What is the difference between a fork road sign and an intersection sign?

[HZoe]

Intersection advance signs indicate distance and geographical information, showing lane directions for straight, turning, etc., which are lane direction advance signs. A crossroad is indicated by a cross-shaped guide sign, with the top of the cross pointing straight, the left end indicating left, and the right end indicating right. Additional information: Precautions for driving at crossroads: Precautions 1: To drive north, you can make a U-turn by yielding to normally moving vehicles, regardless of whether the light is red or green, unless there is a dedicated U-turn red light. Precautions 2: To drive south, obey the north-south traffic lights; when the light is green, merge south into the lane but be cautious of vehicles turning right from north to west. Precautions 3: To drive west, follow right-turn rules and yield to vehicles from all directions entering the far-right lane. Precautions 4: To drive east, obey the east-west traffic lights but be mindful not only of right-turning vehicles from the north but also those from the south.
