Truckers and ordinary consumers will certainly benefit from lower gas prices.
Unless your trucking business is hauling, water, material, oil, pipe, valves etc for the oil industry.
Analyst predicts impact of cheap oil: less cargo, lower rates

Moving less cargo is not going to help the trucking industry.
Ask the thousands truckers in the oil patch about that, and the many thousands of consumers from Virginia to Idaho who draw a good oil-related paycheck.
If you are saving money at the pump, I say good on you. That's how the market works.
But there are a great many 'ordinary' people who will be squeezed, and maybe wiped out, if things in the patch get real bad and stay that way.
Ordinary consumers yes....but truckers need loads to deliver.
Thousands of truckers will no longer have a job also.
