DKT Car Driver Knowledge Test – Alcohol and Drugs 1 — Questions and Answers

Question 1: Alcohol is a depressant. This means:

It makes you calm down and think more clearly.
It speeds your brain up so you can work better.
It slows down how quickly your brain works. (Correct answer)

Correct answer: It slows down how quickly your brain works.

As a depressant, alcohol affects the central nervous system, slowing down brain activity. This impairment leads to reduced reaction times, poorer judgment, decreased coordination, and difficulty processing information. These effects make driving extremely dangerous, as a driver's ability to respond quickly and accurately to road conditions is severely compromised.

Question 2: Before driving a motor vehicle or riding a motor cycle it is safest:

Drink 1 middy (285 ml) of light (low alcohol) beer.
Not to drink any alcohol. (Correct answer)
Drink 1 nip of spirits (30 ml or 1 oz).

Correct answer: Not to drink any alcohol.

The safest approach before driving or riding is to consume no alcohol at all. Even small amounts of alcohol can impair judgment, reaction time, and coordination, increasing the risk of an accident. Avoiding alcohol entirely ensures you are at your best to operate a vehicle safely and responsibly, minimizing any potential impairment.

Question 3: Having 1 or 2 alcoholic drinks before driving:

Has no effect on your driving ability.
Improves your driving ability.
Will affect your reactions and judgement. (Correct answer)

Correct answer: Will affect your reactions and judgement.

Even one or two alcoholic drinks can significantly impair critical driving abilities. Alcohol slows down your reaction time, making it harder to respond quickly to hazards, and it negatively affects your judgment, leading to poor decision-making. These impairments significantly increase the risk of a crash, even if you feel unaffected.

Question 4: If you are taking any sort of medicine, you should:

Only drive a motor car not a heavy vehicle.
Find out from your doctor or chemist whether the medicine or drug will affect your driving and act accordingly. (Correct answer)
Only drive during the day after taking the medicine or drug.

Correct answer: Find out from your doctor or chemist whether the medicine or drug will affect your driving and act accordingly.

Many medicines, both prescription and over-the-counter, can cause side effects like drowsiness, dizziness, or impaired concentration, which are dangerous for driving. It is crucial to consult a medical professional or pharmacist to understand potential impacts on your driving ability and follow their advice. This ensures you are aware of any risks and can act accordingly to ensure safety.

Question 5: What is the safest way to stay under the legal alcohol limit?

Exercising and drinking black coffee.
Buying a breathalyser (alcohol measuring instrument).
Not drinking any alcohol. (Correct answer)

Correct answer: Not drinking any alcohol.

The only guaranteed way to stay under the legal alcohol limit and ensure you are not impaired for driving is to avoid consuming any alcohol. The rate at which alcohol leaves your system cannot be sped up by exercising or drinking coffee. Not drinking at all eliminates any risk of exceeding the limit or being impaired.

Question 6: On Thursday, Friday and Saturday nights, how many serious crashes involve alcohol?

About 50%. (Correct answer)
About 30%.
About 10%.

Correct answer: About 50%.

Statistics consistently show that a significant proportion, about 50%, of serious crashes, particularly during peak social times like Thursday, Friday, and Saturday nights, involve alcohol. This high percentage underscores the severe danger and prevalence of impaired driving during these periods. It highlights the critical need for drivers to avoid alcohol before getting behind the wheel.

Question 7: Is it an offence to refuse to take a POLICE breath test?

No, if you are a learner driver.
No, if you say you haven't been drinking alcohol.
Yes, always. (Correct answer)

Correct answer: Yes, always.

In most jurisdictions, refusing a police breath test is a serious offense, regardless of whether you have been drinking or your license type. This refusal often carries penalties as severe as, or even more severe than, those for driving under the influence. It obstructs law enforcement's ability to enforce drink-driving laws and ensure road safety.

Question 8: If you hold a learner or provisional licence class what is the Blood Alcohol Concentration (BAC) limit?

Zero. (Correct answer)
0.02.
0.05.

Correct answer: Zero.

For learner and provisional license holders, a zero Blood Alcohol Concentration (BAC) limit is typically enforced. This strict limit acknowledges that new drivers have less experience and are more susceptible to the impairing effects of alcohol, aiming to minimize risk during their early driving years. Any alcohol consumption is prohibited for these drivers.

Question 9: If you are affected by a legal drug, such as a medicine (e.g. cold or allergy tablets)

You may drive only in daylight hours.
You must have a passenger to help you drive.
You must not drive. (Correct answer)

Correct answer: You must not drive.

If you are affected by any drug, legal or illegal, that impairs your ability to drive safely, you must not get behind the wheel. Even legal medications can cause drowsiness, dizziness, or reduced concentration, making driving dangerous and illegal if your faculties are compromised. Your ability to operate a vehicle safely is paramount.

Question 10: To reduce the effect of alcohol before driving or riding you should:

Wait. The time depends on how much you have drunk. (Correct answer)
Drink black coffee.
Have a glass of water.

Correct answer: Wait. The time depends on how much you have drunk.

The only effective way to reduce the effect of alcohol in your system is to allow time for your liver to metabolize it. The rate of alcohol elimination is relatively constant, and factors like coffee or water do not speed up this process. The waiting time required depends entirely on the quantity of alcohol consumed, so patience is key.

Question 11: If you take medicine and then drink alcohol:

It can have a particularly bad effect on your driving ability. (Correct answer)
The alcohol will have less effect than if taken alone.
Your ability to react to emergencies will improve.

