About Daytime running lights, dipped beam and full beam: which statement is WRONG?
There is no 'prohibited inside a built-up area' in the book.
Dipped beam is mandatory at night, AND during the day when there is poor visibility (less than 200 metres).
The book explicitly names 'another road user (including a pedestrian)' — a pedestrian counts fully as oncoming traffic.
Daytime running lights stay on alongside dipped or full beam; you don't need to switch them off separately.
Explanation
trap: assumption of simultaneous lighting. Book p.184 - as soon as you switch on dipped beam, full beam or fog light, the daytime running light must be (automatically) switched off. It is a replacement, not an addition
