Deer Crossing Sign
The deer crossing sign warns that deer and other wildlife frequently cross the road in this area. Drivers must reduce speed and be prepared for animals entering the road suddenly.
Last updated: April 4, 2026
Deer crossing signs are placed at locations where deer are known to regularly cross roads, such as near forest edges, agricultural land boundaries, and wildlife corridors. In Ontario, deer-vehicle collisions are most common at dawn and dusk from October through December during the deer rut and hunting season. Deer often travel in groups, so if one crosses, others likely follow.

What does the Deer Crossing Sign mean?
Deer crossing signs are placed at locations where deer are known to regularly cross roads, such as near forest edges, agricultural land boundaries, and wildlife corridors. In Ontario, deer-vehicle collisions are most common at dawn and dusk from October through December during the deer rut and hunting season. Deer often travel in groups, so if one crosses, others likely follow.
What to do when you see it
Reduce speed when you see this sign, especially at dawn, dusk, and night when deer are most active. Use high beams where possible to spot animals at the road edge. If a deer appears on the road, brake firmly and honk your horn: do not swerve sharply, as this risks losing control of the vehicle. If a collision is unavoidable, hit the deer rather than swerving into oncoming traffic or off the road.
Where you'll see it in Ontario
Deer crossing signs appear on rural highways, county roads, and provincial roads running through or near wooded areas in Ontario. They are especially common on roads through the Canadian Shield, the Oak Ridges Moraine, and agricultural regions of Southern Ontario.
G1 test relevance
While not a primary G1 test topic, animal crossing signs fall under general knowledge of warning signs. Candidates should know that warning signs are yellow diamonds and that the correct response is always to reduce speed and increase caution.
Common mistakes drivers make
Swerving sharply to avoid an animal is more dangerous than a direct collision in many cases. Maintaining control of the vehicle and braking in a straight line is safer. Another mistake is not reducing speed after seeing the sign because no deer are immediately visible.
