I got a traffic challan from the police in December 2013, payable at the DTO office. I haven’t paid it yet. I was driving my friend’s car and he’s now refusing to pay. Could I face legal trouble or court issues in the future? It’s been over a year and I haven’t received any notices.

Yes, you could face legal trouble. The challan remains valid even if you haven’t received any notices. You are legally responsible for the challan, as you were driving the car. The court can issue a warrant for your arrest and impose penalties, including fines and imprisonment. It is advisable to resolve the matter as soon as possible.
