Two-Way Traffic Warning Sign - Road Safety Symbol Explained #257101 (License: Personal Use)

The image shows a regulatory warning sign in the shape of an equilateral triangle with a thick red border and white background. Inside, two bold black arrows-one pointing upward and one downward-indicate that traffic will flow in both directions ahead. This sign is commonly used where a single-lane road transitions to a two-way configuration, often after a section of one-way traffic or near intersections.

Used on roads in Europe and other regions following the Vienna Convention on Road Signs and Signals, this sign appears on roadside posts or overhead gantries to warn drivers before they enter a two-way stretch. It matches user intent for understanding road signage, driver education, or preparing for a driving test.
