Why don't trucks go 55 for fuel efficiency?

Most truckers go 65 or even 75+. I know you would be able to do less runs if you limited your speed to 55, but wouldn't the fuel efficiency be worth it? Why don't more people do that?

 

Seriously? Sammy said it best. I CAN'T DRIVE..... 55 .

 

Electronic Logbooks. Accidents have gone up as truckers are rushing around trying to beat the clock.

 

Unlimited trucks tend to go the speed the driver is capable and happy driving, limited trucks go their max speed as often as they possibly can.

Far fewer actual owners of the trucks that care about fuel cost drive the trucks, also while fuel is expensive and one of the primary costs in trucking, it makes little sense to chase dimes to lose dollars

 

You could do the same amount of runs and run the same amount of miles at 55 or 75. It ain't how fast you go, its how much ground you cover. Can a driver limit his stops? I've seen truckers pass me multiple time in a run foong 75(I'm governed at 65). Not all trucks get the best fuel efficiency at 55. I think the sweet spot is somewhere between 62-65. You burn less fuel, and if you're under a heavy load, high speeds can be tragic over time to your truck.

 

Those who try to beat the clock don't know how to work in my opinion. I personally dont see what difference it makes whether the log book is electronic or paper. 600 miles is still 10 hrs a lot of days.

 

I'll do 57 or 58 if I have all day to do a couple hundred miles. But usually more like 62.

As far as other people, one big factor might be people willing to pay for an extra half hour of TV time. Plus most drivers don't pay for their own fuel, so they don't care about mpg, aside from the few who chase the mpg bonuses.

 

Those other trucks might be geared different.

 

Me i don't do that because i wanna finish my day and or have better stuff to do than bite my nails worrying about squeezing a few more tenths.

 

Not every truck or operation is as efficient as the same speed as others.
