About the Licencia C3 — Vehículos Articulados de Servicio Público Exam
The Category C3 driving license in Colombia authorizes public-service articulated vehicles (vehículos articulados de servicio público). It is obtained by complementary recategorization from an active C2 license. Resolución 4100 de 2004 defines normal freight configurations and their dimensional, gross-weight, and axle limits; a 3S3 configuration is one example, not the definition of Category C3. Drivers in public freight operations must use the RNDC manifest when the operation requires it, obey active official weight-control directions, and observe Article 107's 80 km/h cap for public-service cargo. Core vehicle knowledge includes fifth-wheel and kingpin coupling, pneumatic brake circuits, trailer off-tracking, jackknife prevention, descent control, and emergency escape ramps. Circular 0317 of 28 August 2026 deferred CALE operation. This English MCQ bank is a study adaptation and does not simulate the official attitude scale or practical tests.

Licencia C3 — Vehículos Articulados de Servicio Público: Suggested Study Strategy
Frequently Asked Questions
What vehicle types are authorized under Category C3 in Colombia?
Category C3 is the public-service articulated-vehicle category, covering combinations such as tractocamiones with semitrailers. C2 is the category specifically defined for public-service rigid trucks, busetas and buses; higher-category privileges should be applied according to the current licensing hierarchy rather than describing C3 as incapable of authorizing every lower vehicle.
Is Category C3 called 'Doble Troque'?
No. Calling C3 'doble troque' is a common misconception. In Colombia, 'doble troque' refers to a three-axle rigid truck (camión rígido de tres ejes), which is classified under Category C2. Category C3 officially designates articulated public vehicles (vehículos articulados de servicio público), which consist of a tractor unit and one or more trailers or semi-trailers.
What are the prerequisites to obtain a Category C3 license?
Applicants must be at least 18 years old, be literate, possess an active and valid Category C2 license (as C3 is obtained strictly through complementary recategorization training), be registered in RUNT, hold an approved CRC medical and psychophysical fitness certificate, and present a certified complementary C3 course diploma from an authorized Centro de Enseñanza Automovilística (CEA).
What is the structure and passing score of the theoretical exam for Category C3?
Under Resolución 20253040037125, the theoretical examination consists of 40 questions (12 attitude-scale items and 28 technical knowledge questions) administered over 70 minutes. Candidates must score at least 80% on the knowledge component AND at least 80% on the attitude component independently to pass.
What is the current operational status of the independent CALE examination?
While Resolución 20253040037125 designed independent evaluation through Centros de Apoyo Logístico de Evaluación (CALE), Circular 0317 of 28 August 2026 deferred CALE entry into operation and the mandatory certificate requirement pending a full administrative review. In the interim, examination and graduation protocols remain coordinated through accredited CEAs.
What is the maximum speed limit for a C3 articulated cargo combination on Colombian national highways?
Under Ley 2251 de 2022 (Ley Julián Esteban) modifying Article 107 of Ley 769 de 2002, the maximum permissible speed for public cargo transport vehicles on national and departmental highways is capped at 80 km/h, regardless of whether passenger vehicles are permitted up to 90 km/h or 120 km/h on dual carriageways.
What is the maximum gross vehicle weight permitted for a 3S3 articulated combination under Resolución 4100 de 2004?
Under Resolución 4100 de 2004, a 3S3 combination (three-axle tractor coupled to a three-axle semi-trailer / tridem) has a maximum gross vehicle weight (Peso Bruto Vehicular - PBV) limit of 52 metric tonnes.
