Final answer:
Under good road conditions, the driver should maintain a safe following distance from the vehicle ahead to ensure safety and compliance with traffic laws.
Step-by-step explanation:
The appropriate measure to be used by the driver who is following a vehicle under good road conditions is maintaining a safe following distance. This ensures that the driver has enough time to react and stop if necessary to avoid a collision. Tailgating and honking are aggressive behaviors that can lead to road rage and are not safe driving practices. Overtaking should be done with caution and only when it is legal and safe to do so.
When driving under any conditions, including good ones, it is critical to prioritize safety and obey traffic laws to prevent accidents and ensure the well-being of all road users.
