Regulatory signs carry a legal penalty. Advisory signs do not. For example, a black and white speed limit sign is regulatory, and you can be fined for violating it. A yellow ramp speed sign is advisory and simply a safety device.
A one way road sign means that traffic is only permitted to travel in the direction of the white arrow.
"Regulation sign" Reference: It is regulating something. Failure to obey these signs can result in a traffic citation.
The correct answer is NO. A stop sign is considered a Regulatory Sign. Regulatory signs are typically the colors black, white, and/or red. Regulatory signs regulate traffic and tell a driver about a law. Examples include speed limits, yield signs, one way streets, do not enter signs, no turning, no parking, and (yes) stop signs. A warning sign, on the other hand, is typically diamond-shaped and the color yellow, orange or pink. They warn you of possible changes in the use or condition of the roadway ahead. A stop sign is not warning you to stop. It is TELLING you to stop because that is the law.
In the US, STOP signs are Octagonal (8 sided), with a bright red background and white letters saying STOP.
In the UK 'Ahead only' is indicated by lane markings and will either be an arrow painted on the road or you may see a sign that depicts all lanes, displaying arrows indicating where the traffic in each lane may travel.Our one-way signs (used to indicate that traffic can only travel in one direction) look similar to american 'Ahead only' signs, as they are white arrows on a blue back ground.Keep left/right arrows are also white arrows on blue backgrounds, but they point slightly towards the ground. These are used on traffic islands to make sure traffic passes on thecorrect side.
On U.S. highways, green signs with white text are generally for navigational information: Upcoming exits and junctions, freeway entrance and exit signs, and street signs.
