THIRUVANANTHAPURAM: Center has stepped in to address the alarming rise in petrol vehicles failing smoke inspections following a software update by the Motor Vehicles Department. The recent data indicates a significant spike in failures with 3,276 out of 31,657 tested petrol vehicles on the 3rd failing the inspection.

Before the software change, only 536 out of 39,274 petrol vehicles failed the test over the previous two years. The ministry attributes the increase in failures to technical faults especially related to fuel combustion and has mandated corrections before vehicles are deemed roadworthy.

Starting from 2021, the state issues smoke certificates online with the new software collecting data and calculating exhaust gas amounts including carbon monoxide levels. The analysis reveals the need for corrective measures in the inspection process.

To address smoky vehicles, adjustments to the nozzle were previously allowed allowing external oxygen to enter during testing. However, this practice is now prohibited, as excessive oxygen will result in failure. The ministry is also considering tightening the inspection process for diesel vehicles.

The flaws in the smoke inspection system are evident, prompting a revaluation of the process. The state which boasts 2,600 smoke testing centers is taking steps to rectify the situation and ensure road safety.
