Northern Territory Consolidated Regulations Northern Territory Consolidated Regulations(1) One sustained application of the brake of a motor vehicle built after 1930, or a combination that includes a motor vehicle built after 1930, must be able to produce the performance mentioned in subrules (2) to (7):
(a) when the vehicle or combination is on a dry, smooth, level road surface, free from loose material; and
(b) whether or not the vehicle or combination is loaded; and
(c) without part of the vehicle or combination moving outside a straight path:
(i) centred on the longitudinal axis of the vehicle or combination before the brake was applied; and
(ii) 3.7 metres wide.
(2) The braking system of a motor vehicle or combination with a gross mass under 2.5 tonnes must bring the vehicle or combination from a speed of 35 kilometres an hour to a stop within:
(a) 12.5 metres when the service brake is applied; and
(b) 30 metres when the emergency brake is applied.
(3) The braking system of a motor vehicle or combination with a gross mass of at least 2.5 tonnes must bring the vehicle or combination from a speed of 35 kilometres an hour to a stop within:
(a) 16.5 metres when the service brake is applied; and
(b) 40.5 metres when the emergency brake is applied.
(4) The braking system of a motor vehicle or combination with a gross mass under 2.5 tonnes must decelerate the vehicle or combination, from any speed at which the vehicle or combination can travel, by an average of at least:
(a) 3.8 metres a second a second when the service brake is applied; and
(b) 1.6 metres a second a second when the emergency brake is applied.
(5) The braking system of a motor vehicle or combination with a gross mass of at least 2.5 tonnes must decelerate the vehicle or combination, from any speed at which the vehicle or combination can travel, by an average of at least:
(a) 2.8 metres a second a second when the service brake is applied; and
(b) 1.1 metres a second a second when the emergency brake is applied.
(6) The braking system of a motor vehicle or combination with a gross mass under 2.5 tonnes must achieve a peak deceleration of the vehicle or combination, from any speed at which the vehicle or combination can travel, of at least:
(a) 5.8 metres a second a second when the service brake is applied; and
(b) 1.9 metres a second a second when the emergency brake is applied.
(7) The braking system of a motor vehicle or combination with a gross mass of at least 2.5 tonnes must achieve a peak deceleration of the vehicle or combination, from any speed at which the vehicle or combination can travel, of at least:
(a) 4.4 metres a second a second when the service brake is applied; and
(b) 1.5 metres a second a second when the emergency brake is applied.
(8) The parking brake of a vehicle or combination must be able to hold the vehicle or combination stationary on a 12% gradient.
