In the Malayalam movie 'How old are you?' Manju Warrier's character is a 35 years old house wife. In an important sequence, it is being said that her driving license got expired and she was not aware of that. In Kerala, AFAIK, driving licenses are not issued to minors below 18 years (which I believe will be similar in other Indian states, too). And the issued license will be valid for 20 years from the date of issue. So she should have got her license at 15 years of age for it to expire at 35.
Is this a mistake that they missed to correct, or are there any exceptions to normal motor vehicle rule that I did not notice?
In the movie, license is used to appear in a car hit-and-run case. So it cannot be a light motor bike license, which one can get at the completion of 16 years of age.
