How the exam asks it

About Medicines, drugs and the yellow sticker: which statement is WRONG?

  1. The standard is 'knows or ought to know that use can impair driving ability', not 'has a sticker'.
  2. The law explicitly names any substance you know or ought to know can impair driving ability — that includes prescribed medicines just as much as illegal drugs, exactly why the yellow sticker appears on legal, pharmacy-obtained medication.
  3. For combined use, each substance's limit becomes the lowest measurable amount: a zero-limit, lower than for single use.
  4. A medicine you take only once is completely out of your system again after a few hours.

Correct answer: A medicine you take only once is completely out of your system again after a few hours.

Some medicines remain active in the body for up to 48 hours, even after a single use. 'Taken once' says nothing about how long driving ability stays affected

Why learners get this wrong: If there is no yellow sticker on the packaging, you may drive without any restriction on that medicine.

Open this question

In Deventer you pick up a new sleeping medicine from the pharmacy. No yellow sticker visible, but the package insert lists drowsiness as a side effect. You use the medicine once, in the evening. The next morning at eight you drive to work. What applies?

  1. The insert lists drowsiness as a side effect; you know or ought to know your driving ability may be impaired, sticker or not
  2. Because you only used the medicine once, it is certainly out of your system by the next morning
  3. Without a sticker on the packaging you may drive without restriction
Show the answer

Correct answer: The insert lists drowsiness as a side effect; you know or ought to know your driving ability may be impaired, sticker or not

The standard is 'knows or ought to know' (the law), not the presence of a sticker.

Why learners get this wrong: A medicine you take only once is completely out of your system again after a few hours.

Correct answer: True

The standard is 'knows or ought to know that use can impair driving ability', not 'has a sticker'. The sticker makes that standard visible but is not a requirement for liability

Why learners get this wrong: If there is no yellow sticker on the packaging, you may drive without any restriction on that medicine.

Open this question

At the pharmacy in Deventer you buy painkillers. There is no yellow sticker on the box, but the leaflet says they can make you drowsy. You take one and then want to drive home. What do you do?

  1. You just drive: without a yellow sticker the medicine is safe
  2. You do not drive as long as the medicine can make you drowsy
  3. You wait a few hours; one pill will be out of your body by then
Show the answer

Correct answer: You do not drive as long as the medicine can make you drowsy

False — you think one pill is out of your body after a few hours. Some medicines keep working for up to 48 hours, even if you take them only once. You drive again only when the medicine can no longer make you drowsy

Why learners get this wrong: If there is no yellow sticker on the packaging, you may drive without any restriction on that medicine.
