It's not very safe when a 65.1 mph truck is trying to pass a 65.0 mph truck hogging up both lanes on the interstate.
Trucks need a "Push to Pass" system like the Formula cars have![]()

when you drive 75mph comparing to 55mph is takes lot more distance to stop truck in emergency here is very often that you have traffic jam on highway on once .....so you have to stop truck in very short distance
also driving slower result in lower possibilities for blowing tire or similar
so here we have big discussions about to limit speed to 49.7mph .....
most companies drive this speed now
but problem will be if they will limit trucks to 49.7 this will increase fuel consumption because truck will be always in limit so this will be reducing throttle and than when speed drops , returning to 80kmh-by cruise control so this will cause worst economy than today -

Something interesting; this week my truck wasn't busy do I took a friends scania r 620 6*4 to holland, it was a tandem or double drive unit, I ran with another of the companies trucks, an r620 6*2 with a lift/steer axle,both had auto gearboxes, we both had the same trailers and loads of machine parts, almost exactly the same weight too and same conditions, the 6*4 I was driving was 0.8 mpg's worse on fuel than the 6*2, I guess what I witnessed was frictional losses in action due to the extra machinery of the second drive axle, I am now definately sold on dice's route of micro polishing,

do you know axle ratio and tires on both of them
because we can see some long legged 620 single drive
but very hard to drive fast 6x4
truck
this also can be lot of difference -

I see too many of the 75+ mph Supertruckers racing from one truckstop to the next with the same trucks passing you 2 and 3 times in a 200 mile leg of most trips. I will trade 2 or 3 hours for each dedicated run to save in fuel the equivalent of around $100 per hour......$100 per hour makes for a nice paycheck and besides I don't need to stop near as much because I am not wore out mentally from your own words "truck dodging 4 wheelers", in and out of slower traffic, slamming on brakes because of slower traffic, working with traffic that would be close to my speed and tailgatting all those slower vehicles to get them out of the way that is all very tiring mentally....been there done that.
I have tried it both ways and most that make fun of going slower have never tried it.tphammer, 98989, The Challenger and 3 others Thank this. -
I understand the company drivers who like to drive hard and fast, I was like that too but when it's your truck and your paying for your own fuel, tyres and maintenance you will slow down and drive at a steady pace,scottied67 Thanks this.
