What does this motorway sign mean?

Why this is the answer

Four amber lights flash in alternate horizontal pairs to provide a warning and to draw the driver's attention to the message displayed.

Why the other answers don't fit

B
1 tonne weight limit ahead — A weight limit is shown in a red ring with the figure in tonnes.
C
Left-hand lane closed ahead — The sign shows which lane is closed, and here it is not the left.
D
T-junction 1 mile ahead — A junction is shown by the shape of the roads, not by a lane diagram.

Where this question comes from

The question, its options and the explanation are reproduced word for word from the DVSA revision question bank under licence. The licence requires them to appear unaltered, so we cannot reword them and neither can anyone else — that is why you will meet the same wording on other sites. Everything else on this page is written by Theory Hub: the explanation of why each wrong answer is wrong, the topic guide and the revision notes.
