The National Commission for Transport Regulation (CNRT, for its acronym in Spanish) solved ten of the 47 irregularities the inspection bodies found in 2006 in the areas of railway concessions, level crossings, and motor transport. This effectiveness, just over 20 percent, was detected by the Comptroller General's Office (SIGEN, for its acronym in Spanish) in a study that also adds that the internal audit work of the Commission is "inappropriate and shows high probability of errors that expose the organization to risks of great magnitude" to occur.

Some train operating companies have a "high degree of non-compliance with quality standards in their service," explains the work of the receivership, adding that the processing of files to punish those failures, task of the CNRT, "takes a severely unreasonable amount of time." Furthermore, the providers do not pay fines arising from its deficiencies, or pay the amount that corresponds. In the area of railway concessions only a third of the shortcomings arising from audits carried out in 2006 were regularized (two of six). 

Apart from the data, the SIGEN says "the number of steps in each level inspected is low," adding that the CNRT "has no approved inspection programs, nor are they made with a pre-established criteria." The percentage of solution irregularities in this area is still lower than the railway concessions: over six flaws, only one was regularized (17%).

The lowest level of effectiveness in normalizing control shortcomings recorded in transportation, 9 percent (one of 11). The SIGEN highlighted irregularities in controls of the requirements for "access to the share of diesel to tiered pricing" systems, mandatory technical review, and clearances of vehicles for the disabled.

Other deficiencies that the report detected of the Trustee deal with purchases and contracts made by the CNRT by higher than market values, and the "absence" of an integrated monitoring system of fines, payment of debtors, and recidivism. In addition, the care sector users do not have documentation were they can leave complaints. Moreover, "at the time of budgeting, management proposals are not adequately substantiated expenditure requirements," concludes the SIGEN.
