Well first off I just want to say hi to everyone, I just signed up! But about my problem, whenever I activate my sirens in game the traffic will not pull over to the side when I'm near them. I recently DLed "NB's Mod Pack" from one of his preview videos. The pack contained siren sounds and I installed them using Spark IV, and it works fine in-game. Although the traffic does not seem to react to the sirens now. I was wondering if this is because of the new sounds or what? Any help is greatly appreciated, thanks.
