Digest
HB 3726 expands Texas’s “move over or slow down” law to cover additional roadside vehicles. Current law applies when a driver approaches certain stationary vehicles, including emergency vehicles, tow trucks, Texas Department of Transportation vehicles, highway maintenance or construction vehicles, utility service vehicles, solid waste or recycling vehicles, and certain toll project vehicles. The committee substitute adds a vehicle stopped on the shoulder of a highway or adjacent to a highway if the vehicle is using compliant hazard lamps or is marked by other warning devices, such as traffic cones, flares, or retroreflective devices.

By adding this category, the bill would require drivers approaching those vehicles to comply with the existing move-over-or-slow-down requirements: changing lanes away from the stopped vehicle when safe and possible, or reducing speed as required by current law. The bill does not create a new standalone offense; rather, it expands the set of vehicles covered by the existing offense for passing certain stationary vehicles on a highway.

The Committee Substitute also amends Transportation Code Section 547.305(e-4) to clarify that the newly added category of stopped roadside vehicles is not among the vehicles authorized to be equipped with flashing blue lights.

The originally filed HB 3726 and the Committee Substitute for HB 3726 both amend Transportation Code Section 545.157(a), the statute governing the offense of passing certain vehicles on a highway. Both versions add a new category of covered vehicles: a vehicle stopped on the shoulder of the highway or adjacent to the highway. In the filed version, that new category applies only when the stopped vehicle is using hazard lamps that comply with Transportation Code Section 547.331.

The Committee Substitute broadens that new category. Instead of covering only a stopped vehicle using compliant hazard lamps, it also covers a stopped vehicle that is “demarcated by other warning devices,” including traffic cones, flares, or retroreflective devices. This means the substitute would apply even when the stopped vehicle is not using hazard lamps, so long as warning devices mark the vehicle.

The Committee Substitute also adds a second statutory change not found in the originally filed bill. It amends Transportation Code Section 547.305(e-4) to clarify that only the existing vehicle categories in Section 545.157(a)(1) through (6) may be equipped with flashing blue lights. By excluding the newly added category in Subdivision (7), the substitute makes clear that ordinary stopped roadside vehicles covered by the expanded move-over-or-slow-down law are not newly authorized to use flashing blue lights.

The practical difference is that the Committee Substitute is broader in its roadside-safety coverage but more explicit about limiting blue-light authorization.

Fiscal Notes

According to the Legislative Budget Board (LBB), HB 3726 is not expected to have a significant fiscal implication to the State. The fiscal note states that the bill would modify rules related to passing certain vehicles on a highway, and LBB assumes any costs associated with implementing or enforcing the bill could be absorbed using existing resources.

For local governments, the LBB likewise anticipates no significant fiscal implications. The fiscal note does not identify any required local spending, new administrative structure, grant program, or revenue loss associated with the bill.

The key fiscal implication is therefore limited: the bill may create some enforcement or administrative workload for agencies such as the Department of Public Safety or the Department of Transportation, but LBB does not project those costs to require additional appropriations. The fiscal note does not describe any costs as recurring or one-time, and it does not characterize the fiscal impact as indeterminate.

Vote Recommendation Notes

Texas Policy Research recommends that lawmakers vote NO  on HB 3726. Although the bill responds to a legitimate roadside-safety concern, it does so by expanding the scope of an existing traffic offense to cover ordinary vehicles stopped on or adjacent to a highway when using hazard lamps or marked by warning devices such as traffic cones, flares, or retroreflective devices. The bill analysis states that the proposal would extend the existing move-over-or-slow-down requirements to these newly covered vehicles and would subject violations to the existing offense structure, including misdemeanor liability, Class A misdemeanor treatment if bodily injury results, and state jail felony treatment for certain subsequent offenses.

The principal concern is overcriminalization. Current law applies to identifiable categories of official, emergency, utility, highway, service, waste, and toll project vehicles. HB 3726 would expand that framework to ordinary stopped vehicles, which may present widely varying circumstances in real time. A disabled vehicle may be partially visible, poorly positioned, intermittently using hazard lamps, or marked with warning devices in a way that is not immediately clear to approaching drivers. Because the bill relies on roadside conditions that may be ambiguous after the fact, it increases the number of situations in which ordinary drivers could face criminal penalties based on a highly fact-dependent judgment.

The bill also raises enforcement-discretion concerns. A driver approaching a stopped vehicle may not always have a safe opportunity to change lanes, especially in heavy traffic, poor weather, construction areas, rural highways, or near entrance and exit ramps. While existing law contains a move-over-or-slow-down structure, the bill does not add additional guardrails tailored to the broader and less predictable category of ordinary stopped vehicles. Without clearer statutory limits, the bill could invite uneven enforcement and after-the-fact disputes over whether a driver had sufficient notice, whether warning devices were adequately visible, or whether a lane change was reasonably possible.

The limited-government concern is not primarily fiscal or administrative. The bill analysis states that the bill does not expressly grant additional rulemaking authority, and the LBB fiscal note anticipates no significant fiscal implications to the state or local governments. The concern is instead the expansion of state coercive authority. Even when no new agency or appropriation is created, expanding a criminally enforceable traffic duty still increases the reach of government power over ordinary conduct.

The bill’s safety objective is understandable, particularly given the bill analysis’s concern that the current law does not cover drivers who pull over after an accident or car trouble. However, criminal law should be narrow, clear, and limited to circumstances where the duty imposed on citizens is reasonably knowable and enforceable with minimal discretion. As drafted, the committee substitute broadens the move-over-or-slow-down offense beyond clearly identifiable official roadside vehicles without sufficient protections for drivers facing unclear or unsafe roadway conditions.

Free Enterprise
neutral
The bill does not impose a direct regulatory burden on businesses, create subsidies, restrict market entry, or alter licensing rules. Any effect on commercial drivers or business fleets would arise from generally applicable traffic enforcement rather than a targeted business regulation.
Property Rights
neutral
The bill does not affect ownership, use, possession, transfer, or control of private property. It does not authorize takings, impose land-use restrictions, or condition property use on new compliance obligations.
Personal Responsibility
neutral
The bill encourages drivers to exercise caution around disabled or stopped roadside vehicles, which aligns with personal responsibility in a general safety sense. However, it shifts more responsibility into a criminal enforcement framework rather than relying on driver judgment, education, civil remedies, or clearer notice-based standards. A narrower bill with explicit safe-harbor protections would better respect responsible driver discretion.
Limited Government
negative
The bill does not create a new agency, program, fund, or rulemaking authority, and the bill analysis states that it does not grant additional rulemaking authority. However, limited government is not only about fiscal or bureaucratic growth. By expanding the scope of a criminally enforceable traffic duty to a broader and less clearly defined class of roadside vehicles, the bill expands state coercive authority and enforcement discretion. That is the primary limited-government concern.
Individual Liberty
negative
The bill expands the reach of an existing traffic offense to cover ordinary vehicles stopped on or adjacent to a highway when using hazard lamps or marked by warning devices. That creates additional criminal exposure for drivers in roadside situations that may be unclear, fast-moving, or difficult to assess safely. The liberty concern is heightened because violations may carry misdemeanor liability and enhanced penalties when bodily injury results.
