Traffic conditions remain severely impacted across the A43 northbound and M40 Junction 10 interchange. National Highways confirmed that recovery teams are still working at the scene to remove the overturned lorry and safely clear the fuel spill.

A43 and M40 Traffic: What Happened?
The incident occurred when a large truck lost control and overturned on the A43 near the M40 Junction 10 roundabout area. The crash caused a significant fuel leak, which spread across multiple lanes and created hazardous driving conditions. Emergency services arrived quickly to secure the site, prevent fire risks, and control traffic flow.
Early reports suggest that the spill made the road surface unsafe, forcing immediate closure while specialist cleanup teams were deployed. Authorities are also investigating the cause of the crash, including whether speed, weather, or mechanical failure played a role.
