Can someone enlighten me as to the purpose of certain stretches on Motorway where these chevrons have been put and do they pick a particular section to paint them on?..I realise if you keep 2 chevrons apaprt you are probably sticking to the 2 second rule and leaving a safe gap from the vehicle in front of you,but have you ever tried to actually leave the 2 chevron gap? In my experiance a vehicle normally slots into the space you have left so what are you supposed to do slow down to get your correct gap again I dont think so…any one have views/comments feel free
I think they painted them because there was to much money in the ecconmy hopefully someday they’ll be paid for.
They are there to cause congestion with all the numpties braking for them and anyway can car drivers see as far as 2 chevrons ahead 
Anyone else notice that where ever they put these chevrons the traffic backs up on the approach? 
How long ago/old are they, they have taken them up in the N/W as they seem to cause more congestion 
Must be a bonus scheme or something, someone comes along with an idea, lets paint lines to try and reduce accidents, job done performance/great idea bonus paid 
, 5 years later someone says how about we take up the chevrons as they cause congestion as everyone stamps on the brakes when they see the first one’s and we have the famous phantom queue 
, lines removed job done another performance bonus paid out
Wait another 5 years they’ll put them back again 
As has been said some numpty gets in the gap you have left, I have tried to do it where it is marked on the road, but tend to give up in the end, if you keep backing off to allow for every prat that nips into the gap you have left, you will end up going backwards.

I often think that myself…
I’ve never seen anyone trying to ‘follow’ them. Everyone just drives 1 car length from the one in front as per usual.
and i thought they were to tell you which way to go.
i tried to keep 2 apart about three years ago… only to be told by plod not to bother as i was going 40 mph lol.
To stop them fighting. 
i,ll get me coat.
In my experience, most of these chevrons are on hills or the approach to them. Not as unusal as you think though, the right hand lane markings on a European motorway do the same job and the police will come and explain the error of your ways if you look like you are bunching up.
As we have moved to Europe.

I disagree, I think you’ll find they are usually found on straight and level stretches of motorway which tend to attract a high volume of traffic. When you can’t see what’s going on in front of you it often takes you by surprise when the car in front suddenly slams on and you can’t stop in time yourself. The idea, obviously, is to try and space you out more so that when the inevitable slamming on occurs, you can stop in time. Prime example of this is 29-Tibshelf on the M1 South. There’s ALWAYS some crunch happening along there in lane 3 because you can’t see what’s in front of you and there aren’t any reasons for the traffic to suddenly stop, hence why the crunches happen because people aren’t expecting it.
I will have to get my motor chipped I can do it on the over run but once we get on the flat I have to make it three or four chevrons

Yeah. Amazingly if you don’t drive up someones arse you can do that. Being in L1 where you’re supposed to be unless overtaking, there’s not many people going to dive into the space you’ve left. Open season to lanes to the right of you though.

You have just answered your own question
They are a reminder of the 2 second rule .
The typical stopping distance as a general guide at 70mph is 96 mtrs (315 feet) ( variable depending on your attention-thinking distance, the road surface,the weather conditions and the condition of your vehicle at the time. 
The idea of 2 chevrons = 2 seconds /100mtrs … chevrons being 50 mtrs apart , ( 1 roadside verge marker post apart = 100 mtrs ).
Usually laid in areas where there have been a high number of nose - tail shunt incidents.
As another poster mentioned, often on straight level sections of m/way. i.e. M6 Cheshire.
