Lorries in the UK can't get to 70mph. They have speed limiters.
I didn't comment on whether it's a good idea, I'm just pointing out a fact. The speed limit for HGVs on a Mway is 60, they have limiters to 56. Is this a good idea? Well, if the alternative is lorries routinely breaking the speed limit, speed limiters are probably the least bad alterative. If you think it's a bad idea, what would you rather and why?So that’s a good idea then, as one creeps past another ?
Bear in mind that if an HGV driver/mechanic did disable the limiter and the police pulled him over, the first thing they would do is look at the tacho. If that shows routine speeding or any signs of tampering, the next step is an engineer's inspection to see if the limiter is still in place. No? The vehicle operator and driver can look forward to their day in court then. Illegal vehicle mods I'm sure are very well received by the local beak.
There's a way to avoid problems with HGVs on Mways and dual carriageways without breaking any speed limits. Set your speed around 65, engage cruise control if you have it, and sit back. You'll be able to overtake all the HGVs you want without them getting in your way or you lingering too long in Lane 2 or Lane 3 , anybody wanting to go faster can overtake you whenever you like, and you'll get great fuel economy. I did this this morning on the M1 past Wakefield, the journey passed without incident.
