Stop Signs
Stop signs are traffic signs used to indicate that drivers must come to a complete halt before proceeding further. They are typically red and octagonal.
In Australia, the Australian Standard AS 1742.2 specifies the design and usage of stop signs.
The red colour and octagonal shape help drivers quickly recognise the sign and understand that they must stop at the marked line or intersection for safety reasons.
Once stopped, drivers can then proceed when it's safe to do so. These signs are commonly used at intersections and road junctions to control traffic flow and prevent accidents.
Prohibition Signs
Stop Signs are more exact than Prohibition Signs, where a particular activity is prohibited.
Prohibition Signs follow Australian Standard 1319 and have a red circle with a slash suggesting a particular activity is prohibited.
