The strike will be launched against increasing the minimum fine to 2500 rupees for all vehicles.
Association’s chairman Gemunu Wijerathna said several other private bus associations have also pledged support towards the strike.
However, Minister of Finance Ravi Karunanayake says that as it is the government’s responsibility of assuring road safety, the proposed minimum fine on road violations will not be changed.
He said that lawlessness, including the rampant disregard for road rules, was one of the biggest problems in the country.
Meanwhile, 6 persons have been killed in multiple motor accidents yesterday.
Police said that two children between the ages of 10 and 16 years were among the victims.
The accidents were reported from Moneragala, Kalpitiya, Negombo, Elpitiya, Kekirawa, Giran-duru-kotte and Mahiyanganaya.
14 persons were injured in these accidents.
