“The reasons which the court gave for that finding are sufficiently clear. The drivers of V5 and V6 were able to stop, albeit abruptly. Although they should not have been driven in such a way as to make it necessary for them to come to an abrupt halt, their driving had nevertheless catered for the possibility of being able to stop without a collision – even if the vehicle in front came to a stop abruptly. By contrast Spr Sharp’s driving had not catered for that possibility.”
"It is inevitable that the separation of vehicles will reduce once braking commences. This will occur simply because, in a line of vehicles, any given driver will usually begin to brake only after the vehicle in front has begun to brake, rather than at the same time; thus inevitably there is a lag in successive drivers braking. If separation distances are appropriate the effect has no serious outcome. If following distances are inadequate each driver has to brake slightly harder than the driver of the vehicle in front and, sooner or later, a vehicle somewhere along the line will collide with the vehicle in front."
“Overall, it would seem very likely that at least some of the drivers in the convoy were leaving an inadequate gap between their vehicle and the one in front, i.e. less than 70 metres and probably less than the 2 second distance. The vehicles behind Mr Sharp would have faced extra difficulty because his vehicle, instead of continuing to move away from them, albeit whilst slowing, would have undergone a very substantial deceleration in the accident.”
