BEIJING, Feb. 19 (Xinhua) -- Chinese authorities will standardize all the primary school buses to ensure safety of pupils when they commute between home and school.

The school buses refer to those that are able to carry more than 10 children. The set of standards, the first of its kind in the country, require the school buses to bear unified tag, according to the Beijing News on Friday.

The tag features two school children on two separate pages of an unfolded book.

According to the standards, school buses should have seat belts for each seat and there should be one seat or more for caretakers.

Double-deck bus and articulated bus are not allowed to serve as primary school buses for safety concern.

The standards also require the bus makers to install a device to record the driving speed, time and mileage of the vehicle.

The standards, jointly issued by the General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ) and the Standardization Administration, will come into force on July 1.
