Hong Kong Regulations

HOUSING (TRAFFIC) BY-LAWS - BYLAW 33

Presumption as to signs or road markings

A sign erected on, in or near, or a road marking placed on or in a restricted
road or car park which is similar to a sign or road marking specified in these
by-laws shall be deemed to be a sign or road marking in accordance with these
by-laws and to have been lawfully so erected or placed unless the contrary is
proved, and the fact that a sign or road  marking differs slightly in size,
colour or type from a specified sign or road marking shall not prevent such
sign or road marking from being a specified sign or road marking so long as
the general appearance of the sign or road marking is not thereby materially
impaired. (L.N. 418 of 1984)
