3.  Parking brakes.
A vehicle, except a 2-wheel motorcycle, must be equipped with parking brakes adequate to hold the vehicle on any grade on which it is operated, under all conditions of loading, on a surface free from snow, ice or loose material. Parking brakes:
A. Must be capable of being applied by the driver's muscular effort, spring action or equivalent means;   [PL 1993, c. 683, Pt. A, §2 (NEW); PL 1993, c. 683, Pt. B, §5 (AFF).]
B. May be operated with assistance of the service brakes or other source of power, provided that failure of the service brake actuation system or other power assisting mechanism does not prevent the parking brakes from being applied;   [PL 1993, c. 683, Pt. A, §2 (NEW); PL 1993, c. 683, Pt. B, §5 (AFF).]
C. Must be designed so that, once applied, they remain applied with the required effectiveness despite leakage or exhaustion of any source of energy;   [PL 1993, c. 683, Pt. A, §2 (NEW); PL 1993, c. 683, Pt. B, §5 (AFF).]

E. If the means of applying the parking and service brakes are connected, must be constructed so that failure of one part does not leave the vehicle without operative brakes.   [PL 1993, c. 683, Pt. A, §2 (NEW); PL 1993, c. 683, Pt. B, §5 (AFF).]
[PL 2005, c. 577, §23 (AMD).]

F. A dolly axle, so-called, on a farm truck transporting agricultural products and supplies.
A dolly axle may not be considered in determining the gross weight or axle limits permitted on the vehicle.
A 2-axle or 3-axle farm truck equipped with a dolly axle is considered a 2-axle or 3-axle vehicle.   [PL 1993, c. 683, Pt. A, §2 (NEW); PL 1993, c. 683, Pt. B, §5 (AFF).]
