OK HB3300

Motor carriers are prohibited from connecting to, hauling, or towing any trailer unless it is covered by active liability insurance meeting minimum state or federal financial responsibility requirements

Before connecting to a trailer, motor carriers must verify insurance through a certificate of insurance from the owner/lessor, an electronic verification system or database, or written/electronic certification confirming active coverage

Documentation of insurance verification must be retained for at least 2 years and made available to the Corporation Commission or Department of Public Safety upon request

If a motor carrier tows an uninsured trailer and an accident, spill, detachment, or other incident occurs, a rebuttable presumption of negligence arises, making the carrier liable for cleanup costs, property damage, personal injury or death, and administrative penalties

A safe harbor exempts carriers from the negligence presumption if they relied in good faith on verification documents reasonably believed valid and retained records, even if the trailer was later found uninsured—effective November 1, 2026
