BR-101: The Most Dangerous Highway In The Country
According to a study by the National Transport Confederation (CNT), Santa Catarina has five of the ten most dangerous road segments in the country.
BR-101, which runs through the state from north to south, stands out negatively.
The segment between kilometers 110 and 120 recorded 235 accidents and nine deaths, while the segment between kilometers 190 and 200 accounted for 249 accidents and three deaths during the analyzed period.
Other Critical Segments In Santa Catarina
In addition to BR-101, other federal highways in Santa Catarina feature critical segments.
BR-470 has four segments with a high incidence of accidents, the most concerning being between kilometers 50 and 60, with an 88% probability of severe occurrences during Carnival 2025.
BR-280 has three critical segments, with the segment between kilometers 50 and 60 having a 75% chance of serious accidents.
Causes Of Accidents And Preventive Measures
Various factors contribute to the high accident rate on Santa Catarina’s highways.
Among the main causes are the recklessness of drivers, such as improper passing and speeding, along with adverse road conditions, including inadequate signage and lack of maintenance.
To mitigate these issues, it is essential to implement preventive measures, such as:
- Strict Enforcement: Increased enforcement operations to curb traffic violations and ensure compliance with the laws.
- Traffic Education: Educational campaigns aimed at raising drivers’ awareness of safe and responsible behaviors.
- Infrastructure Improvements: Investments in maintenance and expansion of highways, ensuring better traffic conditions and safety.
Economic And Social Impact
The high accident rates affect not only the victims and their families but also have significant repercussions on the economy and society.
The costs associated with medical care, material losses, and reduced productivity are substantial.
Furthermore, the sense of insecurity on the roads can negatively impact tourism and freight transport, vital sectors for the economy of Santa Catarina.
The Worst Highways In Brazil
The CNT survey also highlighted other highways with critical conditions.
Among the ten worst in the country are:
PE-545, from Exu to Ouricuri (PE): Features about 70 kilometers with poor paving and signage conditions.
PE-096, from Palmares to Barreiros (PE): With approximately 48 kilometers, this highway faces significant structural problems.
PB-400, from Cajazeiras to Conceição (PB): Segment with high accident rates due to lack of adequate maintenance.
RN-118, from Macau to Itajá (RN): Known for its poor conditions, negatively impacting local traffic.
PE-177, from Quipapá to Garanhuns (PE): Highway with critical segments that need urgent repairs.

Perspectives For The Future
The situation of Brazilian highways requires continuous attention and strategic investments.
In addition to emergency measures to reduce accident rates, long-term planning that includes regular maintenance, efficient enforcement, and driver awareness is essential.
With the implementation of effective public policies and community engagement, it is possible to transform this scenario and reduce the negative impacts of dangerous highways.
