Final answer:
The 2 second rule is a minimum safe following distance, but when following a bus, it's safer to allow more than 2 seconds due to the bus's larger size and longer stopping distance.
Step-by-step explanation:
The 2 second rule is a guideline for drivers to ensure a safe following distance from the vehicle ahead. The rule states that a driver should stay at least two seconds behind any vehicle that is directly in front of the driver's vehicle. It is a way to measure the distance that provides enough time for the driver to react and avoid potential collisions.
When following a bus, however, it's often advised to increase this time due to a bus's larger size and potentially longer stopping distance. If a bus were to stop suddenly, following the 2 second rule might not provide sufficient time for the following vehicle to stop safely, especially in poor weather conditions or where visibility is limited. Therefore, while the 2 second rule is a minimum guideline, it's safest to allow an even greater following distance when behind a bus or a large vehicle.
So, to answer the question, the statement 'You should use the 2 second rule when following a bus' would generally be considered FALSE. It's better to use a longer following distance for safety reasons.
