When Must a Commercial Truck Driver Take a Mandatory Post-Accident Drug & Alcohol Test in Texas? (49 CFR § 382.303)
Direct Answer Under Texas Law
Under 49 C.F.R. § 382.303, a motor carrier MUST administer a post-accident alcohol test (within 2 to 8 hours) and controlled-substances drug test (within 32 hours) to a commercial CDL driver whenever a crash on a public road involves: (1) a human fatality (testing is ALWAYS mandatory regardless of whether the trucker got a ticket!), OR (2) the truck driver receives a moving traffic citation AND either (a) anyone is transported from the scene for immediate medical treatment, or (b) any vehicle is towed from the scene due to disabling damage!
Critical Texas Procedural Trap to Watch Out For
If the motor carrier fails to test the driver within the 8-hour alcohol / 32-hour drug window required by § 382.303(d), the carrier is legally required to prepare and maintain a written record stating the exact reasons why the test was not promptly administered!
Recommended Action Plan for Texas Claimants
Demand the post-crash DOT Custody and Control Form (CCF), breath-alcohol strip, FMCSA Drug & Alcohol Clearinghouse query history, and any § 382.303(d) written excuse log.
Detailed Texas Statutory & Case Law Breakdown
Under 49 C.F.R. § 382.303(a)–(d) (8-Hour Alcohol / 32-Hour Controlled Substances Window) and controlling Texas appellate precedent in FMCSA Clearinghouse Query Mandate (49 C.F.R. § 382.701), 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).
