This question has been touched on several times before.
But I live in VA. We're not required to notify the LEO. I've been pulled over 3 times since being issued my permit.
First time was actually in WV Harpers Ferry area. I did all the usual things, turn on the interior lights, keep hands on the wheel etc. Handed him DL, reg and CC permit. He seemed to relax after that and gave me a warning to slow down. I also had my friend and her daughter in the car which may have lowered his BP some.
Second time, in VA. Again, for mild speeding. Handed over the same stuff, officer handed back my permit saying, "I don't need this".
Third time, again...handed it back to me.
I just do it as a courtesy. They can pull up on their 'puter I have a permit, so it's pretty much moot.
The officers is approaching you with no background of who you are. He approaches you with the same suspicion as he would a drug dealer.
That's definitely not true in other parts of the country. Around here, it's a simple traffic stop. And guess what, some of these LEO's have actually been very nice and helpful. I had a problem with a car recently and had to pull over. LEO stopped, and we spent the next 10 minutes trying to figure out the issue. Turns out the e-brake was on, but he tried!
