Now that Dubai traffic is very busy i wish to understand each and every information you display on the sign board so that i will drive safely following the sign board. In a large Dubai sign board you see so many exit indication and so confusing us. Also at the top you see exit with some exit number. you find exit with arrow mark sometimes in blue and sometimes in white mark. Sometimes 2 exits with arrow and in   white colour. What does all this mean?/ Is there any book to refer?Pl let me know and thanks.
