Correct!

You're waiting to turn right at the end of a road. What should you do if your view is obstructed by parked vehicles?

Stop and then move forward slowly and carefully for a clear view
Correct answer
Move quickly to where you can see so you only block traffic from one direction
Wait for a pedestrian to let you know when it's safe for you to emerge
Turn your vehicle around immediately and find another junction to use

DVSA theory test explanation

At junctions, your view is often restricted by buildings, trees or parked cars. You need to be able to see in order to judge a safe gap. Edge forward slowly and keep looking all the time. Do not cause other road users to change speed or direction as you emerge.
