In Tennessee, as in most U.S. states, the legal blood alcohol concentration (BAC) limit for drivers aged 21 and over is 0.08%.

Correct answer: Stop and wait until the lights stop flashing
When a school bus stops on a two-lane road with its red lights flashing, it signals that children are entering or exiting. Drivers in both directions are legally required to stop and remain stopped until the red lights are turned off and the bus begins to move. This law is paramount for ensuring the safety of children crossing the road.

In Tennessee, the default speed limit in a residential area is 25 mph, unless a different speed is clearly posted. This lower speed limit is set to increase safety for pedestrians, children, and other residents in areas with higher population density. Drivers should always be attentive to posted signs, but this is the general rule.

Early signaling is a fundamental practice for preventing collisions and maintaining smooth traffic flow.
