Final answer:
The rule of 3 second hesitation in driving ensures safety and reduces the risk of accidents by giving drivers time to assess the situation before proceeding.
Step-by-step explanation:
The rule of 3 second hesitation is often followed in driving to maintain safety and prevent accidents. It suggests that a driver should wait for at least 3 seconds before proceeding when a traffic light turns green or when a stopped vehicle in front starts moving. This allows time for the driver to assess the situation and ensure that it is safe to proceed.
By waiting for a few seconds, drivers can avoid potential collisions caused by other drivers running red lights or engaging in unexpected behavior. It also allows for any unexpected hazards to become apparent. It's important to note that the 3 second rule is a general guideline and may vary based on specific driving conditions and speed.
