BATON ROUGE — High diesel prices continue to squeeze food truck and catering businesses in Louisiana. Some owners said they may have to pass those costs on to customers if there is no resolution soon.

Khris Loyd has spent more than two decades serving lemonade from a food truck traveling across South Louisiana. What started as a hobby to make extra money has grown into seven lemonade stands and a truck known as The Lemonade Bus.

His truck, which travels to events, festivals and football games, runs on diesel. Loyd said higher fuel prices have raised the cost of running the business and shipping costs for materials.

"Fuel prices have impacted our bus, our work vehicles as well," said Khris Loyd. "Even our lids and straws that we use have to be trucked in, most of that coming on diesel, and with it being more than $2 what it was, it obviously impacts our bottom line. We've been able to hold the line right now on our costs."

As a result, Loyd said the bottom line is crunched.

"Unfortunately, we would have to move those costs over to customers. It would also mean that possibly some of the further events that we do, our customers will incur a higher surcharge for us to get there," said Loyd.

According to GasBuddy, industries across the country have felt the impact of rising fuel prices for months. On Monday, Pres. Donald Trump signed an executive order aimed at easing restrictions on tax-free, red-dyed diesel.

GasBuddy petroleum analyst Patrick De Haan said the order will not add any new diesel to the market. In a social media post, De Haan said rising prices are tied to a shortage of supply, not taxes.

According to AAA, the average price of diesel in Louisiana is about $5.84 a gallon. That was down slightly from late September, but analysts do not expect a major price drop anytime soon, as severe global oil supply constraints remain with the continuing war with Iran.
