Paragraph 4 Traffic light signalsI1

Sub-paragraph (2) applies to the red, amber and green light signals shown in the diagram in column 3 of the Part 2 sign table at each of items 1 to 4 (types of traffic light signals), including, for items 1 and 3, when, as described in paragraph 2(6), the green signal is a green arrow.

The order of illumination for the light signals must be as follows—

The duration of the period when the red and amber light signals are illuminated together must be 2 seconds.

The duration of the period when the amber light signal is illuminated on its own must be 3 seconds.

The requirement in sub-paragraph (3) or (4) is to be treated as having been met if the duration is 0.25 seconds more, or less, than that specified.
