Road number (F14) ”A road number is only given for roads in the number group 1–499. A sign with a dashed border indicates that the road is leading to the route with the number on the sign.”
Review of the options:
If you turn right you will come directly onto E20. – Wrong, since the border is dashed, you do not come directly out on this road.
If you turn right you will first come onto E20, then road 53 and lastly road 230. – Wrong, this is not necessarily true. It is probably possible to get to road 230 without having first driven on E20 and road 53.
If you turn right, you have the possibility of connecting to E20, road 53 and road 230. – Correct.
To come to E20, road 53 or road 230, you first need to go to the centre of town. – Wrong, it says nothing about this. It is more likely that there is an exit road to E20 before you reach the centre.
