In which of these night-time situations may a car no wider than 2.10 metres use position lights without dipped or main beam?

Correct answer

When legally parked on a shoulder outside a built-up area.

When legally parked on a shoulder outside a built-up area. Article 105 requires position lights for a vehicle immobilised at night on the carriageway or shoulder and clearance lights where applicable. This does not permit parking on every shoulder. A car travelling at night cannot use position lights alone merely because the road is adequately lit: prescribed driving lights are also needed.
