Updated July 2026. Road signs make up half of Ontario’s G1 written test — 20 of the 40 questions — and they’re the section most people underestimate. It’s not enough to recognize a stop sign; the exam tests shape and colour recognition for signs you may have never consciously noticed. This page focuses specifically on the signs section, with a free practice quiz below.
How Ontario Road Signs Are Organized
The Ontario Driver’s Handbook groups signs by shape and colour, and the exam tests exactly this system — recognizing a sign’s category from its shape alone, even before reading the text:
- Red octagon — Stop signs (the only octagonal sign in Canada, by design, so it’s recognizable even when obscured)
- Yellow diamond — Warning signs (curves ahead, pedestrian crossings, merging traffic, slippery road)
- White rectangle, black text — Regulatory signs (speed limits, no parking, one way)
- Yellow-green pentagon — School zone signs
- Orange diamond — Construction and temporary condition signs
- Blue rectangle — Services (hospital, gas, rest area)
- Green rectangle — Directional/guide signs (highway exits, distances)
Sign Categories Tested on the G1
Regulatory Signs
These tell you what you must or must not do: speed limits, no-entry, one-way, no U-turn, keep right, and lane-use signs. Missing these on the exam is common because several look visually similar (compare “No Parking” vs. “No Stopping” — different rules, similar sign).
Warning Signs
Yellow diamonds warning of what’s ahead: curves, hills, merging traffic, pedestrian crossings, deer/wildlife crossings, slippery roads, and traffic signals ahead. The exam often tests whether you know the appropriate response to a warning sign, not just its meaning.
Information and Guide Signs
Green and blue signs showing directions, distances, and services. Fewer exam questions come from this category, but they still appear.
Construction Signs
Orange signs indicating temporary hazards — lane closures, flag persons, detours, reduced speed zones. Ontario tests these because construction-zone violations carry doubled fines.

Study Tips for the Signs Section
- Learn by shape first, text second. The real exam sometimes shows a sign image with no text — you need to recognize the shape/colour category instantly.
- Drive around your neighbourhood and name every sign you see. Passive recognition from years of driving (or being driven) doesn’t always translate to active recall under exam conditions.
- Pay special attention to signs that look alike. “No Parking,” “No Stopping,” and “No Standing” are three different rules with three different (similarly styled) signs — a common exam trap.
- Review the handbook’s full sign chart at least once close to your test date, even for signs you’re confident about.
Frequently Asked Questions
How many road sign questions are on the G1 test?
20 of the 40 total questions. You need at least 16 of those 20 correct to pass the signs portion — passing the overall test requires passing both the signs and rules sections separately.
Are the signs on the test the same as what I see on the road?
Yes — Ontario uses standardized signs designed by the Ministry of Transportation, and the exam draws directly from the current Driver’s Handbook.
Do I need to know sign colours if I’m colour-blind?
Sign shape is designed to be a backup identifier for exactly this reason — a stop sign is the only octagon on Ontario roads regardless of colour perception. Mention any accommodation needs to DriveTest staff before your test.
What happens if I fail only the signs section?
You must retake the entire written test, not just the section you failed. There’s a $16 fee for each retake attempt, after waiting at least one day.
