When following another vehicle you are legally required to?

When following another vehicle, you are legally required to maintain a safe following distance to ensure you can stop safely if the vehicle in front of you suddenly slows down or stops. This distance can vary based on speed, road conditions, and weather, but a common rule of thumb is to stay at least two seconds behind the vehicle ahead. Additionally, you should avoid tailgating and remain alert to the actions of the vehicle in front of you. Always adhere to local traffic laws and regulations regarding following distances.
