Texas Transportation Code section 542.404 doubles the minimum and maximum fines for most traffic offenses committed in a construction or maintenance work zone when workers are present and the citation says so. In a crash claim, the rule shows how seriously Texas treats work zone driving. Owsley Law Firm handles construction zone crashes and charges no fee unless we win.
Construction is constant on Houston freeways, from I-45 to the 610 Loop. Narrowed lanes, sudden shifts, and stopped traffic make work zones dangerous for drivers and workers. Texas raises the penalties for traffic offenses in these zones when workers are present.
The fine itself does not compensate anyone. What matters in a claim is the conduct the statute targets: speeding, distraction, and unsafe lane changes where the road demands extra care. This page explains the rule and how work zone crashes are handled.
When are traffic fines doubled in a Texas work zone?
When the offense occurs in a construction or maintenance work zone while workers are present, and the written notice to appear states that workers were present.
Work zones also change how a crash is investigated. The traffic control plan for the project shows where signs, barrels, and lane closures were supposed to be. Comparing that plan to photos of the scene can reveal whether the contractor set up the zone as required or left drivers without adequate warning of a lane shift or stopped traffic.
Both the minimum and maximum fines double. For speeding under a prima facie limit, the doubled fine applies only if the work zone is marked with a sign showing the maximum lawful speed. Some offenses, including seat belt violations, are excluded.

Who can be responsible for a work zone crash?
The at-fault driver, and sometimes the contractor or government entity responsible for traffic control in the zone.
A contractor that left poor signage, missing barrels, or an unmarked lane drop may share fault. When a government entity is involved, the Texas Tort Claims Act applies, with notice deadlines and damages caps.
- The driver who caused the crash
- A construction contractor responsible for traffic control
- TxDOT or a city, subject to the Tort Claims Act
- An employer if the driver was working
How does a work zone affect fault?
Drivers must adjust to the conditions. Speeding or distraction in a work zone weighs heavily against a driver under Chapter 33.
The reasonable and prudent speed rule in section 545.351 requires lower speeds for special hazards, which includes construction. A driver who kept highway speed through a lane shift was likely not driving reasonably.
What if a road worker was injured?
A worker can usually pursue a claim against the driver who hit them, in addition to workers’ compensation benefits.
Workers’ compensation covers on-the-job injuries for workers whose employer carries it. A negligent driver who is not the employer can still be responsible for the worker’s full damages.

Are work zone speed limits enforceable without signs?
Doubled fines for exceeding a prima facie speed limit apply only if the work zone is marked with a sign showing the maximum lawful speed.
Section 542.404(c) ties the doubled fine for prima facie speed violations to posted speed signs. For an injury claim, posted limits and warning signs are still important evidence of what a reasonable driver should have done.
Even without a posted reduction, section 545.351 requires drivers to slow for special hazards, which includes lane shifts, barriers, and workers near the road.
What should you do after a work zone crash?
Photograph the signs, barrels, lane markings, and the work area, and note the contractor’s name on equipment or signs.
Work zone setups change daily. Photos taken at the scene may be the only record of how the zone looked at the time of the crash.
How it is proven after a crash
- Photos of signs, barrels, and lane markings
- The contractor’s name and project number
- Traffic control plans for the project
- Video and event data recorder speed
- The crash report noting workers present
Mistakes that cost people money
- Not photographing the work zone layout
- Missing Tort Claims Act notice deadlines
- Assuming the contractor cannot be responsible
- Waiting to see a doctor
Frequently asked questions
Do work zone fines double if no workers are present?
No. Section 542.404 requires workers to be present and the citation to say so.
Can I sue a construction company for a work zone crash?
Yes, if its traffic control was negligent and contributed to the crash.
What if TxDOT was responsible for the work zone?
Claims against the state follow the Tort Claims Act, including six-month notice under section 101.101 and damages caps under section 101.023.
Does the work zone law apply to seat belt tickets?
No. Seat belt offenses under section 545.413 are excluded.
How long do I have to file?
Generally two years from the crash under section 16.003, with earlier notice deadlines for government claims.
