The safe following distance in good conditions is measured in time, which is why the two to three seconds option is the correct choice. This method allows drivers to maintain a safe amount of space between their vehicle and the one in front, enabling enough time to react to any sudden stops or emergencies. By counting the seconds it takes to reach a stationary object after the vehicle in front passes it, drivers can ensure they have adequate distance to stop safely without rear-ending the car ahead.

The other options are not based on an adequate safety measure for maintaining a following distance. One car length may vary significantly depending on the speed of travel and does not account for a driver's reaction time. Five car lengths could be excessive for most driving situations and may lead to unnecessary gaps, potentially causing disruptions in traffic flow. One second is insufficient following distance, as it does not allow enough time to react to potential hazards on the road.
