What does the School Bus Stop Ahead Sign mean?
This sign warns drivers that a school bus regularly stops in this area to pick up or drop off children. When a school bus displays its overhead red alternating lights and extends its stop arm, all vehicles on the same road must stop and remain stopped until the lights stop flashing and the bus resumes movement. On divided roads with a raised median, only vehicles on the same side as the bus must stop.
What to do when you see it
Be prepared to stop as you approach this sign. Watch for children near the road or waiting at bus stops. When a school bus ahead or approaching from the opposite direction activates its red lights, stop at least 20 metres away from the bus. Do not proceed until the lights stop flashing and the bus moves.
Where you'll see it in Ontario
School bus stop ahead signs are posted near regular school bus stops in residential neighbourhoods, on rural roads, and on roads approaching schools. They indicate a consistent, known stop location.
G1 test relevance
School bus laws are heavily tested on the G1 exam. Key rules: stop at least 20 metres from the bus, stop on both sides of an undivided road, and do not proceed until the bus resumes movement. On a divided road with a raised median, vehicles on the opposite side of the median do not have to stop.
Common mistakes drivers make
Passing a school bus with flashing red lights is one of the most dangerous and heavily penalized driving offences in Ontario. It carries significant fines and demerit points. Another common error is failing to stop on divided roads when the school bus is across the median.
