1.2. he Motor Vehicles Act. 1988 has covered all the signs warranted b! differenttraffic sit"ations .he designs of signs are f"ll! di#ensioned. $"rther, the signshave "nifor#it!, and #ostl! s!#bols are "sed to conve! the #essage, especiall!in the case of reg"lator! signs.

Road )igns are classified "nder the following three heads

indicate re?"ire#ents, restrictions and prohibitions.hese incl"de signs, s"ch as, )B(, /IV* CAD,)peed =i#its, -o *ntr!, etc which give notice of rightof wa!, special obligations, prohibitions or restrictionswith which the road "sers #"st co#pl!. hese areinstalled to give effect to a traffic reg"lation order orother stat"tor! provision. Reg"lator! signs either givepositive instr"ctions or indicate a prohibition. )ignsgiving positive instr"ctions are generall! circ"lar with awhite border and s!#bol on a bl"e backgro"nd. he!"s"all! indicate so#ething all drivers #"st do 4e.g.

keep left5. he e&ceptions in shape are the octagonalred )B( sign and the triang"lar /IV* CAD sign.hese two signs provide indication abo"t the right ofwa! to drivers. (rohibitor! signs, which generall!indicate to the drivers what the! #"st not do, are#ostl! circ"lar and have a red border. he red ringindicates the prohibition+ diagonal bars are "sed onl! onsigns which prohibit a specific #anoe"vre, i.e. bannedleft or right t"rns or t"rns. hese signs need to beco#plied with and an! violation of the r"les andreg"lations conve!ed b! these signs is a legal offence.
