Artikel 34

1. At level-crossings equipped with gates or staggered half-gates on either side of the railway line, the presence of such gates or half-gates across the road shall mean that no road-user may proceed beyond the nearest gate or half-gate; the movement of gates towards a position across the road and the movement of half gates shall have the same meaning.
2. The showing of the red light or lights mentioned in Article 33, paragraph 1 sub-paragraph (a), of this Convention, or the operation of the sound signal mentioned in the said paragraph 1, shall likewise mean that no road-user may proceed beyond the stop line or, if there is no stop line, beyond the level of the signal. The showing of the amber light of the three-colour system mentioned in Article 33, paragraph 1 (a) (i), shall mean that no road-user may proceed beyond the stop line or, if there is no stop line, beyond the level of the signal, unless the vehicle concerned is so close to the signal when the amber light appears that it cannot safely be stopped before passing the signal.
