what a sign mean that has a red circle with rock in it and a red line through it
A no parking sign is usually a P with a red circle around it and a line through it. That sign simply means you can't park your vehicle there.
A black square with a red line is often used as a symbol for "No" or "Prohibited." It is commonly seen in warning signs to indicate that a particular action or behavior is not allowed.
You come to a complete stop at the limit line or before entering the crosswalk/intersection of that specific red stop sign.
no on the red square
The no smoking logo is simply a picture of a cigarette in a red circle with a red line through it. Sometimes just the words 'No Smoking' are used on a sign instead of the logo.
it means that gays should have equal rights.
A red circle with a white horizontal line means no entry. this means the road only goes in 1 dirrecdtion.
You are possibly thinking of the AXA logo
A red circle with a blue horizontal stripe through it.
stopping used just like a stop sign
The stops sign is red rather than another color purely through custom. It is also fair to say that red is very noticeable whereas yellow might not be so clear.
