Advice needed for a weekend trip

I will be visiting jaipur during the weekend of 21st December and will be staying there for 3 nights. I have heard about multiple instances of jaipur traffic police not very tourist friendly (e.g. getting challan for minor violations when other local cabs and cars around are roaming freely. So it would be really helpful if you guys can share any tips to avoid getting any unnecessary trouble and fine during my visit to this beautiful city!
