The weather certainly doesn't make it feel like 'back-to-school' but today is indeed the first day of classes for the Plano, Kennedale, Venus, and Garland ISDs. So that means beware of school zones. Fines for speeding in a school zone start with the base fine of $127.10, an additional $8 per mile over the speed limit, and a $97.10 court cost. Yikers!
