Unfit for 80: An Assessment of the Safety of England’s Motorways

The government has proposed raising the motorway speed limit to 80mph. This report looks at the evidence, including fresh analysis of the Foundation’s unique crash and engineering data and finds that currently motorways do not provide enough protection to drivers and car occupants to consider raising the speed limit. It outlines the negative economic effects of a higher speed limit, which include increased vehicle operating costs through higher fuel consumption; increased crashes and crash severity, resulting in raised crash costs; and the increased cost caused by delays from crashes. The report concludes with recomendations for key measures to deliver economic benefits and improve the safety of motorways.
