M4 Traffic Latest Update Today: Drivers travelling on the M4 motorway are experiencing major delays on August 6 after multiple incidents disrupted traffic across key sections of one of the UK’s busiest routes. A fresh multi-vehicle collision near Swindon has led to lane restrictions and heavy congestion, while recovery crews continue clearing an earlier fuel spill between J10 & J11 westbound.
The latest disruption comes only days after a major hay lorry fire forced a lengthy closure near Swindon, with traffic still recovering on surrounding roads. Motorists are being urged to plan, allow additional travel time and check live traffic updates before setting off.
