What Are Mandatory Traffic Signs (Blue)?
Mandatory traffic signs use a blue background and white symbols to indicate instructions that drivers must obey. These are the most important traffic signs for safe and legal driving.
Mandatory signs are blue with white symbols and command drivers to follow specific routes or lanes: directional arrows (→), one-way roads, keep-right, designated pedestrian/bicycle paths, and bus lanes. Violating them risks fines and accidents.
