The national law firm of Baron and Budd is investigating possible overtime pay violations by tank truck transportation companies after a recent $14 million settlement in a California case brought attention to the issue.

Even though there are some exemptions, when a driver does not cross state lines they should be paid overtime under the Fair Labor Standards Act (FLSA). However, companies typically neglect to pay the overtime, usually in an attempt to save money, according to the law firm.

In the California case, tank truck transportation provider KAG West LLC was accused of not paying workers overtime, forcing drivers to work off the clock, and not allowing meal or rest breaks. KAG agreed to pay a $14 million settlement to employees included in the case.

“Many tank truck drivers may not realize it, but you are due overtime pay if you don’t cross state lines as part of your job,” said Allen Vaught, head of Baron and Budd’s FLSA litigation section.

The firm is concentrating its current investigation in Texas.

“This case has helped to bring the issue to the forefront and proves that these violations are happening,” said Vaught.
