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. |
