After recording deposition of the plaintiff and a witness on Monday, Dhaka Metropolitan Sessions Judge KM Imrul Kayes adjourned the hearing until Tuesday.
He also said he would hear the case every working day until Nov 22.
Jahangir Alam, the father of one of the dead students, Dia Khanom Mim, started the case after a bus of the Jabale Nur transport ran over several students of Shaheed Ramiz Uddin Cantonment College and killed Dia and Abdul Karim.
The accident triggered a countrywide student movement for safe roads that brought traffic to a standstill for around a week. The government promised the protesters steps to meet their demands in a bid to bring the situation under control.
In the sensational case, 41 people were named as witnesses. Three Jabale Nur buses and the driving licences of the drivers were also seized as evidence.
The court started recording the statements of the witnesses on Nov 1 after framing the charges against the six accused on Oct 25.
The accused behind bars are Md Shahadat Hossain Akondo, owner of one of the buses, driver Masum Billah and his helper Md Enayet Hossain and Md Zobayer Sumon, driver of the second bus.
The owner of the second Jabale-Nur bus, Md Jahangir Alam, and his helper Md Asad Kazi are on the run.
Inspector Kazi Shariful Islam, who pressed charges against the six, said in the chargesheet that one of the three buses ran over the students while racing.
