Anyone else noticing trucks and their restrictors....
Discussion
I don't know if this is just me, but has anyone who does a lot of motorway driving noticed that of late there seem to be an awful lot of trucks - UK registered ones for UK companies - that seem to be tanking along at waaay more than 56mph? Not noticed it before.
On the one hand it means they overtake other trucks quicker, but the downside is that they won't get back into lane 1 and there is always some poor sod with a 40 tonne artic driven by a suspected transvestite 3mm from his back bumper.

You don't want to be around the ports when the ferries from Ireland come in.
I've thought exactly this when I've seen it, but it's just normal UK ones - an Argos one this morning for example. Would appear someones figured a way around them and everyone is catching on.
Definitely found this recently- a nightfreight lorry was doing almost 70 on the M3 lastnight! At a steady 72 on the gps i only just managed to overhaul him- he did have to brake at one point going down a hill suggesting that his limiter wasn't working.
Coaches always seem to go way faster than lorries though- do they have different speed limits?

The limiters dont apply the brakes, only control the throttle, and 44 ton will push the engine beyond what the ECU is governing it at. Driver puts his foot on brakes to stay within his green lines. Always disconcerting when you think "No need to pull in after this truck I'll catch the next one quite quickly". And then you realise you're not catching it anything like as fast as you thought.
Not seen many doing 70 mind you. Some are noticeably faster than the general "pack".
The faster we do away with the limiter, and start to take advantage of other technologies to keep trucks safe the better.

A lot of older euro two engined 7.5 tonners have no limiter (like mine so I can travel at 60mph legal limit)and get there pretty quick
However my 32 tonner will cruse up hill and down dale at 56 easy all day
Legal limit is 60mph so your not goona get a tug if you get to run near 60 for a while.
Many companys like Waitrose and Sainsburys have some trucks (artics)limited to 52mph as fuel saving measure dependant on the area their working.
Go on the VOSA website there is a wealth of info on there relating to limiters and types of vehicle limits & useage.
On that subject however some vehicles which have a higher limter setting help to spread out the trucks a bit and stop some of the grouping up on the motorways.
I feel the limits should be graduated according to vehicle type so some of the smaller
trucks in the weight range can run at say 60 then rigid trucks up to 32 ton at 58 thus reduce max speed according to the MGVW with the heavty artics on 56-55.
Lets face even the humble motorist is limited to 70mph by way of law so you get grouping up and outside lane hogging there too.

I think the whole system could be improved by throwing limiters away if your truck is fitted with radar emergency braking, and lane departure warning, etc. We can even monitor blink counts and if the eyes are closed (driver sleeping) with a simple camera nowadays. By the time you introduce that little lot. Reducing trucks limit to 56-60 to improve safety seems pointless. Allow new trucks to go faster in exchange for better active safety equipment. Then newer trucks will avoid bunching with older trucks. And will only be limited by the same rules as cars.
