Does knight have a "no idyl" policy?

Not true. Your truck speed is 65 if you keep your idle% under either 10 or 12%. Can't remember which. Truck speed drops to 63 if you exceed their standard.

 

ive heard this as well, but no idea if is true or not

 

So if you drive 10 hrs, you can idle one full hour in Texas, at 87 degrees at night parked in south Dallas.

 

You can idle all you want and drive a 63 mph truck. In the cool months, it's not hard at all to keep idle % under 10% and drive a 65mph truck. Don't need to idle for heat. In the warm months just expect to run 63. I got a 62mph truck here at Crete and still average 11k+ per month.

 

Lets see, I can be cool when its hot, and warm when its cold and go 63mph? Or I can freeze when its cold, or roast when its hot and do 65mph? Most truck speeds are around 60mph?
What the h***, throw caution to the wind. Lets get idle crazy and only drive 63. As long as it goes at least 60, why care. Too fast you may get caught speeding, here comes those tickets and points.

 

Its a fuel economy thing. You are rewarded for not idleing by having a slightly faster truck. Remember, times you are stuck in traffic, red lights, trains, ect increase your idle times also.
Here at USA TRUCK our trucks always run at 63 which is fast enough for me. Our idle policy is 5% if you have an APU and 99.8% of our trucks do. The penalty for going over 5% is a call from fuel economy.
