Emergency services are dealing with a three-vehicle road traffic collision on the M4 tonight (Tuesday).
Fire crews were called to extinguish flames which resulted from the crash on the motorway westbound between junctions 14 (Hungerford) and 15 (Swindon).
The route remains open via one lane past the scene – which is causing significant delays.
Wiltshire Police has confirmed that nobody was injured in the incident and recovery work is underway.
