The decision is not limited to the person behind the wheel. A scenario may place you as the driver, the person controlling access to the vehicle, or the person asking for transport. Name the role first, then apply the rule for that role without replacing it with guesses about distance, road type or confidence.
Use the role-risk-action method
Start with role: who would drive, who could supply the vehicle, and who wants the ride? Next identify the stated alcohol risk. The notice includes a driver who is still affected the next morning by a hangover, not only a person seen drinking moments before departure. Finally choose the preventive action for each role. The driver does not drive; the person with control of the vehicle keeps it unavailable to someone at risk; the would-be passenger does not ask a drinking person to drive and arranges other transport.
| Role in the decision | Required boundary |
|---|---|
| Driver | Do not drive while alcohol is still affecting you, including during a hangover |
| Vehicle provider | Do not make the vehicle available to a person at risk of alcohol-impaired driving |
| Ride requester | Do not knowingly ask a driver who has been drinking to provide the ride |
Keep the three checks separate even when one group is making the plan together. A sober person can still enable the prohibited drive by supplying the vehicle. A person who never touches the controls can still take part by knowingly requesting the ride. The notice warns that providing the vehicle or requesting the ride can also bring heavy penalties. This is why a safe plan changes the driver or the transport arrangement, rather than merely changing how the risky trip would be made.
Do not invent a shortcut for uncertainty
The scenarios give the relevant condition directly: the person has been drinking, may drive while affected, or remains hungover. Do not manufacture a waiting time, a road restriction or a test of apparent concentration that the notice does not provide. Feeling fine, promising to be careful or choosing a short journey does not establish that the stated risk has ended. Apply the role boundary to the facts you are given.
Common traps
- Treating coffee, slow driving, light traffic or local streets as a cure for a hangover. Those changes do not remove the stated alcohol effect.
- Requesting the ride after thirty minutes, from the rear seat or along quieter roads. None of those details shows that the drinking-related risk has ended.
- Assuming only the driver can face penalties because the requester does not operate the vehicle, or that a short trip or absence of a collision protects the requester. The requesting role is separately covered.
- Assuming the provider's responsibility exists only while riding in the vehicle or only after a collision. Knowingly making the vehicle available is itself the relevant act.
Try it
A friend who has been drinking asks to borrow your car. Which response follows the notice?
- Lend the car but follow behind in another vehicle.
- Refuse to provide the car to that person.
- Lend the car after receiving a promise to drive slowly.
- Allow the loan only when the planned trip is short.
A group is deciding how to get home after one member has been drinking. Which actions follow the notice? Select all that apply.
- Let the person drive because the trip is short.
- Keep the vehicle unavailable to the person at risk.
- Request a ride after the person says they feel fine.
- Arrange travel with a driver who has not been drinking.
