How to make texture to the left or right this is only straight texture?

By left or right, do you mean the curved markings?
It is necessary to have the roads with quad geometry, to be able to apply the texture correctly.

Otherwise, taking into account that the road sections have different widths, between 5.85 and 6.87 m, it is possible to make the markings easier with Line, Arc and Offset.

Sorry i cant get it. What did you do after 00:17? Im trying to do but still cant do..

You need the same number of vertices on both sides. You have one with 24 and the other with 25.
Make sure you create quads (a face with 4 edges).

Thank you!
