Full text
44. In a drift where motor vehicles travel but not on rails, the width of the travelway shall exceed by at least 1.5 m (4.9 ft) the outside width of the vehicles that travel there. The travelway shall be at least 2 m (6.6 ft) wider than the outside width of the vehicles travelling there if the travelway is used by pedestrians at the same time, unless safety bays are installed in accordance with paragraph 2 of section 43.
However, this section does not apply where motor vehicles not on rails are used solely to dig a travelway.
Where the travelway to be dug shall exceed 60 m (196.9 ft) in length, its width shall exceed by at least 1 m (3.3 ft) the outside width of the motor vehicles travelling therein and safety bays shall be installed in accordance with paragraph 2 of section 43.
