Classification of road signs

Road traffic signs are signs set up on roads in most countries to warn, prohibit, restrict, and instruct road users. International road traffic signs originated in Europe in an attempt to break down the barriers caused by different languages and characters in different places.
The annex to the "Convention on Road Signs and Signals of November 8, 1968" before the revision divided road traffic signs into seven categories: hazard warning signs (except those located near intersections or level crossings), those that control the right of way at intersections Signs, danger warning signs on the approach roads of intersections and signs regulating the right of way in narrow sections Signs on level crossings Right of way, temporary parking and other prohibited signs other than parking signs Instructional signs other than parking signs Temporary parking and parking signs Additional signage Countries classify road traffic signs in different ways.
