Mine says 56mph or 90kmh exactly on the odometer, but measured on GPS it’s 55mph.Mine says the same and I still have plenty of artics flying past me!!!
Mostly owner drivers. Seems like if the limiter set speed is higher the truck is more valuable? 
If the alleged truck speed limit is now 60 on motorways/dual carriageways, why are the limiters still set to 56?

The legal speed limit has always been 60mph on motorways for as long as I can remember for trucks over 7.5ton.
The change from 40mph and 50mph to 50 and 60 for single and dual carriageways in England happened in 2015.
Vehicles between 3.5 and 7.5 ton were only required by law to have speed limiters fitted from 2006 iirc hence back in the day 7.5 tonner regularly travelled at motorway speeds or higher.
Then again I remember driving a 12 tonner that was brill cause it’s limiter was faster than an artic apart from when it saw a hill, a little Volvo FL with sleeper pod curtainsider.
Which I believe was set to 96.5kph from memory but it was quite a few years ago now.
I also spent plenty of times doing 70 to 80mph on motorways back in the day before speed limiters were mandatory on 7.5 tonners. Mainly cause my boss would always moan about my speed traces being off the 125kph charts all the time when he used to check them.
As for the 56mph or 90kmh it’s down to an EU directive and also I was always also lead to believe it’s down to fuel efficiency as 55ish is the most economical speed to drive at on motorways.

I found this. An interesting read: transportsfriend.org/road-t … -limiters/
Ours are getting reduced from 56 to 53 to save on fuel

Where I work we have a fleet of new Merc Actros’. There automatically default to economy mode, meaning the speed limiter will only set at 53, but you can press a button on the stork for the gear shift and change it to normal mode and you can set it to 56. Not that it makes much difference either way to me as I spend my nights trundling through the roadworks on the M6 so hardly reach either speed
