Rahul,
Just reiterating all the comments from the previous posts and few of my own experiences.
You need to understand that there are two components when your car changes states.
1)
Reregistering meaning your TN reg no will become AP, to do this you need NOC frm TN and Road Tax paid from AP. I can can live without reregistering for 1 year ( As per the previous threads)
2)
Road tax payment, you need to pay this amount in AP within one month of the car arrival, typically in the range of 5 to 10% of the invoice value depending on the age. However the arrival date is dicey as the cops cannot determine the exact date. If you are caught on camera on any offence (jumping signal's etc) or if you are pulled up the second time then there is a conclusive evicence of your arrival date. Your Reg is not affected.
The traffic cops generally do not pull you up for regn/road tax issues but the RTA guys do.
Since the RTA guys are only concerned about the road tax read that as revenue targets you can get away even if you have your car run on TN regn plates even after 1 year
Hope this brings things into perpective.
Now let me try to address you concerns on Cops(RTA) pulling you up.
Firstly their prime target is cars but they do pull up two wheelers as well.
And yes, as people have mentioned, Hitech city is a easy picking for the RTA guys and they do frequent this hot spot
To give you better understanding of the modus operandi
.
Hitech city is manned by Law and order cops and they have put up barricades on virtually all entrances to Hitec city
(a) new ring road
(b) Durgam Chervu
(c) Satyam office
(d) cyber towers
That leaves you no room to get in on any alternate route, so the RTA chaps just have to stand near these barricades to pull up out of state vehicle and the frequency with which they do these checks is on a quarterly basis which covers all the spectrum of the day and all the entry points.
How they do it
They stand in different entry points at different time in the day.
What do they ask,
1) First they verify their records/database which gives them info on if this vehicle was seen in Hyd earlier. (Eg cctv camera, their database of vehicle numbers pulled up earlier). You will have to believe me on this, as I do not have info on how they get this data. I was pulled up and shown the info through a hand held device. But generally they are lazy and do not do this at the first pass, only when you argue they try to pull up records
2) They ask you for your RC book to determine whose name is vehicle is in, logic is if its in your name you will have the vehicle here and also to check if any NOC is stamped.
3) Insurance and Pollution certificates, both indicate the city in which this was done, incase you have done this in Hyd then they ask no further questions but write a challan
To be honest I have driven on different KA regn cars for the last four years and have been pulled up about 10 times but the saving grace is, I keep travelling to Bangalore quite frequently technically the car has not been here for more than a month at the time of these checks. And I prove this by recent petrol bill, insurance and Toll tickets on the NH7, Service center bills etc
Send a mail in case you need further help
@ Pulsar56 I have been pulled up in all entry points, yes I partially agree with you on the Saty am route, i have not seen the RTA guys very active there, but as luck would have it i have been pulled up here as well, in one of the rare ocassion that I had used this route.
