Already the snow is flying fast and thick in many parts of the U.S. this week, particularly in Colorado, where a brutal blizzard shuttered schools and stranded vehicles.

Thus it’s high time to examine some of the ongoing winter preparatory activities across the transportation spectrum.

Then go check out the recent white paper penned by Michael Spence, senior VP of fleet services at Fleet Advantage, concerning how winter weather can impact commercial truck operations. For example:

  • Cooler ambient temperatures decrease engine efficiency and increase aerodynamic drag, with every 10 degree drop in Fahrenheit equating to a 2% increase in aerodynamic drag.

  • Tires lose pressure as temperatures drop and rolling resistance increases, thus reducing fuel economy.

  • Rain, snow and slush all increase tire rolling resistance as well, with cold water significantly cooling tires plus transmission and rear axle lubricants. This results in a 0.2 to 0.3 MPG loss as cited by the Society of Automotive Engineers (SAE) data.

  • Headwinds/crosswinds impact MPG as well, with every 10 mph worth of wind equating to a 13% drop in MPG.

  • Engine idle time increases in the winter months as drivers seek to stay warm, while poor driving conditions brought on by the cold and snow lead to decreased use of cruise control.
