prescription medication is legal, which means you can drive after taking any prescription medication.

It is not automatically legal to drive after taking any prescription medication. The legality depends on whether the medication affects your ability to drive safely. If your driving is not impaired and you are taking the medication exactly as prescribed, then you are not breaking the law. However, it is illegal to drive if your ability to drive is impaired by any drug, including prescribed medications. Many prescription medications, especially those affecting the nervous system such as benzodiazepines (e.g., diazepam, lorazepam), opioids (e.g., morphine), and others can impair driving ability. Laws often set specific drug levels in the blood above which it is illegal to drive, but these limits are usually higher than therapeutic doses prescribed by doctors. Still, if you feel drowsy, dizzy, or otherwise impaired by your medication, you should not drive. The best practice is to consult your healthcare provider about whether your prescribed medication might affect your driving. Carrying evidence of the prescription and following dosage instructions helps, but impairment is the key factor legally. Driving while impaired—even on prescription medication—is an offense and can lead to prosecution. In summary, being prescribed medication does not automatically mean you can drive safely after taking it. You can drive legally only if your driving is not impaired and you follow your healthcare provider's advice and the medication instructions.
