        (a)  Parking brakes.--Every vehicle or combination, except a
     motorcycle, operated on a highway shall be equipped with a
     parking brake system adequate to hold the vehicle or combination
     on any grade on which it is operated, under all conditions of
     loading, on a surface free of ice or snow. The system shall not
     be designed to require a continuous or intermittent source of
     energy for full effectiveness after initial application.
        (b)  Service brakes.--Every vehicle and combination operated
     on a highway shall be equipped with a service brake system
     adequate to control the movement of and to stop and hold the
     vehicle or combination on any grade on which it is operated,
     under all conditions of loading, and adequate to meet the
     braking performance standards established by regulation of the
     department.
        (c)  Breakaway systems.--Every combination operated on a
     highway, the towed vehicle of which is equipped with brakes or
     which has a gross weight in excess of 3,000 pounds, shall be so
     equipped that, upon breakaway of the towed vehicle, the towed
     vehicle shall be stopped and held automatically, and the towing
     vehicle shall be capable of being stopped and held by use of its
     own service braking system.
        (d)  Exceptions.--This section does not apply to towed
     instruments of husbandry and such items or types of special
     mobile equipment or commercial implements of husbandry as are
     specifically exempted from compliance by regulations promulgated
     by the department.
