In January 2003, on a day known as White Friday, an enormous snowstorm brought the M11 motorway to a standstill and left drivers stranded in their cars for 18 hours. In the media storm that followed, the Highways Agency (HA) was heavily criticised for failing to prepare for snow and ice. Since that day, the HA have invested in a dedicated team of national traffic officers and motorway maintenance workers ready to react to weather events and deal with incidents.
