i want to become a traffic police?what i want read please guide my question

in any police organisation, qualification is for certain category but even highest qualification is graduation from any university in aqny stream. Police dont recruit direct traffic Police rather those who are in police gets diverted to traffic police. Now the question is traffic police has 4 category of rank and 2 category of qualification. for constable min is 10th pass for other 3 category, U should be grad from anywhere . I m sure U r clear n most important is police is state affair so its a state recruitment thru traffic [police come. Wht is ur interest. R u impressed with their devotion or their earnings. all the best
