C.A municipal delivery parking badge

D.An international driving permit (IDP) issued by the Automobile Club Argentino (ACA)

Explanation: Disposición ANSV 54/2025 (integrated by Disposición ANSV 219/2025) substituted the old LiNTI regime: the professional Licencia Nacional de Conducir classes C, D and E now themselves carry interjurisdictional character for cargo and passenger transport across the country. They are granted by delegated provincial/CABA authorities, with formation courses and psychophysical exams delivered by prestadores registered (free of charge) with the ANSV.

4Which specific class and subclass of license is required to operate an emergency ambulance (ambulancia de emergencia) in Argentina?

A.Class B.1

B.Class D.4 (Servicios de urgencia, emergencia y similares), which must be held together with the base subclass corresponding to the vehicle (A, B, C, D or E)

C.Class C.2

D.Class E.1

Explanation: Under the current official subclass structure of the Licencia Nacional de Conducir, Class D.4 is designated for vehicles of urgency, emergency and similar services (ambulances, fire apparatus, civil protection units), and it must accompany the base subclass matching the vehicle. Note that Class D.3 is a different subclass: passenger transport vehicles with more than 20 seats.

5What is the legal maximum blood alcohol concentration (BAC) permitted for professional drivers operating under Classes C, D, or E in Argentina?

A.0.5 grams per liter of blood

B.0.2 grams per liter of blood

C.Strictly 0.0 grams per liter of blood (tolerancia cero)

D.0.8 grams per liter of blood

Explanation: Under Article 48 of Ley 24.449 and Ley 27.714, professional and commercial drivers are held to a strict zero tolerance standard (0.0 g/l). Any detectable blood alcohol level results in immediate license suspension, heavy fines, and vehicle disqualification.

6What is the primary function and legal purpose of the on-board Tachograph (Tacógrafo) installed in commercial buses and heavy trucks in Argentina?

A.To automatically pay highway tolls via wireless RFID

B.To continuously record vehicle speed, driving time, distance traveled, and rest intervals on chart discs or digital memory for regulatory compliance

C.To measure engine oil viscosity and cabin temperature

D.To restrict the vehicle engine from exceeding 2,000 RPM

Explanation: Under CNRT regulations and Ley 24.449, the tachograph is a mandatory recording instrument that continuously tracks speed, running time, stops, and distance. Transport operators must archive discs/digital logs for inspection by CNRT auditors and police.

7Under the Argentine driving-time rules applied to professional road cargo transport, what rest pause must a driver take after 4 hours of continuous driving?

A.No pause is required until the full daily driving limit is reached

B.A rest pause of at least 30 minutes (which may be fractioned as regulated)

Licencia Profesional Clases C/D/E Study Tips from Top Performers

1Understand compressed air brake operations: compressor cut-out pressure is ~8 bar (115-120 psi) and cut-in is ~6 bar (85-90 psi); drain air tanks daily to remove moisture and oil condensation.

2Memorize statutory axle weight limits under Ley 24.449 Art. 53: single axle with single tires 6 t, single axle with dual tires 10.5 t, tandem 18 t, tridem 25.5 t; conventional combinations reference 45 t gross, while duly regulated configurations such as bitrains can reach 75 t (Decreto 689/2026).

3Remember Kemler hazard codes: doubling a digit indicates intensification of that hazard (e.g., 30 = flammable liquid, 33 = highly flammable liquid), and an 'X' prefix means the substance reacts violently with water.

4Review downhill driving techniques: select the correct lower transmission gear before descending and use engine compression brakes / driveline retarders to avoid overheating foundation drum/disc brakes.

5Understand the causes of jackknifing (efecto tijera): locking the tractor drive wheels while braking on slippery pavement causes the semitrailer to swing out and jackknife.

6Know driving and rest rules: cargo transport drivers must take a rest pause of at least 30 minutes after 4 hours of continuous driving within the daily limits of the applicable labor framework, all monitored through the tachograph; professional drivers are held to a strict 0.0 g/l alcohol tolerance.
