Major M25 collision causes hours of severe traffic delays and emergency response

Thursday, 30 October 2025 5:06AM UTC

A serious collision involving two lorries on the M25 near Waltham Cross has led to extensive delays, emergency medical intervention, and ongoing lane closures, illustrating the motorway’s vulnerability to disruptive incidents.

A serious collision involving two lorries on the M25 near Waltham Cross has caused major disruption and severe traffic delays. The incident occurred on the clockwise carriageway between junctions 25 and 26, prompting the closure of the road for several hours to allow emergency response and clearance work. According to the London Ambulance Service, two individuals were treated at the scene, with one patient taken to hospital as a priority by road ambulance and the other airlifted by the East Anglian Air Ambulance. One of those injured reportedly suffered chest and leg injuries.

The crash resulted in extensive traffic congestion, with National Highways reporting around six miles of stationary traffic on the approach to the scene and delays exceeding 60 minutes, escalating up to 90 minutes according to some reports. The severity of the congestion forced authorities to implement diversions and close lanes to manage the flow of vehicles. Despite the incident being cleared by early afternoon—around 2:07 pm—lanes one and two remained closed for resurfacing work, prolonging delays for motorists.

The crash brought the clockwise carriageway to a standstill, with traffic moving only slowly even where speed restrictions were in place. The disruption was significant enough to affect journeys across the Essex border, with some sources estimating traffic delays of around two hours in peak congestion.

Emergency services acted promptly to respond to the incident. The East of England Ambulance Service deployed air ambulance support to assist in transporting the more seriously injured individual, highlighting the gravity of the situation. The London Ambulance Service confirmed their arrival shortly after the collision was reported around 8:33 am, and their swift intervention ensured both patients received urgent care.

While this incident involved two lorries, it should be noted that separate reports of a different, more tragic collision on the M25 near Waltham Abbey involved a lorry, a minibus, and a car, resulting in multiple fatalities and arrests. However, these appear to be distinct events occurring on different sections of the M25.

Motorists are advised to remain aware of ongoing lane closures and possible residual delays in the area, with National Highways recommending journey planning and patience as repair work continues. This event underscores the vulnerability of one of the UK’s busiest motorways to severe disruption when serious accidents occur.
