(a) Each trailer or semitrailer having a gross weight of three thousand pounds or more shall, when operated on any public highway, be equipped with a braking system operating on all wheels. The braking system shall be adequate to safely control the movement of the trailer or semitrailer and, when set, to safely hold the trailer or semitrailer stationary. The brakes shall, at all times, be maintained in good and sufficient working order and shall be capable of being controlled or operated from the driver’s seat of the towing vehicle by either the hand or the foot, except that brakes on trailers having a gross weight of eight thousand pounds or less need not be capable of being controlled or operated from the driver’s seat by either the hand or the foot. Except with respect to pole trailers and boat trailers, the commissioner may make regulations concerning the performance of such brakes when the trailer or semitrailer is operated in combination with a towing vehicle. The regulations shall designate the stopping distance, in feet, of the combination of trailer or semitrailer and shall include such other conditions as may be necessary to ensure brake performance adequate to safely control the movement of the vehicles.

      (b) Any person who violates any provision of this section shall be deemed to have committed an infraction and be fined not less than thirty-five dollars nor more than fifty dollars for each offense.
