Warning Sign/Side Road
|Old style side road ahead|
|TSRGD ref :||506.1|
Early examples had an equal width horizontal and vertical stroke, with the horizontal stroke able to be varied to the left or right.
The modern sign has a wider vertical stroke with a point, and a narrower side stroke, which may be varied to the left or right.
Later variations include the side road having priority, with a wider stroke to the side than the road carrying on ahead.
