I’ve tried some searches, but cannot find any thing about it. We’ve recently been hearing at work that when trucks are being recalibrated now all of them are being set at lower speeds (54 or 55) and that its coming in across the board, so to speak.
It doest sound right to me, I thought trucks were all varied to some degree to stop roads being clogged up by everyone travelling at the same speed.
Plus why have a 60 limit if they all have to be set much lower than even 56.
Is this just a local rumour, or is there anything in it?
Yes limit is 60 mph. In Europe it’s 90kmh..hence why there set to 56 mph which equates to 90mph. Just makes manufacturing easier save setting limits on UK bound trucks different.
As for it being lowered who knows .
seems a bit pointless if that’s what there doing.
1 mph slower won’t really add much difference to your working day .
Maybe it’s for emissions reasons?
1mph is about 20-25 minutes over a working day. So kinda is a big deal.
Often the old-bold-pros from the earlier era would have their favorite wagon at 58-59mph with some companies, then after a time a new boss or under-boss would hamstring it to 50 - 54mph for various reasons (usually because they were tight AF on the fuel). The problem is on some wagon makes you can actually mess up the engine in 11th or 12th gear if the vehicle isn’t going ‘fast enough’ and Scanias are finnicky about this (I am told).
No need to reach for a calculator here.
Going flat out, all the way, (not at all realistic) with one mph difference for ten hrs, there will be ten miles difference.
About 11 or 12 minutes.
In the real world, where vehicles do not accelerate from stop to max in half a second, and stop instantly, it is a lot less.
No need be picky about it all. Only way it would make a difference is if you were going flat out say Aberdeen to Manchester way. Then it might but then again you don’t go flat out all the time anyway. In real world you’d never notice the difference between 54 or 56 mph
Our 25 plate xf sits at a respectable 58. And that’s come calibrated from Daf. Handy for getting past others sometimes but yeah in the real world not much difference to 55/56.
I’d say if they’ve been set much lower its at somebody’s request.
Our 25 plate DAFS all came with “eco” tyres from new. Not a single one did more than 30k km before needing replacing but by God they go like a scalded cat being as they were calibrated with tyres with 6mm of tread and have now got beefy tyres on.
58mph is flying. Our firm had one unit (an older one) which had been ‘tweaked’ back to 60MPH, but after it was discovered, the steady old hand of the drivers always got it, as he wasn’t a flat-out merchant.
Used it for the night trunk last night. Came in handy. Cullina clown was trying to push me down the a500, despite being able to just go by. Got on the m6 and he was straight out to overtake. Indulged him at 55 for a mile or so then lit the afterburners when he got alongside . Childish but gave me a chuckle
For anyone interested:
Highway Code.
168 Being overtaken. If a driver is trying to overtake you, maintain a steady course and speed, slowing down if necessary to let the vehicle pass. Never obstruct drivers who wish to pass. Speeding up or driving unpredictably while someone is overtaking you is dangerous. Drop back to maintain a two-second gap if someone overtakes and pulls into the gap in front of you.
I daresay some will choose to ignore the following, but, some others might be interested.
The offence of dangerous driving under section 2 of the Road Traffic Act 1988 is committed when the defendant’s driving falls far below the standard expected of a competent and careful driver and it would be obvious that driving in that way would be dangerous – section 2A of the RTA 1988.
The Highway Code says that speeding up whilst being overtaken is dangerous.
All drivers should know the Highway Code.
Crossing the road is dangerous, but we all have to do it.
There are degrees of dangerous. Speeding up while being overtaken, approaching a blind bend is dangerous, but doing the same on a divided road rates lower than crossing the road.
Sometimes we just have to be childish.
Most trucks these days have sensors that slow us down if we get to close to car in front.
So why don’t they put sensors on the side that slow us down when someone is over taking problem solved
Our scania were reduced from 56 mph to 55 mph a while ago , some dafs are limited to 56 mph & others to 53 mph & economy mode on the mercs is 51 mph , override it / switch it off is 56 mph
Renaults , no idea as refuse to drive them , though I’m told there faster than anything else on fleet
