Never let a fleet vehicle's RTO lapse unnoticed
In Argentina vehicles not in private use must pass the mandatory technical inspection (RTO) with a validity of no more than twelve months; the first is due within a grace period of at most twelve months from first registration (Decree 779/95, Annex 1, Article 34(5) and (6)). The certificate lapses with it.
Argentina's Traffic Act 24.449 requires periodic technical inspection of all motor vehicles, trailers and semi-trailers used on public roads, to check the parts and systems that affect their active and passive safety and their emissions; the frequency is set by the implementing regulations (Article 34 of the Act).
Under those regulations, the local authority may set longer periods than the general ones for private vehicles, but for vehicles that are not in private use the Mandatory Technical Inspection (Revisión Técnica Obligatoria, RTO) cannot be valid for more than twelve months. These vehicles take their first RTO as the local authority decides, and it cannot allow a grace period of more than twelve months from first registration (Decree 779/95, Annex 1, Article 34(5) and (6)).
Each inspection is evidenced by a Technical Inspection Certificate (CRT), which is reported to the Transport Secretariat so its validity can be checked. The inspection centre also issues a sticker for the front windscreen and a digital certificate with the same validity (Article 34(4)). The CRT expires automatically when the inspection's validity ends (Article 34(21)).

Act 24.449 applies in federal jurisdiction, and provinces and municipalities may adhere to it (Article 1 of the Act). Different periods apply to vehicles in private use (Annex 1, Article 34(6)).
Who is responsible?
The Act gives the competent authority the task of carrying out the inspection, which it may delegate to official dealers or authorised workshops (Article 34 of Act 24.449). The Transport Secretariat is the authority for the RTO system and registers the inspection centres (Annex 1, Article 34(1)). Each centre operates under the technical direction of a registered engineer, who issues and signs the CRT (Article 34(12) and (21)).
If the deadline passes
Vehicles found without an RTO within the periods in points 5 and 6 can be ordered by the local authority to take it without delay, without prejudice to the applicable penalties; vehicles that cannot show an RTO may not leave the jurisdiction where they are registered until they comply (Annex 1, Article 34(7) and (8)). With a conditional result the vehicle may not be driven once the deadline given has passed; with a rejected result it may not be driven and needs a full new inspection (Article 34(17) and (18)).
Conditional or rejected: two different outcomes
The inspection centre rates each vehicle as fit, conditional or rejected. A vehicle not in private use that is rated conditional has at most thirty days for re-inspection and may not provide transport services in the meantime. If it does not return for the second inspection within the time given, the centre reports it to the local authority (Annex 1, Article 34(17) and (19)).
