Warning signs alert you that there may be dangers or changed road conditions ahead. The signs are usually diamond-shaped with pictures, diagrams, symbols or words in black on a yellow background. These are some of the most common warning signs.
Diamond-shaped signs signify warnings.
Warning. Warning signs are diamond shaped and are yellow or orange with black letters or symbols. They warn of dangerous or unusual conditions ahead, such as a curve, turn, dip or side road.
Warning signs warn of a hazard or hazardous condition that is not likely to be life-threatening. Its symbolic shape is a black triangle. A black pictograph usually appears inside the triangle to indicate the specific hazard. The sign background is yellow with any text in black.
WARNING SIGNS normally are yellow and diamond-shaped, with black letters or symbols.
Warning safety signs (Yellow)
They can indicate a general hazard/danger and are sometimes known as hazard/caution signs. These health and safety signs need to be yellow/amber and are usually characterised by a black symbol on a yellow background.
Orange = Warning. These orange or predominantly orange signs and tags generally have black lettering or symbols. Orange often is used for potentially dangerous parts of machinery or equipment that may cut, crush, shock, or otherwise injure a person.
There are four colours associated with health and safety signs: red, yellow, blue and green. Red indicates prohibition, yellow is for hazards, blue is for mandatory action and green is for emergency exits or first aid.
On the roads, drivers don't have much time to react to danger. When they see a triangular sign, they automatically know to be more cautious long before they can see what is actually on the sign.
Triangle signs – usually white with a red border – are here to let you know that you're approaching a hazard or a place to stop. They will usually point upwards and feature an image of the hazard: merging traffic, a junction on a bend, a slippery road or a zebra crossing are all examples of common warning road signs.
Signs are divided into three basic categories: Regulatory, Warning, and Guide signs.
The shape of each safety sign communicates a distinct message to the users. Safety signs are grouped into 3 categories of regulatory, information, and warning. Each category is ascertained by the shape of the sign.
Intrinsic features: round shape. black pictogram on white background, red edging and diagonal red line (the red part to take up at least 35% of the area of the sign)
Circles are orders or positive information. Triangles are warnings and finally, rectangles are information. When we look at lights they help control the flow of traffic.
Mandatory signs are blue, prohibition and fire safety signs are red, warning signs are yellow, and first aid and emergency exit signs are green. The psychology behind these signs can symbolise safety, instruction or danger, depending on the colour.
Yellow – warns of physical hazards and means caution. A striped or checkered pattern of yellow and black may be used to help attract attention. Blue – denotes caution and its use is restricted to marking out-of-service equipment which should not be used.
These color are based on very firm research about psychology of signal: Red for error, danger, wrong. Green for success, safe, right. Yellow for alert, caution, warning.
Yellow and orange often indicates a warning that might need attention.
The Color Red Conveys Danger and Warning
Its ability to instantly grab people's attention is the reason why it's often used to warn people of impending danger. Think: stop signs, sirens, fire engines, and red traffic lights.
The use of red on signs is limited to stop, yield, and prohibition signs. White: A white background indicates a regulatory sign. Yellow: Yellow conveys a general caution message. Green: Green shows permitted traffic movements or directional guidance.
The red-and-white YIELD and DO NOT ENTER signs prohibit access or movement. WARNING SIGNS Yellow warning signs alert you to hazards or changes in conditions ahead. Changes in road layout, proximity to a school zone, or some special situation are examples of warning signs.
The Importance of Colors and Shapes in Traffic and Road Signs Standard colors and forms of sign boards can be used to streamline traffic flow and communicate effectively with the traffic environment. Colors may reveal as much about a sign's meaning as the complete sign.
Shapes matter
Not only does your brain interpret sign colors, but it also recognizes certain shapes as meaning certain things. Road sign shapes and colors together can a single mean meaning. Virtually every driver or pedestrian would immediately understand a red octagon as a stop sign even with no writing on it.
