Image 2 and 3 show that you are parked behind a vehicle and if you were to set off you cannot see oncoming cars and that makes it unsafe.
On test there will not be a car in front of you. But you are going to carry out a reverse manoeuvre as if there was a car in front of you.
The examiner will now ask you to reverse 2 car lengths and then rejoin traffic. Now you can see why it was important to park straight. If you are straight you should need to do almost no work with the steering wheel.
Firstly, you will need to do your POM (Prepare, Observe, Move Off) rountine making sure you are in Reverse gear. Your observations will also be different. You need to check the pavement to the road and final road (Right shoulder to left and final left). Remember the danger now comes from in front and your left shoulder.
If it is clear reverse in a straight line for 2 car lengths. Dont worry if you cannot guess 2 car lengths, the examiner wont get a tape measure out! Your observations at all mirrors and over shoulders can be difficult, so go slowly and stop if you need to.
If it is not clear on the right hand side of the road do not set off. If a car comes on the right hand side of the road as your are reversing you must stop, and set off when it is clear.
If a car comes from behind you on the left you must decide if that car is going to be close to you. If is, do not set off or stop if you are part way through your reverse. If there is lots of room you can contine. The width of the road or parked cars are possible reasons that cars approaching from behind you may get close.
Having reversed back 2 car lengths there is no need to secure the car unless you are going to be waiting a long time to set off due to a lot of traffic.
Start your POM rountine again completing the observations from right shoulder to left. Make sure you are in 1st gear (or D). Set off when it is safe. Signal left if someone will benefit. Steer gently again over to the left, there is no rush to get back to the left hand side of the road so you dont need to apply lots of steering.
DIFFERENCES BETWEEN AUTOMATIC CARS AND MANUALS
When completing this manoeuvre you must keep the car slow and the steering fast. By now you should know how to keep the car slow crawling.
