Every school vehicle shall be equipped with at least one convex mirror not less than 7-1/2 inches in diameter which shall be firmly mounted on the left front corner forward of the seated driver so that he may observe a reflection of the road from the front bumper to a point where direct observation is possible.

Either type shall be independently adjustable.
