After Two Months of Detailed Studies, State Begins Installation of New Radar and Speed Reducers. The Measure Covers Important Highways Aiming to Reduce Accidents and Save Lives. The Equipment Starts Operation in February, but Already Sparks Debates About Safety and Enforcement. Fines in Sight?
Drivers traveling on the highways of Vale do Caí and Serra Gaúcha should pay attention to a new development that promises to directly impact safety and wallets: new radar and speed reducers are being installed at 15 strategic points in the region.
The decision, which seeks to reduce accident rates, was made after two months of technical studies and analysis of detailed data.
Where Will the Equipment Be Installed?
According to the concessionaire Caminhos da Serra Gaúcha (CSG), the speed controllers will be distributed along the ERS-122, RSC-453, ERS-240, RSC-287, and BR-470 highways.

In total, 25 new devices, including radar and speed reducers, will be operational, with a planned start of operations in February 2025, although the exact date has yet to be confirmed.
The ERS-122, one of the busiest highways in the region, will receive the largest number of devices, with 10 monitored points.
The other devices will be distributed along the other mentioned highways, covering sections considered critical.
Studies and Justifications
As explained by the chairman of CSG, Ricardo Peres, the decision to install the controllers was made after a thorough study that identified locations with the highest incidence of accidents.
“During the study, in addition to our technical assessment, we consulted security institutions and local communities to define the most urgent sections, ensuring that the measure is effective in preventing collisions and fatalities,” he emphasized.
Initially, the contract provided for the installation of controllers at only 10 points.
However, after tests and in-depth analyses, it was decided to expand the project by adding five more points to cover critical areas, increasing safety for drivers and pedestrians.
Which Sections Will Be Monitored?
Check below the sections that will receive the new devices, including the speed limits that must be observed:
ERS-240
- Two speed reducers at kilometer 7 (both directions), with a limit of 60 km/h.
RSC-287
- Two speed reducers at kilometer 1 (both directions), with a limit of 40 km/h.
BR-470
- Two radars at kilometer 226.2 (both directions), with a limit of 60 km/h.
RSC-453
- Two speed reducers at kilometer 107 (both directions), with a limit of 50 km/h.
- Two radars at kilometer 117 (both directions), with a limit of 60 km/h.
ERS-122
- Two speed reducers at kilometer 10.8 (both directions), with a limit of 60 km/h.
- One radar at kilometer 46.1 (direction Caxias do Sul), with a limit of 50 km/h.
- One radar at kilometer 46.7 (direction capital), with a limit of 50 km/h.
- Two radars at kilometer 50.5 (both directions), with a limit of 60 km/h.
- One radar at kilometer 55.6 (direction Serra), with a limit of 60 km/h.
- Two radars at kilometer 72.1 (both directions), with a limit of 60 km/h.
- Two radars at kilometer 85.5 (both directions), with a limit of 60 km/h.
- Two speed reducers at kilometer 92 (both directions), with a limit of 40 km/h.
- One radar at kilometer 107.9 (direction Vacaria), with a limit of 60 km/h.
- One radar at kilometer 136.2 (direction Vacaria), with a limit of 60 km/h.
Fines and Responsibility
It is important to emphasize that, according to CSG, the responsibility for issuing fines for speeding lies with the Departamento Autônomo de Estradas de Rodagem (Daer), and the collected amounts will be directed to the government of Rio Grande do Sul.
The concessionaire emphasized that all sections will have proper signage, in accordance with the Brazilian Traffic Code regulations.
Impact on Safety
The implementation of the new equipment aims primarily at reducing accidents and increasing safety on the region’s highways.
Studies indicate that the presence of radars and speed reducers significantly contributes to the reduction of violations and the severity of accidents, especially in sections with a high rate of collisions.
With the new devices, a decrease in the number of occurrences is expected, along with greater awareness among drivers regarding the importance of respecting speed limits.
Do you believe that the installation of these radars will really reduce the number of accidents? Or do drivers still need more awareness to ensure safety on the highways? Leave your opinion in the comments!
