A breakdown leaves a lorry immobilised on the carriageway or shoulder of an insufficiently lit through-road within a built-up area, between sunset and sunrise. Which lights must remain on?

Correct answer

Position lights and, where applicable, end-outline marker lights.

The position lights and, where applicable, the end-outline marker lights must remain on. Article 105.1 requires this for a vehicle immobilised on the carriageway or shoulder. The option to replace position lights with parking lights concerns parking in line under Article 105.2; it does not generally apply to a breakdown immobilisation. Brake lights or end-outline marker lights alone do not replace the required lighting.
