2 second rule on motorways
I feel that that at 70mph, the 2 sec rule between cars is an inadequate
time to avoid a pile up.I would say more like 4 secs. |

The rule is, drive so that you can stop safely in the distance you can see to be clear. Problem is, if you do, some prat will jump into the gap. We all have to cope with the standard of the worst drivers on the road. We don't have much choice. I've just watched a piece in iPlayer where a motorist bounced off the central barrier, risking the lives of all around him, just after joining a motorway. His excuse? He hit lying water at 75mph and lost it. "But at motorway speeds in the fast lane that you've just joined you don't have a chance to react," he said. Then bloody slow down, especially in rain, and when joining a motorway don't jump straight into the overtaking lanes, you pillock! Tone (Rant over. Of course, I am the perfect driver. Just the sort of driver that I used to hate when I was young because i now always get in the way at 55mph... except I don't wear a flat cap.) |

The problem with a rule of thumb is that is depends on the size of the thumb, and its location. Driving conditions vary, and failure to adapt driving behaviour accordingly is prima facie negligent. |

Two seconds is a pessimistic estimate of the perception and reaction time of the average driver and is intended to ensure that you don't drive into the back of the vehicle in front before you realise it is doing something other than continuing along the road at the same speed. It is not intended as a stopping distance, which would actually be close to a three second gap, using the Highway Code's average stopping distance table (stopping distance from 70mph = 315 feet : 70mph = 102 feet per second). If you prefer a larger gap, there is nothing to stop you leaving one. Colin Bignell |

Hmm, I recall coming on to the A45 dual carriageway and as I rounded the bend seeing a sea of brake lights ahead, so I hit my brakes (gently since I was doing about 80 on my slidecar chamine) and promptly started slewing across the road, so I let go of the brakes and had little trouble regaining control and slowing down more gently using the throttle. I had plenty of time to react and get under control before running out of lane width. It turned out a lorry load of offal had been shedding just quickly enough to spread all over the road for several miles. -- Steve O'Hara-Smith | Directable Mirror Arrays C:WIN | A better way to focus the sun The computer obeys and wins. | licences available see You lose and Bill collects. | http://www.sohara.org/ |

You simply drop back and leave the same gap behind that one. It doesn't make any significant difference to the journey time. Colin Bignell |

If the traffic on the motorway is travelling at that speed, then that's the speed at which you have to travel /to get on/. IME if traffic in the left hand lane is travelling at 70+ then there is bugger all traffic on the motorway anyway. Unless it was in Glasgow where the slip road from the A82 onto the M8 drops you into lane 3 -- Rab C. Nesbit The secret of life is honesty and fair dealing. If you can fake that, you've got it made |
