Danger Warning Signs

The convention backed rules for danger warning signs are simple and very uniform in design, with little variation. Danger warning signs are either a diamond or an equilateral triangle shape, with a white or yellow background, and a red or black border. You will see danger warning signs as you approach a narrowing road, a train crossing without barrier, or an upcoming pedestrian zone. When approaching an area marked with a danger warning, proceed with caution.

Examples of triangular shaped danger warning signs:

Approaching road will become narrower with little to no breakdown lane, sometimes leading to bridge or causeway.

Approaching intersection with train tracks will have no barrier or gate to prevent traffic movement.

Approaching a high foot-traffic area, including schools, shopping districts and landmarks. Use extreme caution.

Examples of diamond shaped danger warning signs:

Approaching turn may be hazardous without first reducing speed.

Road ahead will be hazardous with winding roads and a reduced ability to see oncoming traffic.

Approaching overpass will have a maximum height allowance, which is advised on the sign in either feet or meters.
