Traffic Alert
Reduced visibility due to fog on Buenos Aires city highways. Maximum caution advised.
Fog Blankets Buenos Aires Highways
On Thursday, August 20, 2026, the first minutes of the morning were shrouded by a dense fog that significantly reduced visibility on the highways crossing the City of Buenos Aires (CABA), the capital of Argentina. The phenomenon appeared at the start of the workday, causing delays and requiring drivers to take extra precautions.
Traffic journalist Ernesto Arriaga shared the alert at 7:38 AM via his X account (formerly Twitter), tagging the official accounts of AUSA (Autopistas Urbanas S.A.), the city's highway operator, as well as Leandro Grandinetti, the Head of Government of Buenos Aires, and the traffic account Maria Fortaleza. In his message, he urged drivers to proceed with utmost care.
What Is Fog and Why Is It Dangerous?
Fog is a meteorological phenomenon consisting of tiny water droplets suspended in the air, reducing horizontal visibility to less than one kilometer. While driving, this condition makes it difficult to judge distances and speeds, dramatically increasing the risk of chain-reaction collisions.
Driving Tips for Foggy Conditions
- Reduce speed and increase the following distance.
- Use low beams and fog lights (not high beams, which reflect and cause glare).
- Do not stop on the road. If visibility is zero, find a safe place to pull over.
- Avoid overtaking maneuvers.
