Discussion
Yesterday I had a relaxing drive back from work in Newcastle, doing 67mph on the cruise control. Coming west along the M62, a few miles east of Saddleworth, I approached a Morrison's HGV, 50 yards from it I moved into lane 2 to overtake and it started pulling away from me!
It must have been doing about 70-75mph in lane one, downhill.
Now I don't have any issue with this at'awl, but this changes my ideas of how HGV speed limiters work. So how do they work? How did this big beastie get so far past 56mph?

its much easier/safer to drive without a limiter isnt it? i hated them when i was driving coaches too.
how often does a limiter leave you stuck outside/alongside another truck when it decides to kick in?
worst one was a coach i drove that the limiter kicked in at 64mph but cut the engine till you dropped to about 54mph - perfect if the road angle varied & you didnt keep your speed control perfect while passing a truck.

Actually, I find its a different mind set required now. Our vans are limited under the new EU bend over and smile laws. Overtaking is now a game of wait and see after a game of catch. Obviously we have caught up with a slower limited vehicle. Its now a game of wait and see when we can pass the quickest. Hills offer us the best chance as we have no problem with them compared to a laden HGV.how often does a limiter leave you stuck outside/alongside another truck when it decides to kick in?

Ive been passed by Irish plated trucks doing 80+ and the big rigs in the USA really really fly!
yep those paddy wagons fly.. no limiters (not in the EU) 
I've lived north of Newbury just off the a34 for around 10 years and i've never seen a truck doing 80mph.
Speed limters are road safety nightmare, cause loads of tension to other road users and worse of all vehicles are limited to speeds UNDER that they are legally permitted to do under the highway code, should never have been allowed

Most of them do operate the brakes downhill 
No they don't, the cruise control brings the exhaust brake on, at 56mph he would only be doing 1400 rpm so if he is fully loaded he would get no engine braking thats why his speed crept up on the down hill.He can obviously apply the exhaust brake while on the limiter (by using either the foot or hand control) but the limiter itself won't apply the EB.

I can only say what I see. I drive it every day and there is one particularly big dip and many times I have been toddling along with cruise set at ~70 on the GPS being passed by HGV's going considerably faster than me. I have to admit this is quite rare, by far the majority are doing about 70 and pacing me.bigdods said:

Morissons, Tescos, Asdas, bloomin pain in the @rse! It was most probably a Morissons trailer being pulled by a contractor.
Today I received my brand new Scania. It stays at a steady 56. Bit peed off really as the one I had pior to this (for 4 years) did aproximately 58mph. It was a darn site safer I can tell you, being able to overtake other trucks averaging between 54-56ish. (you can only understand this if you have driven a vehicle with a limiter!)
BTW - fuse 18 = Scania limter bypass. wink wink
