The National Traffic Council (Contran) implemented new rules that bring significant changes for drivers and public transport operators. With the publication of resolutions 624 and 625, scheduled to take effect in November 2024, the norms aim primarily to reinforce safety on Brazilian urban roads. The regulation provides specific restrictions on the use of car sound systems, as well as weight limits for public transport vehicles and brings strict penalties for those who disregard these new criteria.
Resolution 624 from Contran brings important changes for drivers who use car sound systems in public areas. The new rule classifies the use of car sound systems that exceed permitted limits and disturb public order, whether by high volume or by bothering people on the streets, as a serious violation. Drivers who disregard this rule will be subject to a fine of R$ 195.23, in addition to receiving points on their National Driver’s License (CNH). It is worth noting that the legislation allows exceptions for sounds from mandatory equipment, such as horns and alarms, and for vehicles duly authorized to carry out sound advertising or events.
With this measure, Contran seeks to regulate the use of car sound systems in a way that balances the right to leisure with the tranquility of urban areas. Strict enforcement will allow authorities to quickly identify and punish drivers who abuse the volume of car sound systems, especially in heavily trafficked areas.
Weight Limits in Public Transport: What Changes with Resolution 625 from Contran?
Another novelty in Contran’s regulations is Resolution 625, which is aimed at the strict control of the Gross Vehicle Weight (GVW) of public transport vehicles. This rule aims to ensure that buses and other means of transport comply with the limits established in Resolution 210, in effect since 2006.

For the economist José Kobori, the USA gained a trump card to “blackmail” Brazil and undermine China’s influence by classifying the PCC and Comando Vermelho as terrorists, increasing the power to pressure companies, banks, and even Pix.

The labor shortage has changed its face in Brazil: companies hire 80% more, but workers stay only 6.8 months in the job, the service market becomes a “revolving door,” and businesses spend increasingly more to train teams that soon leave.

After selling a unit for R$ 115 million to pay off debts, a traditional factory in SC founded in 1932 has a new R$ 64.8 million plan denied by the court and retains about 690 workers in Joinville.
According to Contran, weight control is essential for passenger safety and for the preservation of urban roads, preventing excessive wear caused by vehicles that operate with loads beyond their capacity.
Impacts on Urban Traffic: Safety and Infrastructure
The implementation of resolutions 624 and 625 will bring noticeable changes to the urban environment. Reducing excessive use of car sound systems contributes to a more peaceful atmosphere, especially in residential and commercial areas. The weight control in public transport vehicles aims to minimize damage to road infrastructures, preventing the emergence of potholes and other recurring problems on the roads.
The Role of Contran and Enforcement in Implementing the New Norms
For the new guidelines to bring about the desired effects, enforcement will be crucial. Contran, in partnership with traffic authorities, will work to ensure that the resolutions are strictly adhered to, reinforcing a safer and more organized traffic system.
The collaboration of drivers and operators will be essential for making traffic in Brazilian cities more harmonious, avoiding conflicts and promoting the well-being of all.
With these measures, Contran reaffirms its commitment to a safer and more civilized traffic system, always seeking a balance between individual rights and collective well-being.

Outro detalhe é que eles possuem um sistema de som potente nos seus automóveis de luxo e tocam alto dentro de seus veículos só que estão na via a 180km/h 200 km/h e ninguém percebe !
Deveriam criar espaços para a prática dessa modalidade pois do mesmo jeito que há pessoas que não gostam tem pessoas que gostam , assim ficaria equilibrado para todos, só acho uma sacanagem os políticos regulamentarem regras que não cumprem por exemplo a fumo zero, todos são proibidos de fumar em ambientes fechados mas as excelências majestradas e etc… Fecham bares e restaurantes para desfrutar de seus cigarros e charutos cubanos
Eu só fico indignado, e que esses lixo quando e no tempo da política presisa do som automotivo quando passa a política fazem isso com o pessoal que tem som, lei lixo
