Boy, 13, dies following two-vehicle crash west of Swindon
A 13-year-old boy has died after a collision on the M4 westbound between junction 16 (Swindon) and junction 17 (Chippenham) on Saturday evening. According to Wiltshire Police, the crash, involving a Toyota RAV4 and a Renault van, happened at about 20:00 BST. A woman travelling in the Toyota sustained serious injuries and is being treated in hospital. Police said the drivers of both vehicles were not seriously hurt.
The motorway’s westbound carriageway was closed to allow emergency services to work at the scene. Traffic on the eastbound side was also held for around two hours to facilitate the attendance of air ambulances. National Highways later confirmed that all lanes in both directions had reopened.
Emergency response and road closures
The incident prompted a significant emergency response and widespread disruption for motorists on a key corridor for Swindon’s weekend traffic. Closures on the westbound side and temporary holds eastbound meant long delays for drivers heading towards Bath and Bristol, as well as those returning to Swindon. Police and highways teams managed the scene until the route was deemed safe to reopen.

Police appeal for witnesses and dashcam footage
Detectives are seeking witnesses and requesting any available dashcam footage captured in the area around the time of the collision.

Information provided by motorists and nearby road users is expected to form a key part of the ongoing investigation.
While full details of the circumstances have not been released, collisions on this busy stretch of the M4 frequently cause widespread disruption for Swindon residents and businesses. The motorway is a primary route for commuters, logistics movements and weekend travel, and even short closures can have a noticeable knock-on effect on routes through West Swindon, Royal Wootton Bassett and the A3102 corridor.
Travel impact and what motorists should know
Although the carriageway has reopened, drivers may continue to encounter residual delays as traffic patterns normalise. Those travelling between Swindon and Chippenham are advised to allow extra time and remain alert to any lane restrictions should investigators return to the scene for further enquiries.
- Allow additional time for journeys across the J16–J17 section while traffic flows stabilise.
- Check live updates from National Highways before setting off, particularly during peak times.
- Share dashcam footage with police if you were in the vicinity around the time of the collision.
Community response
News of a child’s death on a major route used daily by Swindon families will be felt across the community. As emergency services continue their work, the focus turns to supporting those affected and establishing how the collision unfolded. More information is expected as the investigation progresses.
Wiltshire Police have not released further details about the vehicles’ movements beforehand or any arrests. The force has reiterated its appeal for witnesses and for anyone with relevant footage to contact officers.
