The bus plate is placed directly under a main traffic sign to show that the rule targets buses rather than general traffic. It is often used near bus lanes, terminals, stations, and priority junctions where bus operations must remain reliable and safe. The plate does not extend the rule to lorries or passenger cars unless this is clearly shown on additional signs.

The OB-12 sign means that a specific traffic rule, lane, or area is exclusively for public transport buses or coaches. If you are driving a car, motorcycle, or lorry, this sign indicates that the rule or area does not apply to you, and you should follow other applicable traffic regulations or use a different route.
You're most likely to see the OB-12 sign in urban areas near bus lanes, bus terminals, public transport hubs, or on streets where bus movements need to be managed specifically. It helps to ensure that buses can operate smoothly without being impeded by other traffic.
If you see the OB-12 sign and you are driving a car, you should understand that the restriction or designation shown by the sign is for buses only. This means you are generally not permitted to enter that lane or area, or you must comply with different rules than those specified for buses. Always look for alternative routes or follow general traffic signs.
The scope of the OB-12 sign can sometimes vary based on local policy or the specific design of the accompanying signs or road markings. While it generally targets public transport, it might apply to all coaches or specific types of buses as indicated. Always check for additional information or context provided by other signs.
The OB-12 sign is straightforward: it means 'buses only'. The potential 'trap' in an exam could be confusing it with signs that apply to all vehicles or signs that indicate a bus stop. Always carefully read the question and observe the sign's specific meaning – in this case, exclusive application to buses.
