On 22nd October, l965, a two-lane stretch of the M.4 motorway between Slough and Maidenhead became fog bound and many vehicles were involved in multiple accidents between 5 p.m. and l0 p.m., when it was dark. A questionnaire was sent to 110 of the drivers of the vehicles involved asking them for their help in providing answers to a few questions. Fifty-three replied. Most of the drivers said they were in the fast lane and were attempting to keep vehicles ahead of them in sight. The drivers' estimates of the visibility and of the speed at which they were travelling differed considerably; and from their answers, their estimates for the average speed were 27 miles/h and for the visibility in two-thirds of the incidents under 12 yards. Some drivers said they were able to stop without colliding with the vehicle ahead but were then forced into it by the following vehicle. Most of the vehicles sustained only minor damage; the replies stated that thirteen people were injured, none of them seriously. (Author)
