Tamil Nadu’s government bus fleet is facing fresh safety concerns after transport trade unions alleged that substandard spare parts, including tyres, are affecting maintenance and increasing risks for passengers. The allegations were reported from Madurai by Dinamalar on September 17, 2026.
The report said a government express bus travelling from Tiruchirappalli to Chennai suffered a front-tyre burst last year, killing seven people. Trade union representatives alleged that the Transport Department had not taken effective action after the incident and claimed that hundreds of government buses had suffered tyre-burst-related accidents over the following six months.
The latest incident cited in the report occurred on a government bus travelling from Kumily to Nagercoil a few days ago. Its front tyre reportedly burst and the bus moved uncontrolled on the road before the driver’s handling prevented passengers from being injured. The report did not provide the exact date, passenger count or location of the incident.
Tamil Nadu’s government transport corporations operate more than 20,000 buses, according to figures cited in the report. These services carry 2.03 crore passengers every day, making the condition of fleet components a public-safety concern that extends beyond individual depots or routes.
The trade unions alleged that the quality of spare parts was not being adequately verified during procurement. They said the use of inferior components could increase costs for the government by leading to repeated repairs and replacements, while also placing passengers at risk. The unions also said continuing accidents had reduced public confidence in government bus services.
They called for a comprehensive inspection of spare parts currently held in stock and the removal of components found to be substandard. The unions further demanded an inquiry into possible irregularities in spare-parts procurement during the past five years and action against those found responsible.
The representatives also sought stronger monitoring systems to ensure that quality standards are maintained without compromise in matters involving bus safety. The report did not include a response from the Tamil Nadu Transport Department or the state transport corporations to the allegations, nor did it provide official accident statistics or procurement records.
The immediate questions raised by the report concern how spare parts are tested before procurement, how components are inspected after delivery and whether depots have an effective mechanism for withdrawing defective stock. Any official investigation or response from the Transport Department would establish the next steps on these issues.
