Two Beers, a Sedating Antihistamine, and a Phone
You are at a family gathering in Paynesville. You drank two bottles of beer over three hours and ate a full meal. You also took a prescription antihistamine this morning that warns it may cause drowsiness. It is now 10:30 p.m. and you feel alert enough to drive. Your cousin asks you to drive her home 20 minutes away, then asks you to read a text message with the directions while you drive. On the way, a police checkpoint appears ahead. You have your license and vehicle papers, but you are not sure whether the beer or medicine is still affecting you. Your cousin says everyone does it, the road is mostly straight, and you have not slept well for two nights.
1. Should you drive at all? Explain how the beer, the antihistamine, fatigue, and the checkpoint fit into the decision.

No. The question is not whether you feel alert; it is whether your judgment, reaction time, and attention are unimpaired. Two beers over three hours may leave a low alcohol level, but the sedating antihistamine and two nights of poor sleep stack on top of it. Sedating medicines can cause drowsiness even when the label warning was hours ago, and alcohol plus a sedative is worse than either alone. The checkpoint is irrelevant to the safety decision; it only adds a consequence. If you would not drive with a child in the car, do not drive your cousin home. Call a sober driver, wait longer only if you are sure no sedating medicine is active, or let someone else drive. Feeling fine is not evidence.
2. Your cousin asks you to read the text message while driving. What should you do, and why is a quick glance not safe?
Read the worked answer
Do not read it while moving. Ask your cousin to read the directions aloud, or pull over in a safe place and read it yourself. A quick glance is not quick in terms of distance: at 30 mph, five seconds of eyes-off-road travel covers about 67 meters, and at night on a straight road that can be enough to miss a stopped truck, a pedestrian, or a pothole. The risk is not just the glance; it is the mental distraction that continues after you look up. If your cousin insists, tell her the phone stays down until you stop. You are the driver, so you set the rule.
3. How should you respond to your cousin's argument that everyone does it?

Answer with the specific risk, not a lecture. Everyone does it is a statement about popularity, not about stopping distance, reaction time, or crash outcomes. In this case you already have three risk multipliers: alcohol, a sedating medicine, and poor sleep. Adding a phone task makes four. Say clearly that you are not driving while impaired and not reading the phone, and offer a practical alternative: she reads the directions, you call a sober friend, or you wait. If she keeps pushing, do not argue at the wheel; park the vehicle and continue the conversation after you are both safe. Being firm now is cheaper than a collision.
