Ontario G1 Road Signs Practice: Complete Visual Guide 2026

Road signs are one of the two sections on the Ontario G1 knowledge test. You need at least 16 out of 20 questions correct to pass the signs portion. Many candidates fail specifically because of signs — so mastering them gives you a huge advantage.

The Sign Colour System

Ontario road signs use a strict colour code:

Red — Prohibitions and stops. Stop signs, yield signs, wrong-way signs, no-entry, no-U-turn, no-parking.

Yellow — Warnings. School zones, construction, railway crossings, pedestrian crossings, curve warnings.

Orange — Construction and temporary conditions. Used exclusively in construction zones.

Blue — Information and services. Motorist services (gas, food, lodging), hospital signs.

Green — Direction and guidance. Highway markers, exit signs, distance signs.

White — Regulatory. Speed limits, lane control, one-way signs.

Brown — Parks and recreation. Provincial parks, heritage sites, tourist attractions.

Regulatory Signs You Must Know

Stop Sign — Eight-sided, red with white lettering. Full stop required. One of the few signs where shape alone identifies it even if colour is faded.

Yield Sign — Downward triangle, red and white. Slow down and give right-of-way.

Speed Limit Signs — White rectangular, black numerals. Speed shown is maximum for ideal conditions.

No U-Turn, No Left Turn, No Right Turn — Red circle with diagonal red bar over the prohibited movement.

Warning Signs to Memorize

Warning signs are yellow diamonds. Key ones on the G1 test:

- Pedestrian crossover (walking figure) - School zone (two children figures) - Railway crossing (X with "RAILWAY" text, or round advance warning sign) - Curve ahead (bent arrow) - Slippery road (car with wavy lines) - Traffic signal ahead (traffic light symbol)

Passing Strategy

The sign questions on the G1 test often show you just the shape and colour — no text. Practice identifying signs by visual appearance alone, not by reading the words. TRY2PASS includes over 200 road sign questions for Ontario, covering every sign in the MTO handbook.
