Oklahoma now requires every food truck operating in the state — including out-of-state trucks attending local events — to meet strict fire-safety rules. Under the updated Oklahoma Fire Marshal Directive 2024-2 and House Bill 3995, any mobile food preparation vehicle that produces smoke or grease-laden vapors must be equipped with an automatic hood suppression system or, through 2025, approved portable fire extinguishers that are professionally inspected each year.
What the Law Says
As of June 1 2024, HB 3995 (Title 74 § 325.20) allows food-truck operators to temporarily rely on properly maintained Class K fire extinguishers instead of an installed suppression hood. Each extinguisher must be inspected annually by a licensed contractor, with documentation kept on board. This temporary allowance expires November 1, 2025, when all trucks will be required to have permanent fire-suppression systems that comply with the adopted Oklahoma Fire Code.
Who's Affected
This mandate covers all food trucks serving in Oklahoma, even those registered in other states or visiting for fairs and festivals. Cities such as Durant and Norman have already adopted the state requirement, enforcing inspection decals and compliance certificates for event permits.
Why It Matters
Grease fires can ignite in seconds. Oklahoma’s new rules ensure consistent safety standards for operators, event organizers, and the public — reducing the risk of catastrophic fires that can quickly spread in mobile kitchens.
What to Do Now
Schedule your annual inspection with a licensed fire-protection company.
Verify that you have a Class K extinguisher (for oil/fat cooking) and a current inspection tag.
Begin planning installation of a hood suppression system before the November 2025 deadline.
