Gas and diesel prices in Florida jumped sharply in a matter of days, bad news for drivers and worse for trucking companies already short of drivers.

• Florida pump prices jumped overnight, and oil has kept climbing toward $100 a barrel since.
• Federal regulators shut down or cited hundreds of truck driving schools nationwide, including three in Central Florida, over English proficiency rules and weak training standards.
• That crackdown hits an industry already short about 82,000 drivers, so fewer new drivers are coming in just as fuel costs rise.
• Drivers in hard-hit Florida counties are skipping trips and cutting back wherever they can.

Outlook: Higher fuel costs plus a thinner pipeline of new drivers point to more expensive trucking, which usually shows up later in the price of everything that moves by road.
