The frequency and duration of thick fog (visibility less than 200m) in Great Britain has been analysed for the period 1958-67. The highest mean annual number of days with thick fog at recording sites was 17 at 0900 GMT at Watnall (Nottinghamshire). Generally, thick fog was found to be relatively infrequent, patchy, rarely widespread and of short duration. Four thick fogs of twenty-four hour duration on weekdays reduced traffic flow by about 20 per cent. The numbers of fatal and serious accidents and casualties were reduced but slight accidents and casualties increased significantly. (Author)
