What is the primary instruction for drivers under sedatives or hazardous drugs?

The primary instruction for drivers under sedatives or hazardous drugs is to avoid driving altogether. This is because these substances can impair a person's ability to operate a vehicle safely. Sedatives can cause drowsiness, decreased alertness, and impaired coordination, while hazardous drugs may affect cognitive functions and reaction times. Even if a person feels fine or believes they can drive safely, the risk of impaired judgment and reaction time is significant. The safest choice is to refrain from driving until one is certain that the effects of the substances have worn off and they are fully alert and able. This not only ensures the safety of the driver but also the safety of other road users.
