Trucks hitting 70 downhil

[T5R+]

Recently had a spell on the M1 (in the car) and whilst following trucks downhill, couple of times noticed that they were nudging 70 (GPS not speedo verified). Happened three or 4 times over the week.

Is this still normal?

Admittedly on on 2 occasions they were machinery movers complete with hiabs but on others conventional tractor+trailer.

Not unusual but the drivers run the risk of incurring fines from DVSA if discovered on the digital tacho as they record overspeeding if it continues for more than a given time , the UK limit is 60 mph but most tachographs will show overspeeds if 91-92 kph is exceeded . There are ways of deceiving the units but are a bit of a rigmarole including changing tyres/wheels .

Why show overspeed it they are within the speed limit? 60mph = 96.6kph.

Because we are in the EU and subject to the directive that states you must have limiter, set speed not to exceed 90 KPH on lorries...

Ah. Euro logic.

stick it in neutral if you have a load and it'll shoot down the motorway.

i do class 2 recovery and do the manchester to leeds run quite often and there's a few downhill segments where its easy to do 70/80mph with this method.

as others have said it does record overspeeding on your tacho

Don't even need a load in most things.

DVSA tend to ignore overspeeding at roadside checks. I certainly don't know anyone who has fallen foul.

And you don’t ‘stick it in neutral’ either.

What do you do, then?

Allow it to jump into neutral

Heheh.
That HAS happened to me a few times on that road in particular.

The foolish post that I was replying to has been deleted, but you just leave your foot flat on the accelerator and let gravity do its thing. When a vehicle weighs 30-40 tonnes then it will easily and quickly reach 60mph(target), or more if you allow it to.

The DVSA aren't unduly worried about over-speeds providing that they don't continue for too long. I think that they have a bogey time which exceeds what you should be able to achieve down the longest incline that we have, but this is only word of mouth, although from a VOSA officer.

With Stoneridge tachos you can exceed the limited speed for 60 seconds without recording an over-speed, so most instances will not be recorded and the driver wont have any speed-related infringements. Many don't care, as over-speeds aren't on the DVSA's radar, providing that the limited is correctly set and hasn't been tampered with.

That´s good info, mate. Or..is it? Is it bad info? Is it still good info if it leads us law abiding citizens astray? even though it´s info, and ALL info is good, innit?
I´m doing my own head in.
