% grade

Q: What does the (&#37 percentage mean?

A: It refers to how many feet you'll descend per 100 foot of roadway. On a 5% grade, you'll descend 5 feet per 100 feet of roadway.

A grade has a percentage and a length. For example, let's take a 6% grade that is 10 miles long. This means that for every 100 foot of roadway, you are going to drop 6 feet. For each 1% of grade you'd descend 52.8 feet, since 5,280 feet equals one mile.

Are these posted by the administrators as a test to see if we will control ourselves and not insult the poster?

 

If you drive a truck and it is electronically controlled it logs speed and RPM and coasting. I am sure there is a rule about coasting, and if you drive for a company when they down load the specs, and it shows coasting you will be coasting down the road.
Also should anything happen, while or after you have been coasting I am sure you will be talking to the boys with the Tuxedo Pants

 

You never take a truck out of gear going down a grade. You put it in the gear to get keep the speed that is posted at the top of the grade. You'll learn the particulars of mountain driving when you start learning how to drive.

The percent refers to as mentioned above. The distance refers to how many miles you will be dealing with that percentage of a grade.

 

YOU'VE been wondering about??? Almost 7 years ago,on my VERY 1st run,I had a 2 drop load,1st drop some where in Co.,2nd in N.M....I forget the cities I dropped in,but I DO remember I had to drop into N.M. from Co on U.S. 550...... That stretch had a song made about it from the 1970's by a C.W. McCall,I'M sure someone reading this in my age group would remember that...Anyway,since then,I have gone over many many Western Mountain ranges,but,I too,always wondered what formula was used to determine mountain grades..I don't think that was a dumb-as# question,bur,if it was,Sign me, the 7yr OTR dumb-as# guy..

 

I would put a "BRAKE" on being retarded right now if you want to drive a Big Truck..Hey,do what you want,I could really care less,just sayin..

 

That song would be "Wolf Creek Pass".....

"Wolf Creek Pass (el. 10,857 ft.) is a high mountain pass on the Continental Divide, in the San Juan Mountains of Colorado. It is the route through which U.S. Highway 160 passes from the San Luis Valley into southwest Colorado on its way to New Mexico and Arizona. The pass is notable as inspiration of a C. W. McCall song. Though not as formidable as the song made it seem, the pass is significantly steep on either side (7 to 8% in most places), and can be dangerous in winter."
