Regarding the rise in road accidents in July, Road Safety Foundation executive director Saidur Rhaman told Prothom Alo that Eid was celebrated at the beginning of this month and road accidents increased during Eid.
Besides, the government could not control the movement of motorcycle entirely. The Road Transport Act has not been implemented while surveillance is no more in place now a days. Moreover, restlessness among people has increased, Saidur Rahman added.
The government also restricted movement of motorcycle during Eid-ul-Azha, with banning inter-district movement of bike except for emergency.
Yet, 33 per cent of the deaths caused by road accidents in July were bike riders.
