A report by the General Audit Office (AGN, for its acronym in Spanish) states that checks on the safety of transportation units of cargo and passengers are "lax", they are carried out in the cheapest workshops authorized by the National Transportation Commission (CNRT, for its acronym in Spanish), and "lack the accuracy to ensure the approval of the vehicles."
The obligatory verifications of the cars by the outsourced work are done in the workshops of Technical Review (TRT), and the control of the CNRT in the headwaters of the companies. The conclusion of the AGN is based on the existence of workshops with "very different characteristics and, therefore, heterogeneous services" which do not have the necessary equipment for the verifications and, secondly, that the CNRT itself does not have a homogeneous criterion to audit and authorize the operation of the TRT. In addition, as carriers can choose which workshop to attend and the fare is not uniform, the most referred to TRT are those with the lowest fares and at the same time, those are the ones that offer "a more lax control." In fact, in 2005, the Technical Manager of the CNRT itself noted that "in this scheme business is considered far more than safety" and that the action should be "reversed". In 2002 the AGN retook these findings in a 2007 report on the psychophysical transport of the driver’s test.
Something that the Watchdog states is that the percentage of rejections of the TRT units analyzed quadruples in those days when the CNRT inspections workshops although simultaneously the number of vehicles checked during visit of the Commission decreases. Although the rejection rate of the TRT is around 15% where the AGN team accompanied the staff of the CNRT in their inspections, disapprovals did go below 60 percent.
In the 2007 study, the AGN adds that "the CNRT does not timely sanction violators’ workshops , so the whole control system is weakened," and points out that "punitive procedures" begin between "90 and 300 working days" after an irregularity is detected. The Audit team verified that the sanctions imposed in the years 2000 and 2003 were completed in 2005.
Furthermore, the checks the CNRT carries out on the transport headers, according the AGN it is a "serious problem" the amount of tax assessments that need to be solved. There are about 50,000 records and, if the CNRT solves about 35 folders per day, as reported, it would take more than five years to complete the task, without considering that 200 files enter per day.
