Company executives have been watching these numbers also. The friends I know in the positions of adjusting rates say it is a slow process because tariffs are posted. These can and will be adjusted, it is a slow process and the contractors like yourself pay the price before adjustments can be initiated. With prices constantly fluctuating they have a formula to follow. In the past years I had a friend who owned a large fleet of 150 trucks and he could not adjust rates quick enough because of contracts with shippers. He ended up closing his doors in less than 90 days. My advice to you would be to reduce idling, slow your speed a few miles per hour,make sure tire pressures are all where you want them, clean fuel and air filters. You kinda getting where I'm heading with this? Conserve fuel with every opportunity you can! Change your driving style to make the most out of every gallon. And if you ever thought about a generator before, well this may push your decision to operate a 3 or 4 cylinder engine that is in the 20 H.P. range versus that 350 horse air conditioner you been running. Do your part and operate safely and efficiently! This is going to be the difference between making profit and breaking even. Good luck and let us know how you make out?
