Three-wheelers will be allowed to make minor modifications only, said the Department of Motor Traffic.
Its assistant commissioner Sujeewa Tennakoon said three-wheelers modified in such a way that disrupts or harms other vehicles or pavement users will not be allowed to be on the roads.
He said the motor traffic inspector in the respective district secretariat should issue a report approving any modifications.
As much as two million of the estimated eight million vehicles in Sri Lanka are three-wheelers.
