Traffic　signs　provide　drivers　with　essential　information.　It　is　important　for　drivers　to　recognize　and　make　a　response　based　on　the　messages　of　traffic　signs.　Although　several　studies　have　evaluated　the　legibility　of　different　kinds　(e.g.　color,　shape,　size)　of　traffic　signs,　there　are　very　few　studies　related　to　the　effect　of　driving　experience　on　legibility　of　traffic　signs.　This　study　was　conducted　to　find　the　variability　of　driver　eye　movements　with　different　driving　experience.　Eye　Tracking　System　was　used　to　study　characteristics　of　drivers＇　eye　movements,　such　as　fixation　duration,　variations　of　fixation　points　and　the　distribution　of　glance　zone.　Two　types　of　drivers　(experienced　and　inexperienced　drivers)　were　compared.　It　is　found　from　this　study　that　the　driving　experience　has　an　obvious　effect　on　the　characteristics　of　drivers＇　eye　movement.　Eye　movement　analysis　indicates　that　inexperienced　drivers　who　aren＇t　familiar　with　road　environments　look　at　the　signs　more　frequently　and　longer　than　experienced　drivers.　The　results　from　this　study　also　show　that　information　of　traffic　signs　should　not　be　excessive.　In　addition　traffic　signs　should　be　installed　in　proper　locations　to　tailor　to　driver　expectations.　The　findings　from　this　study　will　assist　traffic　engineers　in　designing　and　installing　the　traffic　signs　in　a　reasonable　way.
