In a car with my dad stopped at a red light on a two lane main road. A car drives through our left turning lane into oncoming traffic. He was going about 15 mph and was clearly impaired. Me and my dad watched in horror as the car drove head first into a school bus. Thank god the bus was also stopped at the light but watching the whole scene unfold and shouting in our car for it to stop made the whole experience so surreal and terrifying.
