M25 Motorway Chaos: Lorry Fire Causes Major Delays in Hertfordshire | Live Updates (2026)

Imagine being stuck in traffic for over an hour, all because of a single lorry fire on one of the UK’s busiest motorways. That’s the reality for drivers on the M25 in Hertfordshire today, where chaos has ensued after a lorry burst into flames, forcing the closure of a significant stretch of the motorway. But here’s where it gets even more frustrating: the delays are stacking up, with some motorists facing up to 60 minutes of standstill traffic. And this is the part most people miss—how a single incident can ripple through the entire transport network, affecting thousands of journeys.

Earlier today, a lorry caught fire on the M25 between junctions 25 (Waltham Cross) and 24 (Potters Bar), prompting police to shut down both directions of the motorway. Hertfordshire Fire and Rescue Service swiftly responded to the scene at 12:54 PM, and while the fire appears to be under control now, the aftermath is far from over. National Highways has reported delays of around 45 minutes, though some drivers are claiming even longer hold-ups.

But here’s the controversial part: Why does it take so long to reopen a motorway after an incident like this? Is it the cleanup, the safety checks, or something else entirely? Let us know your thoughts in the comments below.

For those stuck in the gridlock, a diversion route has been put in place. Motorists traveling anticlockwise on the M25 are advised to exit at J25, take the A10 southbound, and follow a series of roads including the A406 North Circular and the A1 northbound before rejoining the M25 at J23. It’s a lengthy detour, but it’s the only way to bypass the chaos—for now.

A photo shared on social media around 1 PM captured plumes of smoke rising from the motorway, a stark reminder of the disruption caused by such incidents. While the immediate danger seems to have passed, the question remains: How can we better prepare for and manage these events to minimize their impact on commuters? Is the current system efficient enough, or do we need a rethink? Share your opinions below—this is a conversation worth having.
