Read school bus railroad construction and emergency vehicle factors

By Jacob Alford

School buses, railroad crossings, work zones and emergency vehicles each have particular triggers and exceptions. Identify the lights, signals, roadway configuration and vehicle involved. The current move-over law contains more detail than a slogan about slowing down. Use the linked statute and facts, not the abbreviated label alone.

Questions this group helps answer:

• When must traffic stop for a school bus?
• What creates the duty to stop at a railroad crossing?
• What warning or barricade applied in the construction area?
• How is yielding to an approaching emergency vehicle different from moving over for a stopped one?
• What is the slow-down rule when the posted limit is under 25 mph?

18. Disregard warning sign at construction

Meaning in the report: A driver disregarded construction-zone warnings in a way that contributed to the crash.

What needs explaining: The relevant warning and the driver’s response must be identified. Was the warning installed, visible, applicable to this lane and encountered before the hazard?

Limits and qualifications: The cited barricade statute is more specific than a general statement that every construction warning creates the same offense.

Related law and scope: Subsection (a) forbids disobeying warning signs or driving around a barricade. Subsection (e)(3) defines warning sign, including a flagger, and extends to construction, repair or dangerous conditions. Subsection (b) exempts police-directed travel and persons whose duties require going beyond/around the barricade.

Sources: TxDOT definition, page 137; Transportation §472.022.

Further care: Workers’ presence affects the enhanced penalty in (d)(1); it is not an element of every underlying (a) violation. The manual’s construction label is narrower than the statute’s dangerous-condition coverage.

30. Failed to stop for school bus

Meaning in the report: The driver failed to stop or remain stopped for a school bus receiving or discharging children with the required signals operating.

What needs explaining: Verify the bus activity and visual signals, including when movement could lawfully resume. Were the bus signals active, were children boarding or leaving, and were the vehicles on the same roadway?

Limits and qualifications: Divided-roadway and controlled-access exceptions must be checked before calling it a violation.

Related law and scope: Subsection (a) applies from either direction when a school bus is stopped to receive/discharge a student and operates required signals. Remain stopped until the bus resumes, the driver signals proceed, or the visual signal ceases. Subsection (b) gives separate-roadway and qualifying controlled-access loading-zone exceptions; (f) defines separate roadways.

Sources: TxDOT definition, page 138; Transportation §545.066.

Further care: A center left-turn lane alone does not create separate roadways. Verify the bus’s activity and signal, direction, physical separation and whether a statutory release condition had occurred.

31. Failed to stop for train

Meaning in the report: Disregarding a crossing gate, flagger, signal or a plainly visible, hazardously close train contributed to the crash.

What needs explaining: Identify the trigger that required a stop and the position of the train. What warnings were operating, how visible was the train, and where did the vehicle stop or proceed?

Limits and qualifications: A railroad collision does not replace proof of the relevant statutory stopping duty.

Related law and scope: Read (a)–(e): signal/gate/flagger/train or other on-track equipment triggers; required stopping distance; remaining stopped until permitted and safe; crossbuck-only yielding/stopping; and a ban on going around/under/through a gate while closed, closing or opening.

Sources: TxDOT definition, page 138; Transportation §545.251.

Further care: The current statute includes other on-track equipment, not just trains, and expressly covers a gate being opened. Manual language is incomplete as a full elements list.

32. Failed to yield right of way emergency vehicle

Meaning in the report: A vehicle failed to yield to a legally authorized emergency vehicle responding to an actual emergency in compliance with the applicable statutes, and that contributed to the crash.

What needs explaining: The emergency vehicle’s status, response and statutory compliance matter. What lights and audible signals were operating, what was the response, and where could the other driver safely move?

Limits and qualifications: Distinguish yielding to an approaching emergency vehicle from the stopped-vehicle move-over rule in code 78.

Related law and scope: Current (a) covers qualifying authorized emergency vehicles, medical-examiner vehicles, justices-of-the-peace vehicles and police vehicles lawfully using only audible or visual signals. Under (a-1), on immediate approach yield, pull right clear of an intersection, stop and remain until passed unless police direct otherwise; (b) preserves the approaching vehicle operator’s due-care duty.

Sources: TxDOT definition, page 138; Transportation §545.156; Transportation §541.201(1),(13-a) (related provision); Transportation §547.305 (related provision); Transportation §547.702 (related provision); Transportation §547.751 (related provision); Transportation §547.752 (related provision).

Further care: Manual actual-emergency shorthand does not state the complete current category and signal tests. Sections 547.751 and 547.752 also display amendments effective in 2027. Use the version in force on the crash date; those later amendments are not current law as of this reference’s November 4, 2026 source check.

78. Failed to slow or move over for vehicles displaying emergency lights

Meaning in the report: Failure to comply with the protected-vehicle move-over or slow-down rule contributed.

What needs explaining: Identify a vehicle covered by the statute, its required signals, road configuration and the driver’s response. What protected vehicle was present, what lights were displayed, how many lanes were available and what was the speed limit?

Limits and qualifications: The manual’s 20-mph-below shorthand is incomplete for posted limits under 25 mph and does not capture every condition in current law.

Related law and scope: Subsection (a) now lists 8 covered categories. The operative duty is (b): unless police direct otherwise, vacate the closest lane on a highway with at least 2 lanes traveling in the vehicle’s direction, OR slow to a speed at or below the posted limit minus 20 mph when the limit is 25 mph or above, or no more than 5 mph when it is below 25 mph.

Sources: TxDOT definition, page 143; Transportation §545.157(a); Transportation §545.157(b),(e) (related provision); Transportation §547.305(d),(e-4) (related provision); Transportation §547.702 (related provision).

Further care: The manual’s summary omits the under-25-mph/5-mph rule, the lane-count condition, the police-direction exception and the speed ceiling. Subsection (a) identifies covered vehicles; subsection (b) supplies those duties and qualifications. Covered categories are qualifying emergency, tow, TxDOT/contract-maintenance/construction, utility-service, municipal-waste/recycling, toll-project, animal-removal and local parking-citation vehicles. Each has its own activity/stationary/light conditions. The waste/recycling category (a)(5) has no express light condition, so the factor title is not a complete statement of statutory scope. Subsection (b) provides alternatives; it does not require both moving over and reducing speed by 20 mph in every case.
