing behind you. Indicate and pull over until the road is clear.
When you find that elusive space, indicate immediately to signal your intention. With any luck other motorists will pass you, leaving you to perform your manoeuvres in peace. If someone waits patiently for you to back into a parking space, acknowledge their courtesy with a wave of the hand.
Never, ever steal into a parking space when another motorist is already indicating their intention to park there.
Tuck yourself into the kerb (avoid mounting the kerb as this imay obstruct pedestrians, wheelchairs, buggies etc.).
Leave adequate room to the front and rear for adjacent motorists to easily manoeuvre. Boxing someone else in is the height of bad manners.
Check that you are not blocking driveways, causing an obstruction, or endangering pedestrians or other motorists in any way.
Check parking regulations and ensure that you have paid up and displayed stickers clearly and that you are parked legally.
Don't even think about poaching disabled bays or parking in residents' permits only spaces. You are not entitled to do this - even if it is only for a few minutes.
Finally, if you see someone making a second or third attempt to squeeze into an awkward space, don't display your derision (blowing your horn is just rude). Remember this could always happen to you.
