Mexico and Argentina traffic safety guidelines released

In Mexico, officials stress that car horns should be used only briefly to warn other road users and prevent accidents, as mandated by traffic law. Excessive or inappropriate horn use, such as prolonged honking, greeting friends, or sounding the horn at night, can increase stress among drivers and trigger fines and points on a driver’s license.

In Argentina, a distinctive diamond‑shaped traffic sign (P. 33) featuring a red triangle on a yellow background and a large number warns motorists of an upcoming regulatory sign. The displayed number indicates the distance to the sign, allowing drivers to adjust speed and prepare for changes in road rules, thereby improving safety and reducing the risk of violations.
