i just got my extract today from Sheikh Sarai RTO, Delhi. here are the steps i followed:
1. went to information desk, and asked for process- i had to explain what i need and she told me it was called an experience letter. asked me to take a written application for the same to the inspector
2. went to the inspector who informed me it was called 'Extract'. took a copy of the driving license and letter- signed the letter and asked me to submit fees.
3. waited for a long time for the fee submission. checked online, there is no option for paying this fee online. i will try the helpline.
4. after paying fees, went to data entry desk- they asked me to check details and go back to Inspector.
5. the inspector took a look at my fees and gave to his assistant.
6. assistant asked me to get printout from one of the other desks and the inspector signed/stamped it immediately.
the overall process is very smooth and transparent. no hassles or requests for bribe. inspector extremely polite and courteous. explained things to me even though there is a huge line. saw him behave well with others as well.
for those interested, you may see the redacted version of the extract here.
