Final answer:
The two-second rule for following at a safe distance holds true at any speed, as it is adaptable to various driving conditions, ensuring enough distance to stop safely.
Step-by-step explanation:
The two-second rule is a guideline that suggests a driver should stay at least two seconds behind any vehicle that is directly in front of the driver's vehicle. This rule helps drivers maintain a safe following distance at any speed and is adaptable to various traffic and weather conditions. While the two-second rule is generally effective at helping drivers maintain a safe distance from the car in front, it's important to note that in certain conditions, such as rain or icy roads, more distance may be necessary to stop safely.
