Lorry overtaking ban

Additionally, there should be penalties for any car driver going so slow on the motorway that they cause HGV's to overtake them, grrr, that really annoys me.

Apparently, if the amount of freight on railways were doubled, this would only reduce the amount of lorries on the road by 1%.

I like GSi's interactive speed limiter!

Yep - they still have to get the good from the railway yards to the warehouses & shops!
perfect.
I do this kind of thing every day at work and it works a treat.
Ok my scenario is different because I work with planes, not trucks, but I'm sure the same principle applies.
Just as with the roads, there is a finite amount of space into which I can point my planes and as on the roads you invariable get 3-4 planes abreast of each other. This causes congestion in the air and is the reason why a lot of you are stuck in the terminal 30 minutes after you should have taken off.
The solution is to make things fly at the same speed and position them behind eachother in a stream rather than let them all fly at the speeds they want and get bunched up.
Ofcourse this does restrict some people (a 747 will cruise at mach .86 whereas an older 737 cruises at mach .74 - about a 70 mph difference), but the overall effect is to increase capacity.
The way we operate is to make it destination specific so that any aircraft inbound to Manchester will be issued a speed restriction over the south coast of England. Doing this ensures that by the time they get to the Hemel Hempsted/Luton area they are in such a line and thus freeing up all the extra space for other planes.
I realise that we cannot sequence traffic on our motorways according to destination, but you could substitute the word "destination" with "HGV" and acheive pretty much the same thing.

When the M6 northbound had road works between junctions 4 and 6 and a speed limit of 50mph rush hour journey times along this section were shorter than before or since the restriction was imposed
I'm all for it, the M11 and A14 (both mainly 2 lanes) are fecking nightmares, you get lorries side by side for miles on end trying to out drag each other while cars just stack up behind.

Sorry RHA - lorry drivers are not doing the rest of us a favour. They do it for money and they are being subsidised by car drivers (tax paid v. damage done to infrastructure).
No-one would argue if the trucks were making progress, but they're NOT. They're just sitting side by side for 10s of minutes (A74M south from Glasgow, M8 at Harthill, M80 heading into Perth).
Off the roads with them

The proposal relates to a 2 lane motorway. There is no mention of 3 lane motorways where lorries are already banned from lane 3.
In Holland, where they have motorway time related truck overtaking bans lorries are limited to 50mph and cars 75mph. Our theoretical maximum is 60 and 70 respectively. However speed limiters in trucks make this 56 and 70. The safety implications of a 44 tonne truck changing lane at a 25mph speed differential as in Holland is somewhat greater than the same manoeuvre with a 14 mph difference.
As stated previously in this thread the nearside lane will move at the speed of its slowest user. As sure as eggs is eggs there is going to be some Muppet in lane two crawling past at 2mph more holding everyone else up.
What will happen when, probably a BMW, in lane two stops because he failed to plan his exit strategy and now can
