**M25 Mayhem: Major Collision Causes Traffic Standstill** A significant collision on the M25 has led to severe traffic disruptions for thousands of motorists. The incident occurred between junctions 18 and 19, causing traffic to come to a complete halt. This chaos follows an earlier fire that forced parts of the M4 to close, compounding the travel woes for many. National Highways confirmed that traffic is currently stopped in both directions along this busy stretch of motorway. Debris has been scattered across the road from Chorleywood to the Chandlers Cross Interchange, further complicating the situation. According to reports, delays are expected to last for approximately one hour. A spokesperson for National Highways stated, "Traffic is stopped on the M25 clockwise between J18 and J19 due to a collision which has resulted in an overturned vehicle. The vehicle has been moved onto the hard shoulder. Debris is just in the process of being cleared. The carriageway will then be reopened. Delays are currently 60 minutes above normal travel time, thank you for your patience." Motorists are advised to seek alternative routes and remain updated on the situation as recovery efforts continue.
