Madhyamik, the school leaving examination conducted by the West Bengal Board of Secondary Education, began Tuesday.
The accident occurred when the auto-rickshaw somehow got inside the convoy of the minister who was on the way to his office.
The minister said he arranged for vehicles to carry the examinees to their examination centre and helped one of the guardians get first aid in a local hospital.
There had been some minor damage to the car carrying Mallick.
The minister expressed unhappiness that a section of the auto-rickshaws did not follow traffic rules.
