RTO India — physically handicapped, not getting license

I am a physically handicapped person, aged 23. I have problems with right arm. But using my artificial hand, i am able to drive 2 wheelers and 4 wheelers without any modification. I can drive a normal vehicle and rtos are not allowing to issue license or even allowing to sit for the test. I can purely control the vehicle using my artificial hand. I tried to obtain license in kerala and bengaluru and met many rtos. I heard that these rules are only strict in india. India is a country where equality is there. But in these cases, we are facing many difficulties. My sincere request to the government, kindly allow us to show our driving skills and later decide whether to give license or not. Don't avoid us at the initial stage. Please please do something and issue normal license for us...
