MINNEAPOLIMEDIA NEWS | Minnesota Closes School Bus Safety Loophole, Expands Driver Stopping Requirements

ST. PAUL, MN (April 2026) A new Minnesota law is now in effect requiring drivers to stop for school buses as soon as red warning lights begin flashing, eliminating a legal ambiguity that previously delayed when motorists were required to stop.

The change was enacted through Senate File 3623 and signed into law by Tim Walz in late March 2026. The law took effect immediately upon signature and amends Minnesota Statute 169.444, which governs school bus safety.

Key Change in State Law

Under the updated statute, drivers must stop at least 20 feet from a school bus whenever its red lights are flashing and remain stopped until the lights are turned off and the stop arm is fully retracted.

The revision removes prior language that tied the stopping requirement to the extension of the bus’s stop arm. State officials said that wording had created uncertainty about whether drivers were required to stop if the arm had not fully deployed.

A 2025 ruling by the Minnesota Court of Appeals highlighted that ambiguity, prompting legislative action to clarify the law. The updated statute establishes flashing red lights as the sole legal trigger requiring vehicles to stop.

Clarified Signal System

The law also reinforces the sequence of school bus warning signals:

• Flashing amber lights: Indicate the bus is preparing to stop. Drivers are required to slow down and prepare to stop.
• Flashing red lights: Require all traffic in both directions to stop at least 20 feet away, regardless of the stop arm’s position.
• End of stop: Drivers may proceed only after the red lights are turned off and the stop arm is fully retracted.

Penalties for Violations

Violating Minnesota’s school bus stopping law remains a misdemeanor offense with a minimum fine of $500. More serious violations, including passing a bus on the right side where children enter and exit or passing when a child is outside the bus, can be charged as a gross misdemeanor.

Enforcement and Safety Data

The Minnesota State Patrol and the Minnesota Office of Traffic Safety supported the legislative change, citing ongoing enforcement challenges and safety risks.

According to state data, more than 2,000 citations were issued statewide for stop-arm violations between 2024 and 2025. Officials also note that many violations go unreported due to the difficulty of observing incidents in real time.

To address enforcement gaps, school districts across Minnesota have increasingly adopted stop-arm camera systems. The cameras capture video and license plate images of vehicles that pass illegally, allowing citations to be issued after the incident.

Safety Rationale

Public safety officials said the change is intended to eliminate hesitation during the critical moments when students are boarding or exiting buses. Because red lights activate before the stop arm is fully extended, children may already be approaching or entering the roadway when drivers encounter the bus.

By making the flashing red lights the clear and immediate signal to stop, lawmakers aimed to create a uniform, easily understood standard for motorists and reduce the risk of crashes involving students.

State agencies continue to emphasize public awareness as the law takes effect, urging drivers to treat flashing red lights on a school bus as an immediate stop requirement in all cases.
