The state transport department is planning to allow registered autorickshaws without permits to ply on existing routes or on ones where three-wheelers have been operating illegally to hasten their switch to LPG.
Around 30,000 autorickshaws in Calcutta, Howrah and North and South 24-Parganas are registered with the transport authorities but have not been allotted permits.
