Bangladesh University of Engineering and Technology (BUET) has advised the Bangladesh Road Transport Authority (BRTA) not to extend the lifespan of CNG-run three-wheelers beyond 15 years.
A letter from the BUET expert committee in this regard was received by the road transport regulator on Tuesday, its Secretary Muhammad Showkat Ali told UNB.
About 8,421 CNG-run auto-rickshaws took BRTA permission for plying on Dhaka roads for nine years from 2002. After that timeframe expired, they got six years' extension in three phases which ended on December 31, 2017.
The operators and drivers of the auto-rickshaws have since requested another extension.
Later, BRTA sought assistance of the Ministry of Road Transport and Bridges in taking a decision on the matter.
After deciding in a meeting to seek expert opinion from BUET, the ministry through BRTA allowed the vehicles to ply till March 31, 2018.
Though owners of the CNG auto-rickshaws want another extension, drivers are against it on the grounds of bad condition of the vehicles.
