The driver is believed to have passed out whilst driving. The collision caused damage to approximately 400 metres of barrier. Lane 3 will remain closed throughout the day in both directions due to emergency repairs between junction 26 (Wellington) and junction 27 (Tiverton). A spokesperson for Highways England said: The vehicle spilt a large amount of diesel which was confined to lane 3 in both directions. The vehicle was recovered from the scene but lane 3 remained closed through the night for contractors to complete emergency barrier repairs and to treat the spillage. Contractors have advised that lane 3 will remain closed through the day to continue extensive barrier repairs.
