Frequently Asked Questions
How many road signs are on the Ontario G1 test?
The Ontario G1 knowledge test has 20 road signs questions out of 40 total. You must answer at least 16 of the 20 correctly (80%) to pass the signs section. Failing road signs means failing the whole test — even if you ace the rules section.
What do yellow diamond signs mean?
Yellow diamond-shaped signs are warning signs. They alert you to a hazard ahead — a curve, an intersection, a railway crossing, deer, falling rock, or a narrowing road. You are not required to stop, but you should slow down and be prepared for the condition described.
What do orange signs mean in Ontario?
Orange signs mark construction or temporary traffic control zones. All HTA fines — especially speeding — are doubled in designated construction zones when workers are present. Always obey reduced speed limits in construction zones.
What is the difference between No Stopping, No Standing, and No Parking?
No Stopping means your vehicle cannot stop at all — not even for a second. No Standing means you can stop only to load or unload passengers (no waiting, no goods). No Parking means you can stop briefly to load/unload passengers or merchandise but cannot leave the vehicle unattended.
What shape is a regulatory sign in Ontario?
Most regulatory signs use a white rectangle with black text or symbols. Some use red circles with diagonal bars to show a prohibited action. Exceptions include the Stop sign (red octagon) and the Yield sign (white and red inverted triangle), which are technically regulatory signs with unique shapes.
