Does Allstate offer international driving coverage in North America?

I have a 2021 Kia K5, and I’m considering adding a new exhaust. However, I'm worried it'll interfere with my warranty because it’s still covered for several more years. What voids the Kia new vehicle warranty?

After years of saving, I finally have enough for a down payment on a Chevrolet Corvette. Since it’s relatively complex under the hood, I just want to know what the warranty is and what it covers. What is included in the Chevy Corvette warranty?

My mom is always telling me to be on the lookout for red light cameras so that I don’t get ticketed. She said that the cameras are sometimes covert and won’t flash when you run the light to catch you unaware. My question is, do the cameras on a red light always flash?
