Prescribed traffic signs
2.—(1)  Subject to any directions which the Minister may give under section 119 of the Act, the traffic signs authorised to be drawn or placed on or near any road shall —
(a)be at least of the size, and conform to the colour and type as prescribed in the diagrams set out in the Schedule; and
(b)conform to the descriptions set out in these Rules.
(2)  The dimension of the traffic signs as given in the diagrams set out in the Schedule denotes the dimension in millimetres unless otherwise stated.
(3)  A traffic sign drawn or placed on or near a road shall be deemed to be a prescribed traffic sign and to have been so lawfully drawn or placed unless the contrary is proved.
(4)  The fact that a traffic sign differs slightly in size, colour or type from that prescribed in these Rules shall not prevent the traffic sign from being a regular or lawful sign so long as the sign is not thereby misleading or its general appearance materially altered or its effectiveness impaired.
Types of traffic signs
3.  The traffic signs set out in the Schedule are divided as follows:
(a)regulatory signs as set out in Part I of the Schedule which are intended to inform road users of special obligations, restrictions and prohibitions with which they must comply and are subdivided into —
(i)mandatory signs;
(ii)priority signs; and
(iii)prohibitory or restrictive signs;
(b)warning signs as set out in Part II of the Schedule which are intended to warn road users of the danger on the road and to inform them of the nature and source of the danger; and
(c)informative signs as set out in Part III of the Schedule which are intended to provide road users with information which may be useful while they are travelling.
Inscriptions on signs
4.  The inscription on the traffic signs shall be in the English language except that there may also be inscription in another language or languages on the signs.
Change of directions
5.  The direction of any arrow or other indication on the signs shown in the diagrams in the Schedule may be reversed or otherwise varied as circumstances may require.

(A)is on a lane from which a left turn or a right turn may, by virtue of any sign or marking as shown in the Schedule, be made; and
(B)in compliance with the illuminated red light, has stopped at the stop line or broken lines on the road provided in conjunction with the signals,
may, with caution and due regard to the safety of other users of the road and precedence to pedestrians and to traffic in other directions, proceed beyond the stop line or broken lines and make a left turn or a right turn, as the case may be.
