Final answer:
The statement that the three-second rule helps determine a safe following distance for drivers is true. This rule creates a safer driving distance by considering the driver's reaction time and stopping distance under different road conditions.
Step-by-step explanation:
The statement, "The three-second rule helps the driver determine a safe following distance," is true. The three-second rule is a guideline that advises drivers to maintain a distance that takes at least three seconds to cover at their current speed from the vehicle in front of them. This rule accounts for the time needed for a driver to react and the additional distance required to safely stop the vehicle under various road conditions and driver reaction times. By applying this rule, drivers can adjust their following distance to create a safer driving environment and potentially avoid collisions, especially when driving at higher speeds or in less than ideal conditions.
For example, during dry conditions, the stopping distance for a car initially traveling at 30.0 m/s, with a 0.500 s reaction time, can be calculated and compared to the distance needed during wet conditions. The three-second rule provides a practical application of the relationship between speed and stopping distance we analyze in topics related to road safety.
The three-second rule is a concept used to determine a safe following distance while driving. It states that a driver should maintain a distance of at least three seconds behind the vehicle in front of them. This rule helps to ensure that there is enough time and space to react to any sudden changes or emergencies on the road.
For example, if the car in front of you passes a fixed object like a sign or a building, you should count how many seconds it takes for your car to reach that same object. If it's less than three seconds, you're following too closely and should increase the distance.
This rule is based on the principles of physics, specifically the relationship between speed, reaction time, and stopping distance. By maintaining a safe following distance, you give yourself enough time to react and stop your vehicle safely, reducing the risk of accidents.
