DIAGRAM 954

Diagram 954 – Buses Excluded from Restriction or Prohibition Conveyed by Associated Sign

The Diagram 954 road sign is a regulatory sign used to indicate that buses are exempt from a specific restriction or prohibition imposed by an associated sign. This sign ensures that while general traffic may be restricted in a certain area, buses are permitted to pass, supporting public transport accessibility and efficiency.

This sign is commonly installed in bus lanes, bus-only roads, restricted zones, and areas with traffic regulations that permit public transport access. It helps clarify that the restriction does not apply to buses, facilitating smoother transport operations.

Sign Meaning and Usage

The Diagram 954 sign features black text on a white background within a black-bordered rectangle, ensuring high visibility and clarity. It is used to inform drivers that the prohibition imposed by an associated sign does not apply to buses.

Key applications of this sign include:

• Allowing buses to use restricted roads to maintain efficient public transport routes,
• Ensuring compliance with bus lane regulations by clearly stating permitted exemptions,
• Supporting bus priority measures to reduce congestion and improve travel times,
• Providing clarity for other road users to prevent unauthorised vehicle access in restricted areas.

This sign is typically placed below a primary restriction sign, such as a ‘No Entry’ or ‘Motor Vehicles Prohibited’ sign, to modify its meaning and indicate bus exemption.

Importance of Diagram 954 for Traffic Regulation

1. Maintains Public Transport Efficiency – The sign ensures buses can operate smoothly even in restricted zones, improving commuting reliability.

2. Prevents Unauthorised Use – By clearly stating that only buses are exempt, the sign discourages unauthorised vehicles from misusing restricted routes.

3. Reduces Traffic Congestion – Facilitating bus access helps encourage public transport use and reduces overall traffic in busy areas.

4. Enhances Road Safety – By controlling which vehicles can enter restricted areas, the sign helps reduce conflicts between different road users.

Placement and Compliance Regulations

The Diagram 954 sign is regulated under the Traffic Signs Regulations and General Directions (TSRGD) in the UK. It must be positioned in conjunction with the main prohibitory sign and installed in locations where bus access is required.

For effective use, the sign must be:

• Placed below the primary restriction sign for clear understanding,
• Clearly visible to approaching motorists to ensure compliance,
• Maintained in good condition to avoid confusion,
• Enforced through local traffic regulations to prevent misuse by unauthorised vehicles.

Local councils and transport authorities are responsible for installing and maintaining these signs to support public transport efficiency.

Key Considerations for Road Users

• Only buses are permitted under this exemption.
• Unauthorised vehicles must adhere to the associated restriction.
• Other road users should be aware of bus movements in these areas.
• Report damaged or unclear signage to the relevant authorities.
• Follow additional local regulations where applicable.

Related Signage and Variations

The Diagram 954 sign is part of a broader category of regulatory signage aimed at managing traffic restrictions efficiently. Other similar signs include:

• Diagram 954.2 – Local Buses Excluded from Restrictions, which specifies that only local bus services are permitted,
• Diagram 954.3 – Buses and Cycles Exempted, allowing both public buses and bicycles access to restricted areas,
• Diagram 620 – Except for Access, which permits vehicles needing access to enter otherwise restricted zones.

Each of these signs serves a crucial role in ensuring smooth and efficient traffic management while prioritising sustainable and public transport options.