Correct answer: It can have a particularly bad effect on your driving ability.

Combining alcohol with medicine, even over-the-counter drugs, can lead to unpredictable and often intensified side effects. This interaction can severely impair your judgment, coordination, and reaction time, making driving extremely dangerous and significantly increasing the risk of a crash. Always consult a doctor or pharmacist about potential interactions before driving.

Question 12: When drivers have been drinking, the crashes they are involved in are generally:

About the same.
Less serious.
More serious. (Correct answer)

Correct answer: More serious.

Crashes involving drivers who have been drinking are generally more serious due to impaired judgment, slower reaction times, and increased risk-taking behavior. Alcohol-impaired drivers are less likely to react effectively to hazards, often leading to higher impact speeds and more severe injuries or fatalities. The impairment prevents them from making safe decisions or reacting appropriately.

Question 13: If you have used illegal drugs you:

Must not drive. (Correct answer)
May drive only in light traffic.
Should drink coffee before driving.

Correct answer: Must not drive.

Using illegal drugs severely impairs your cognitive and motor skills, including judgment, reaction time, perception, and coordination. Driving under the influence of illegal drugs is extremely dangerous and illegal, as it significantly increases the risk of causing a serious accident. Your ability to safely operate a vehicle is compromised, making it a severe hazard.

Question 14: You want to drive your car but you have a very bad headache. A friend gives you some of their headache tablets to kill the pain. What should you do before you take these tablets?

Read the label and confirm they are not prescription drugs and there are no special warnings on the label. (Correct answer)
Ask your friend if the tablets have affected them.
Drink a large glass of milk because this reduces the adverse effects of medicines and drugs.

Correct answer: Read the label and confirm they are not prescription drugs and there are no special warnings on the label.

Before taking any medication, especially one not prescribed to you, it is crucial to read the label carefully. This ensures you understand potential side effects, dosage, and any warnings, particularly those related to driving or operating machinery. Taking unknown medication without this information can be dangerous, as it might impair your ability to drive safely.

Question 15: If you are taking several medications and you want to drive, you should:

Ask your passengers to let you know if you are not driving as well as you should.
Ask your doctor if the combination of drugs will make it dangerous to drive. (Correct answer)
Drive carefully around your local streets to see if you are affected.

Correct answer: Ask your doctor if the combination of drugs will make it dangerous to drive.

When taking multiple medications, there's a risk of adverse drug interactions that can impair your driving ability. Only a doctor or pharmacist can accurately assess how a combination of drugs might affect your concentration, reaction time, or alertness. Consulting them ensures you receive professional advice on safe driving and avoid dangerous side effects.

Question 16: After drinking alcohol you could:

Be able to pay close attention to details in the traffic.
Be able to drive the same as you normally can.
Misjudge speed (your own and others). (Correct answer)

Correct answer: Misjudge speed (your own and others).

Alcohol impairs judgment, perception, and reaction time, all of which are critical for safe driving. Misjudging speed, both your own and other vehicles', is a direct consequence of this impairment. This significantly increases the risk of accidents because you cannot accurately assess distances or react appropriately to changing traffic conditions.

Question 17: Before taking any drugs and then driving it is most important to:

Have some food in your stomach.
Plan to have some other person with you.
Know what the effects of the drug are. (Correct answer)

Correct answer: Know what the effects of the drug are.

Before driving after taking any drug, it is paramount to understand its potential effects on your ability to operate a vehicle safely. Drugs can impair judgment, coordination, reaction time, and vision, even if they are prescribed or over-the-counter. Knowing these effects allows you to make an informed decision about whether it's safe to drive and avoid dangerous situations.

Question 18: If you are going out and going to drink alcohol, the best way to avoid having to drink and drive is to:

Wait for one hour after your last drink before you drive home.
Organise before hand a way of getting home where you are not the driver. (Correct answer)
After you have had a few drinks, start to think about how you will get home.

Correct answer: Organise before hand a way of getting home where you are not the driver.

The safest and most responsible way to avoid drunk driving is to plan for alternative transportation before you start consuming alcohol. This proactive approach ensures you have a designated driver, use public transport, or arrange a taxi/rideshare service. Waiting until after drinking to decide is risky, as your judgment will already be impaired, leading to potentially unsafe choices.

Question 19: Even if you feel unaffected after drinking alcohol, you should:

Be aware that your abilities are decreased. (Correct answer)
Drive, but avoid using freeways.
Spend more time than usual looking in the mirrors.

Correct answer: Be aware that your abilities are decreased.

Even if you don't feel the immediate effects of alcohol, your driving abilities are decreased from the first drink. Alcohol impairs judgment, reaction time, coordination, and vision, making it unsafe to drive. Acknowledging this decreased capability is essential for making responsible decisions and avoiding dangerous situations on the road, regardless of how you feel.

Question 20: If you are driving a bus, taxi, hire-car, heavy motor vehicle (over 13.9 tonnes Gross Vehicle Mass), or a vehicle with a dangerous load, it is an offence when the level of alcohol in your blood reaches:

0.08.
0.02. (Correct answer)
0.05.

Correct answer: 0.02.

For drivers operating specific vehicles such as buses, taxis, heavy motor vehicles, or those carrying dangerous loads, a much stricter blood alcohol concentration (BAC) limit of 0.02 is enforced. This lower limit reflects the higher responsibility and potential for severe consequences associated with operating these types of vehicles. It emphasizes maximum safety for both the driver and the public.
