Which of the following is true about driving under the influence of drugs or alcohol?

Answer: B — It is illegal and dangerous

Driving under the influence of drugs or alcohol is not only illegal, but also very dangerous. It impairs a driver's judgement, coordination, and reaction time, increasing the risk of accidents. Choosing option A is incorrect because driving under the influence is never safer than driving without impairment. Option C is also incorrect because it is not a safe driving practice, but rather a dangerous and illegal one. Option D is incorrect because while some may falsely believe it helps improve reaction time, in reality it decreases coordination and slows down reaction time, making it a dangerous choice.
