What signpost is this?

This is a road sign for going straight, but it is not standardized.

Straight road signs are usually traffic signs or signs, which indicate the direction and route of straight roads or intersections. This kind of road sign is usually used to tell drivers and pedestrians to continue driving along the route and not to turn. Straight road signs are generally arrow-shaped and point forward, and sometimes they may be accompanied by written instructions, such as "Go straight" and "Go forward".

Through road signs are very important at road intersections or complex road networks, because they can help drivers know the correct driving direction and avoid getting lost or causing traffic chaos. These road signs are usually standard traffic signs, which are set on roads to provide clear instructions to ensure smooth and safe traffic.

It should be noted that the design and specifications of traffic signs in different areas may be slightly different, but in general, the meaning of the straight road sign is to indicate the straight direction of the road ahead.
