			 inch. The other means shall be a manually controlled device readily operable by
			 a person seated in the driving seat. Its emergency position or method of

			 truck tractor and truck when used for towing other vehicles equipped with
			 vacuum brakes, shall have, in addition to the single control required by s.
			 Trans
			 308.06 to operate all brakes of the combination, a
			 second manual control device which can be used to operate the brakes on the
			 towed vehicles in emergencies. Such second control shall be independent of
			 other controls, unless the braking system be so arranged that failure of the
			 pressure on which the second control depends will cause the towed vehicle
			 brakes to be applied automatically. The second control is not required by this
			 rule to provide modulated or graduated braking.
(3) Air brake systems installed on towed
			 vehicles shall be so designed, by the use of "no-bleed-back" relay emergency
			 valves or equivalent devices, that the supply reservoir used to provide air for
			 brakes shall be safeguarded against backflow of air to the towing vehicle upon
			 reduction of the towing vehicle air pressure.
(4) The requirements of subs. (2) and (3)
			 shall not be applicable to motor vehicles in driveaway-towaway
			 operations.
