Road signs are found next to the road. Some in­di­cate to road users what they may and may not do, and oth­ers pro­vide help­ful in­for­ma­tion. Road signs use sym­bols and let­ters that make them fast and easy to un­der­stand.

Reg­u­la­tory signs help reg­u­late the orderly flow of traf­fic. These signs are sub­di­vided into dif­fer­ent colours and shapes to make them in­stantly recog­nis­able: con­trol (eg stop signs) pro­hi­bi­tion (eg speed limit) com­mand (eg keep left) reser­va­tion (eg re­served lanes) Tem­po­rary traf­fic con­trol signs are signs on a yel­low back­ground and are tem­po­rar­ily put up where there are road­works. Warn­ing signs pro­vide in­for­ma­tion about po­ten­tial dan­gers road users might come across. Warn­ing signs come in the form of a red tri­an­gle, usu­ally with a black sym­bol on a white back­ground. In­for­ma­tion signs give road users use­ful in­for­ma­tion to make their jour­ney eas­ier. These are white on a green back­ground.

Guid­ing signs in­di­cate to road users where they are, how to get to cer­tain des­ti­na­tions and where the road they’re on leads. These are es­pe­cially use­ful for those who might not be fa­mil­iar with the area.
