A significant incident involving a multi-vehicle crash and subsequent fire has caused widespread traffic disruption on the M1 motorway. The event, which occurred on the southbound carriageway, led to a complete closure of a substantial stretch of the road, creating lengthy tailbacks and delays for motorists. Emergency services and traffic management teams were promptly deployed to the scene to address the situation.

Traffic Management and Delays
National Highways East confirmed the closure and warned of accumulating traffic. Reports indicated substantial delays, with one account mentioning six miles of tailbacks and 45-minute delays expected near Junction 15. Traffic officers were actively involved in traffic management.

Conflicting Information on Duration and Location
While the primary reports focus on the southbound closure between J15 and J14, other reports indicate similar incidents occurring at different times and locations.
Article 3 mentions a closure on the M1 southbound between J21 (near Leicester, M69) and J20 (near Lutterworth) due to a crash involving three vehicles and a subsequent fire. This suggests a separate, possibly earlier, incident.
Article 4 describes an incident on the M1 northbound from north of Junction 28 down to before Junction 27, which caused heavy traffic during an evening rush hour. This incident is noted as having all lanes reopened, with traffic easing.
Article 5 details long delays on the M1 Northbound from J41 (A650, Carrgate) to J42 (M62 J29, Lofthouse) due to a fire. This situation was later reported as cleared.
Expert Analysis and Official Statements
Official statements from National Highways confirmed the closure and warned of traffic build-up. No specific analysis or expert commentary on the cause of the crashes was immediately available in the provided reports.

The core of the reported incident involves a multi-vehicle crash and fire on the M1 southbound, necessitating a closure between J15 and J14 and causing significant traffic disruption.
Conclusion and Implications
The primary event on the M1 southbound between J15 and J14 represents a significant disruption to road users. The presence of a fire alongside a multi-vehicle crash necessitated a comprehensive emergency response and closure of a key section of the motorway. The existence of other reported incidents at different locations and on different carriageways, while potentially related to general traffic conditions, highlights the complexities of motorway network management during periods of severe weather or multiple simultaneous events. Further investigation would be required to determine if these other incidents are linked or are entirely separate occurrences.
