Lol. One road is typically more the primary road. When in doubt yield. It's been a long time since I went through the drivers Ed manual, but I taught my daughter and she's totaled 2 cars in the last 3 years by looking at the phone and not paying enough attention.

In the end I think all drivers should exercise caution and pay attention. A little common sense goes a long way. If only it was more common ha ha ha
