What Is the Difference Between Federal Interstate (11/14 Hr) and Texas Intrastate (12/15 Hr) Truck Driver Hours of Service?
Direct Answer Under Texas Law
Texas enforces two different sets of Hours-of-Service (HOS) fatigue limits depending on whether the load crosses state lines (or is part of interstate commerce): (1) Federal Interstate Rules (49 C.F.R. § 395.3): max 11 hours driving within a 14-hour on-duty window after 10 consecutive hours off duty (max 70 hours in 8 days); (2) Texas Intrastate Rules (37 Tex. Admin. Code § 4.11, for trucks operating exclusively inside Texas on non-interstate freight): max 12 hours driving within a 15-hour on-duty window after only 8 consecutive hours off duty (max 70 hours in 7 consecutive days)!
Critical Texas Procedural Trap to Watch Out For
Many trucks driving strictly inside Texas (e.g., from the Port of Houston to Dallas) are STILL governed by the stricter 11-hour FEDERAL rule if the cargo inside the trailer originated outside Texas or is bound for another state ('stream of interstate commerce')!
Recommended Action Plan for Texas Claimants
Trace the cargo's Bill of Lading origin and final destination to prove the trip was part of continuous interstate commerce, holding the driver to the stricter 11-hour federal driving limit and 10-hour rest requirement.
Detailed Texas Statutory & Case Law Breakdown
Under 49 C.F.R. § 395.3 (Interstate 11/14/70 Rule) vs. 37 Tex. Admin. Code § 4.11 (Texas Intrastate 12/15/70 Rule) and controlling Texas appellate precedent in Rayner v. Dillon, 501 S.W.3d 143 (Tex. App.—Texarkana 2016), Texas trial and appellate courts apply strict statutory rules to this exact issue. Unlike generic multi-state legal summaries, Texas tort procedure under the Civil Practice and Remedies Code (CPRC), Insurance Code, Transportation Code, and Labor Code enforces specific statutory formulas—including the 51% proportionate responsibility bar (CPRC § 33.001), paid-or-incurred medical expense admissibility (CPRC § 41.0105 / Haygood), and mandatory statutory lien caps (Prop. Code Ch. 55 & Ins. Code Ch. 140).
