Yesterday, my brother gave LL test (Learning License) and got failed (he scored 5/15). Today, he may again give retest. He is saying that he now knows more than when he gave his previous test. I fear he may again fail in test. I don't know how many days should he prepare well before giving retest. (That's an online test at home)
I heard from someone that it is possible to get license without any test by paying 3,000-4,000 rupees. Failing in all 3 attempts of test means never able to drive. I see a lot of illiterate people driving motorcycle. The law says that driving without any license means seizure of vehicle and test is compulsory for both learning and driving license. Without LL, you cannot get DL.
I don't think police officers really check your license. Maybe they check your license only when you break traffic rules. It is also possible that many people driving on roads are without any license.
