UK’s Guide to Emergency Access and Egress on Motorways and Trunk Roads

‍

Ensuring efficient emergency access and egress on the UK’s motorway and trunk road network is critical for road safety, incident management, and minimizing delays. The GD 368 guide, published by National Highways, outlines infrastructure requirements to support emergency response teams and improve overall traffic management during major incidents.

‍

This blog explores the key provisions of GD 368, covering emergency access points, turnaround areas, and central reserve crossings—all designed to enhance road safety and emergency response efficiency.

‍

‍

Why Emergency Access & Egress is Crucial

‍

During major incidents such as collisions, vehicle breakdowns, or severe weather conditions, roads can become fully or partially blocked, leaving vehicles trapped. Without proper infrastructure for emergency access, these situations can lead to:

‍

• Delays in emergency response times
• Increased risk to stranded motorists
• Traffic congestion and secondary accidents

‍

GD 368 provides standardized solutions to ensure quick and safe access for emergency responders and efficient egress for motorists when required.

‍

Key Infrastructure Elements in GD 368

‍

1. Hard Standings for Emergency Responders

‍

Hard standings are designated areas where emergency responders can safely park and deploy resources. These locations are strategically placed near high-risk areas such as:

‍

• Congested junctions
• Frequent accident spots
• Weather-prone sections of motorways

‍

Design Considerations:

‍

• Must be large enough to accommodate emergency vehicles.
• Should provide easy access to both carriageways for rapid response.
• Must have adequate drainage to prevent water accumulation.

‍

2. Emergency Turnaround Areas (ETA)

‍

ETAs allow vehicles—especially emergency responders and trapped motorists—to safely turn around and exit a blocked road segment.

‍

Types of Emergency Turnaround Areas:

‍

• Within central reserves (for crossovers between carriageways).
• At junctions to enable controlled U-turns.

‍

Key Design Features:

‍

• Minimum width of 15m for vehicles to turn safely.
• Should be clearly marked but not accessible to unauthorized users.
• Must be free from standing water and designed for low maintenance.

‍

3. Central Reserve Emergency Crossing Points

‍

In emergencies, responders may need to cross from one carriageway to another. GD 368 recommends purpose-built emergency crossings in central reserves, secured with:

‍

• Lockable gates or easily removable barriers.
• A minimum width for vehicle passage at low speeds.

‍

Placement Guidelines:

‍

• At least 2 km apart to ensure effective access.
• Strategically placed near tunnels (430m to 2km from tunnel entrances).
• Integrated with existing maintenance crossings to maximize efficiency.

‍

4. Purpose-Built Connectors to Parallel Roads

‍

In some cases, direct emergency exits are required to connect motorways to adjacent local roads. These connectors help in:

‍

• Diverting trapped traffic onto an alternate route.
• Providing emergency service vehicles quicker access.

‍

Key Considerations:

‍

• Should have secure gates to prevent unauthorized use.
• Must be coordinated with local highway authorities to avoid congestion issues.
• Should be clearly marked with signage for emergency vehicle access only.

‍

Implementation of GD 368 in the UK

‍

Who Follows These Guidelines?

‍

The GD 368 guidelines are applied by:

‍

• National Highways (for England).
• Regional Operations Centres (for emergency coordination).
• Local Highway Authorities (to integrate with local roads).

‍

Integration with Technology

‍

• CCTV Monitoring: To oversee emergency routes and turnaround points.
• Automated Gates & Barriers: Allow quick responder access while restricting unauthorized users.
• Weigh-in-Motion Sensors: To detect overloaded or stalled vehicles requiring emergency clearance.

‍

Conclusion

‍

The GD 368 guide plays a vital role in improving road safety, emergency response times, and traffic management across the UK’s motorway network. By implementing strategically placed emergency access points, turnaround areas, and central reserve crossings, authorities can ensure swift incident resolution and safer roads for all users.

‍

As road networks expand, modernizing emergency infrastructure will be crucial in keeping UK motorways efficient and accident-free.
