Bahrain's Traffic Law now names one specific road marking whose crossing is a criminal offence in its own right. Which is it, and what does crossing it carry?

1. The white edge line, carrying no penalty
2. The continuous longitudinal lines reserved for emergency vehicles — the yellow line — under the new Article 47 bis, carrying imprisonment of up to one month and a fine of BD 100 to BD 500, or either penalty
3. The centre line of any two-way road, carrying a BD 5 settlement
4. The chevron hatching at a merge, carrying a written warning
