Dear aspirant,

If you have violated any traffic rule then the traffic police take pictures of your vehicle's number plate and then notes down your phone no. and address. After that an SMS is sent to your phone with a link in the message. Click on the link. The e-challan website will open. And then you can pay the challan. You are given 60 days to pay the challan. If you do not pay the challan then your challan can be taken to the court and if found guilty then you will have to  give additional fine.

Hope this helps
