A School Bus Stop Arm Violation occurs when a vehicle passes a stopped school bus in violation of Section 545.066 of the Texas Transportation Code, as amended, which is a civil offense under Dallas City Code Chapter 28, Article XX, Section 28-224. A vehicle must come to a complete stop behind the stop arm of an unloading school bus. Unless there is a raised median separating opposing traffic (turn lanes do not fall into this category), traffic traveling opposite the school bus must come to a complete stop as well, and all traffic must wait until the stop arm is retracted to continue. Violations are captured by cameras that record traffic activity passing the school bus in both directions. Violations are reviewed and verified by a peace officer and citations are then mailed to the vehicle owners.
