Final answer:
When the lights are flashing at a railroad crossing, it is important to stop at a safe distance before the light post/gate. The appropriate stopping distance can vary depending on several factors, such as the speed of the vehicle, road conditions, and driver reaction time. It is recommended to leave a safe distance that allows the car to come to a complete stop before the railroad crossing, ensuring the safety of both the driver and any approaching trains.
Step-by-step explanation:
In the given scenario, when the lights are flashing at a railroad crossing, it is important to stop at a safe distance before the light post/gate. The appropriate stopping distance can vary depending on several factors, such as the speed of the vehicle, road conditions, and driver reaction time.
An example to understand stopping distance is given where a car initially traveling at 30.0 m/s is shown to have a total stopping distance on dry pavement with a 0.500 s reaction time.
It is recommended to leave a safe distance that allows the car to come to a complete stop before the railroad crossing, ensuring the safety of both the driver and any approaching trains.
