How does tailgating affect safe driving practices?

Tailgating significantly reduces reaction time, which is crucial for safe driving. When a vehicle follows closely behind another, the driver has less time to respond to sudden stops or changes in traffic conditions. This diminished reaction time can lead to collisions, as the following driver is unable to stop safely or maneuver out of the way if the vehicle ahead unexpectedly slows down or halts. Maintaining a safe following distance is essential for allowing adequate time to react, ensuring both the driver's safety and the safety of others on the road.
