Mate all modern trucks have speed limiters...... Granted that they can be disabled however those guys are on timelines from one point to another and if they get there too quick, every one knows they broke the speed limit. Speeding trucks are EXTREMELY rare these days.
haha, that's one of the biggest lies I've seen, you get trucks doing between 110 and 140 all the time out my way, it somewhat rare to get one doing 100 in a 100 zone, which doesn't make speeding all that rare.
And most truckies seem to 'lose' all the time they gain from speeding by catching a few minutes extra sleep from what I see.
Also, I believe that you shouldn't be on the road if in a 80/90/100 zone you feel you have to overtake the L/Red P/Green P plater (respectivly
) in front of you when they are pushing the speeds they can legally travel at anyway.
