Pennsylvania school-bus stops: ten feet and the roadway exception

When a Pennsylvania school bus prepares to load or unload, look at its signals, your approach and the roadway separation. Counting lanes alone will not tell you whether you may pass. A child may cross where your view is blocked by the bus.

Red signals and stop arms mean a complete stop

Under 75 Pa.C.S. §3345, a driver meeting or overtaking a stopped school bus with flashing red signals and activated side stop arms must stop at least ten feet before reaching the bus, subject to the separate-roadway exception below. That distance applies when approaching from the front or rear.

PennDOT’s school-bus safety page also identifies drivers traveling alongside the bus and drivers approaching an intersection where it is stopped. Do not assume that a green traffic light, a turning movement or a lane next to the bus gives permission to proceed past the stop.

Amber lights have a different meaning: proceed cautiously and be ready to stop. Ease off early and assess the bus rather than accelerating to get past before the lights change.

Use roadway separation, not the number of lanes

Situation	Driver’s response
Behind the bus on its roadway	Stop for its red signals and stop arms
Approaching from the opposite direction on an undivided road	Stop, even if the road has several lanes
Approaching an intersection where the bus is stopped	Stop at the intersection as the law requires
Bus is on a different, physically separated roadway	The separate-roadway exception can apply to opposing traffic

PennDOT describes separating features such as a grassy median, guide rail or concrete median barrier. A painted centerline or a center turn lane alone does not create that physical separation. The statutory exception is for a bus on a different roadway, not merely a different lane.

For example, two lanes each way with only painted markings still require opposing drivers to stop. Add a genuine dividing median that separates the opposite roadway, and the opposing-roadway exception may apply. Drivers behind the bus on its own roadway still stop.

Wait for both the signals and the children

Remain stopped until the red lights have stopped flashing, the stop arm is withdrawn and all children have reached safety. Section 3345 specifically prohibits resuming motion before children who got off the bus have reached a place of safety. A child looking toward a driveway may still be about to cross your lane.

Do not substitute another motorist’s decision for your own check. If the car ahead starts moving, verify the bus signals and look for children before following. Likewise, a bus that has merely paused in traffic is different from a bus displaying its school-bus stopping signals; observe the actual conditions.

Rehearse a calm approach

On a route with frequent school-bus stops, leave enough space to see the bus and stop smoothly. Watch both sides of the road, including between parked cars. Stop short of the required minimum rather than edging forward to improve your view. Keep your attention on the children and bus while waiting.

If you are unsure whether a median genuinely creates a different roadway, reduce speed early and assess the layout; do not make a last-second pass based on the road’s width. Learn the divided-road distinction before your next trip, using PennDOT’s linked illustrations.
