Road signs, markings and traffic controlQuestion #15880
What does this road-marking line tell the driver?
Explanation
The approach line is a narrow broken line whose dashes are three times longer than the gaps. It warns the driver that a solid line, which will not be allowed to cross, is coming up. The approach line itself may still be crossed from either side.
