Emergency services declared a major incident at 2:15 PM after a multi-agency response including Hampshire Fire and Rescue, South Central Ambulance Service, and Hampshire & Isle of Wight Air Ambulance.
Forensic investigators from the Roads Policing Unit have cordoned off a 50-metre stretch of the eastbound carriageway as they piece together vehicle telemetry and dashcam footage.
| Agency | Response Time | Role |
|---|---|---|
| Hampshire Constabulary | 2 min | Scene security & investigation |
| South Central Ambulance | 5 min | Advanced paramedic & air ambulance coordination |
| Hampshire Fire | 7 min | Cutting & casualty extraction |
The closure has severed the primary freight route between London and the Southwest, forcing hauliers to divert via A34 and M4, adding up to 45 minutes to journey times.
💡 Pro Tip
If you’re caught in the diversion, use real-time traffic apps and avoid the B3084 through Ludgershall — it’s already gridlocked with emergency vehicles.
Highways England has deployed two incident support units with temporary lighting and variable message signs warning drivers of the closure extending until at least 8 PM.
Senior investigating officer Inspector Claire Davenport told reporters that preliminary data from the vehicle’s Event Data Recorder indicates the driver may have suffered a sudden medical episode before the crash.
She stressed that all possibilities remain under scrutiny while appealing for dashcam footage from motorists who passed the scene in the minutes before impact.
