1. Tunnel
A tunnel is a covered passage that carries a road through or beneath an obstacle such as a hill, mountain, building, waterway or another transport route. Road tunnels may contain one or more traffic lanes and can carry traffic in one or both directions.
Driving in a tunnel requires particular attention because visibility, available escape routes and space for avoiding hazards are limited. Drivers should follow the applicable lighting, speed, lane and following-distance rules and pay attention to emergency exits, traffic signals and variable-message signs.
What should I check before entering a tunnel in Argentina?
Check the tunnel’s signs and the applicable provincial or local rules. Where National Traffic Law 24,449 applies, obey traffic controls and maintain a speed that lets you control the vehicle safely in the actual conditions.

Does a tunnel sign in Argentina set a universal speed limit?
No single speed can be read from the tunnel pictogram. Apply the road’s relevant limit and any permanent or electronic speed restriction, and drive more slowly when visibility, queues or another hazard require it.
Is every tunnel in Argentina open to pedestrians and cyclists?
No. Check the road category and access signs before entering. A motorway tunnel, a vehicle-restricted tunnel and a purpose-built walking or cycling underpass have different access arrangements. Emergency evacuation routes do not establish ordinary public access.
