If you’ve ever hesitated at a school bus with its stop arm out, you’re not alone. The Connecticut school bus stop law for divided and undivided highways trips up many drivers, and the rules change based on the road type. Get it wrong, and you risk a fine or worse, a child’s safety.
Per Connecticut General Statutes § 14-279, the law is clear but often misunderstood. The difference between a divided and undivided highway is the key.
Quick Answer
The Connecticut school bus stop law for divided and undivided highways requires you to stop for a school bus with flashing red lights on undivided roads. On divided highways, only traffic moving in the same direction as the bus must stop. Fines for illegal passing start at $450.
The rule applies to all vehicles.
Connecticut’s School Bus Stop Law: The Simple Rule You Need to Know
The core rule is this: when a school bus stops and extends its stop arm with flashing red lights, you must stop if you’re on the same side of the road as the bus or on an undivided highway. The only exception is on a divided highway, where traffic moving in the opposite direction can proceed with caution.
This law exists to protect children boarding or exiting the bus. As of 2026, Connecticut enforces it strictly, with penalties that escalate for repeat offenses.
Divided vs. Undivided Highways: What’s the Difference?

A divided highway has a physical barrier or median separating traffic moving in opposite directions. This could be a concrete divider, grassy strip, or raised curb. If there’s anything solid between the lanes, it’s divided.
An undivided highway has no barrier. Traffic in both directions shares the same roadway, separated only by painted lines. This is the most common setup on rural and residential roads.

On an undivided highway, all traffic in both directions must stop when a school bus stops with its red lights flashing. This applies even if you’re on the opposite side of the road.
Here’s the breakdown:
- Undivided highway: Stop regardless of direction.
- Divided highway, same direction as bus: Stop.
- Divided highway, opposite direction: Proceed with caution.
When You Don’t Have to Stop on a Divided Highway
If you’re on a divided highway and the school bus is on the opposite side of the barrier, you don’t have to stop. The physical separation means children won’t be crossing your path to board or exit the bus.
However, always watch for children who might dart into the road unexpectedly. The law assumes the barrier provides safety, but vigilance is still required.
How to Tell If a Highway Is Divided or Undivided
Look for a physical barrier between lanes of opposite traffic. Concrete walls, grass medians, or even a row of flex posts count. If you see one, it’s divided.
If there’s only a painted line or nothing at all between directions, it’s undivided. This includes most two-lane roads where cars pass each other directly.
The Exact Fines and Penalties for Illegal Passing
First-time offenders face a $450 fine. Repeat violations can lead to higher fines and potential license suspension. These penalties apply whether you pass on the left or right of the bus.
Connecticut takes this seriously because illegal passing puts children at direct risk. The fines are non-negotiable and enforced by both local police and school bus cameras in some districts.
Common Mistakes Drivers Make (And How to Avoid Them)
Many drivers assume they can always pass a bus on the opposite side. That’s only true on divided highways. On undivided roads, this mistake can cost you.
Another error is not stopping far enough back. State law requires you to stop at least 10 feet from the bus. Creeping forward while children are boarding is both illegal and dangerous.
What School Bus Drivers and Parents Should Watch For
Bus drivers note license plates of violators and report them to police. Many buses now have exterior cameras that capture illegal passing on video.
Parents should remind children to look both ways before crossing, even when the bus lights are flashing. Not all drivers follow the law, so caution is still necessary.

If the highway is undivided, stop completely. If it’s divided and you’re on the opposite side of the barrier, you may proceed. When in doubt, stopping is always the safer choice.
Frequently Asked Questions

It depends. If the road is divided by a median or barrier, only traffic moving in the same direction as the bus must stop. If it’s undivided, all traffic must stop.

You must stop. The divided highway rule only allows opposite-direction traffic to proceed.
Can I get a ticket if a police officer doesn’t see me pass a bus?
Yes. Many school buses have cameras that record violations. The footage can be used to issue tickets.
Are there any exceptions to the stop rule?
No. All vehicles must stop for a school bus with flashing red lights on undivided roads or when traveling in the same direction on divided roads.
How far back should I stop from a school bus?
