Traffic lights, however, are not always observed. Always proceed with care. During the Pampas harvest season, pay particular attention to slow moving farm vehicles, which are not a hazard in their own right, but can cause other motorists to become extremely impatient. Also, night driving is inadvisable because of animals on the road in some regions, and drivers who don't always switch on their headlights. Most roads are not divided and are not in good condition.
Highways have also been privatized, so there are now more roads on which to pay tolls.
Parking Parking has been privatized in Buenos Aires allowing entrepreneurial companies to attach wheel clamps or tow away cars that stand too long at a meter. There are a few public underground parking garages and numerous private garages.
