Images of a supposed new traffic sign began to circulate on social media and caused confusion among drivers. The absence of symbols and the lack of official regulation raised questions about their validity and origin within the Brazilian system.
Images of a traffic sign that displays only a red circle with a white background and no symbol in the center have been circulating on social media.
The image generated confusion among drivers and even among industry professionals, who wonder if Brazil would have adopted a new signage, supposedly identified as R-100.
The content went viral after being published by a news site in Minas Gerais, attributing a novel function to the sign: to prohibit the circulation of all types of vehicles.

According to the publication, the new sign would have been identified with the code R-100, indicating a generic and comprehensive regulation.
However, this information is not accurate.
Sign R-100 Does Not Exist in the Brazilian Traffic System
The case is clarified by expert Ronaldo Cardoso, a traffic educator and creator of the LegTransito channel.
In a video published in response to the article, he claims that the sign does not officially exist and harshly criticizes the publication, classifying it as misinformation.
“This sign here, with a red circle and a white background, without a pictogram, has no validity at all. There is no R-100 in the Brazilian Traffic Signaling Manual,” Cardoso stated.
According to the expert, regulatory signs in Brazil follow a logical sequence, with codes from R-1 up to currently about R-45.
“Out of nowhere, an R-100 appeared? That does not exist. R is the letter that represents regulatory signs, but the numbering is progressive and has not reached that level,” he explained.
Lack of Pictogram Annuls the Validity of Signaling
In addition to the inconsistent number, the sign in question also violates basic signaling principles.
According to the technical manual of Contran (National Traffic Council), every prohibitory sign must contain a clear pictogram and, when necessary, a red diagonal stripe indicating the restriction.
In the case of the supposed R-100, there is no symbol or stripe, which, in practice, annuls any normative value.
“A prohibitory sign without a pictogram and without a stripe prohibits nothing. This is basic. There is no way to apply a penalty or consider an infraction based on a non-existent symbol,” emphasized Cardoso.
Article Does Not Mention Legal Basis or Infraction
The article that sparked the controversy was published by an intern in journalism, who, according to Cardoso, did not cite any official resolution, ordinance, or regulatory basis from Contran that justified the existence of this R-100.
“If the sign actually existed, the journalist should have indicated what infraction would be applied in case of disrespect. But none of this is mentioned because this sign is not regulated,” he reinforced.
In the original publication, it was also stated that the ignorance of the sign could affect “the well-being and safety of drivers.”
For Ronaldo Cardoso, the phrase is inappropriate and alarmist, as a signaling can only have legal effects after undergoing an official approval and dissemination process by the competent authorities.
“Brazilian journalism is going through a delicate moment when we see this type of content being published with such a lack of verification. This spreads like fake news on social media and confuses even traffic professionals,” he said.
Image Generates Misinformation About the Traffic Code
Cardoso also warned about the risk of propagating this type of image without technical basis.
According to him, driving school professionals even questioned the veracity of the sign, which shows how poorly crafted content can impact even specialized sectors.
Although the shape of the sign resembles regulatory signs — with red border and white background — its lack of pictogram and non-standard numbering prevents it from being interpreted as official.
The sign mentioned in the video would actually be just an image without technical or legal basis.
In Brazil, the sign that prohibits the circulation of motor vehicles is the R-10, which has a clear and nationally recognized symbol.
Any new signage must be approved by Contran and published through specific resolutions, which is not the case with the supposed R-100.
With the repercussion of Ronaldo Cardoso’s video, the expectation is that the topic will serve as a warning for press vehicles and social media users about the importance of fact-checking information related to traffic signaling.
