Don't know what this has to do with buses ... but did you notice the sign in the truckstop that read "Diesel 47 cents?"  Ah, the good ol days.

The speedo on the bus says between 35 and 40 mph and I pass every one like they are chained to the guardrail.  The p.o. said the speedo was reading about half speed and the phone call from the wife behind me in the truck confirmed that.  I guess I really should get that fixed.  Grin Grin

The reason I asked the question is because I see some responses to questions stating to just slow down to 55 MPH to save on fuel.  On two lane roads that mostly have 55 or 60 MPH limits that seems perfectly reasonable.  You'll probably have folks latched to your rear bumper, but you just have to learn to ignore them.

I can see driving a bus at 55 MPH inside of the state of California because isn't the speed limit for large vehicles 55 MPH anyhow?  I can't see going that slow on interstates in Nebraska, Wyoming, Utah, and other states with 75 MPH limits for all vehicles.  I mostly go 65 MPH with the bus for fuel economy and safety.  I advocated slowing down to 60 MPH in 2008 the last time fuel was really high, but the rest of my group didn't want to be on the road for an extra three hours.

I drive in the right lane and try to find a truck that's doing around 60 and just follow him around 200 yards back.  If a truck wants to pass me, I slow down to let him past faster.  I guess I am going around 60 - 62 most of the time.  that's on flat road.  I try to pick up speed going down a hill into a climb, and I climb hills as fast as she will go, whatever that is.  I often find my self going too fast on flat roads and have to back off to get back to my preferred speed.  I don't drive 55 on purpose very often, on major highways.

In Illinois the speed limit is 55 for semi trucks motorhomes and buses if I remember correctly --- that is even on the interstates

Illinois eliminated the truck speed limit recently.  Limit is now 65 MPH for all vehicles.  BK said the 55 MPH limit specifically did not apply to buses.  The signs said trucks, RVs, and trailers from what I recall.  I'm sure BK had checked into the speed limit issue for buses.

If you really want to drive 55 just post the back of the bus with the sticker that says "this vehicle does not travel above 55mph"......Up here in Quebec I have noticed everyone has slowed down as fuel got pricier.  In fact when fuel takes a leap everyone slows down.....I drive 110 kmh (68 mph)never any more to keep fuel down.....if I drove 100 kmh (62 mph) I would save more....if I drove 55 mph (89 kmh) I would fall asleep, but I could use the fuel savings to pay the higher premiums after I crashed.  I have tried to drive 55 for a long time but it is soooo hard to do.

I generally try to get behind a Schneider or Werner truck.  Those guys travel at a good safe speed and I think are among the safest out there.

In 2008 I made a monthly trip of 90 miles round trip in my car.  The speed limit is 70 MPH on the interstate.  I was only driving 65 MPH because I was towing a small trailer.  When I made the trip in May 2008 I was passing quite a few cars even at 65 MPH.  Lots of people going slow due to fuel costs.  In June 2008 I was going the same 65 MPH but rarely passed anyone and hardly any cars passed me.  By July 2008 I was being passed like I was standing still while driving 65 MPH on the road.

The interesting thing is fuel prices didn't peak until after my trip in July 2008.  I think people either adjusted their budgets to pay for the gas or they got sick of driving slow and put the gas on their credit card or something.

Last summer I helped my friend drive his new (to him) Crown tandem back home.   Because the tach wasn't accurate, and because we didn't know how the engine had been set, we kept at exactly 55 MPH down 99 from Sacramento to Bakersfield and over Tehachapi to his house near Hesperia.   Boy, was that boring!   Interestingly, there were quite a lot of trucks also doing that speed, so we just convoyed along with them.   That was certainly the most relaxing drive I've ever done, having no worries about speeding tickets from the ever-vigilant CHP revenue agents.

When we got back to his house we calculated his bus had got over 10 MPG at that speed, and that includes going over Tehachapi.   That's not bad for a thirty-year-old skoolie weighing 25,000 empty!   (In comparison, his Hemi Ram pickup that I was driving barely got 25 MPG at that speed, and he said that's the best it's ever got all the time he's owned it.)   The Crown has a 270 HP turbo 6-71 with a Spicer 10-speed.   He's recently replaced its tach, so now at about 2100 indicated RPM it does almost 70 MPH.   If instead it had the overdrive RTO it would be good for at least 80 MPH!   I've heard of some Crowns getting 12 MPG, so I can believe that if they have the RTO.

I personally think anyone driving slowed then 10mph below the posted speed is endangering themselves and others.  If circumstances are beyond your control and driving slower is necessary safety dictates you stay in the right lane....

That pretty much goes without saying, that if you are driving slower than traffic, (no matter the speed limit or how fast the traffic is going), you should be in the right lane.
