NASHVILLE — A federal transportation panel on Tuesday recommended to states that all new large school buses be equipped with both lap and shoulder seat belts, which the board chairman called a ‘‘tried and true’’ safety protection.

The National Transportation Safety Board approved the recommendation Tuesday. It also recommended requiring collision-avoidance systems and automatic emergency brakes on new school buses.

The recommendations, which aren’t binding, came just days after a school bus collided with a truck in New Jersey, killing a student and teacher.

Chairman Robert Sumwalt said the board’s last recommendation about school seat belts, made in 2013, was that states consider them, which he called ‘‘sort of weak.’’

He said it’s time for the agency to take a hard stance.
