A Highways England spokesman told the BBC: "Safety is our first priority and we monitor our network for locations with a high risk of wrong-way driving.

"We're actively reviewing [this] in light of the recent M40 incident. We are also undertaking wider international research examining the effectiveness of mitigation measures."

Yesterday friends and neighbours paid tribute to John Norton, 80, and Olive Howard, 87, both from High Wycombe who were travelling in the Subaru Forester that was towing the caravan.

The couple were described as friendly but quiet and neighbours said little was known about them. 

Earlier this month tributes were paid to 'thoughtful, loyal and friendly' former soldier Stuart Richards, from Stockport, who also died in the crash.
