Article 6 Fire prevention
1. It is forbidden to throw anything into the road or its vicinity that could give rise to fire or, in general, pose a road safety risk.
2. Offences in this respect are considered as “serious offences”.
Throwing a lit cigarette end out of the window is deemed a serious driving offence with the loss of four licence points, unless any damage is caused by a resulting fire. In that case, this would then be considered a criminal offence resulting in a court case
