Alcohol, Drugs & Distraction — Practice Test 2026

Not quiteCorrect answer: A — 0.04%

Commercial drivers are held to 0.04%, half the limit that applies to ordinary drivers.

Holding a commercial licence does not mean the ordinary 0.08% applies while driving your own car — a CDL holder faces consequences either way.

Not quiteCorrect answer: D — 0.08%

The limit is 0.08% for drivers 21 and over, 0.04% for commercial drivers, and 0.01% for anyone under 21 under the zero-tolerance law. You can still be arrested below these numbers if you are impaired.

Being under the limit is not a defence if your driving shows impairment.

Not quiteCorrect answer: D — Stopping somewhere safe and sleeping

Only sleep reverses fatigue. Cold air and caffeine buy minutes and mask how close you are to a microsleep.

Drowsy drivers routinely report feeling fine right up to the crash. Fatigue removes the ability to judge fatigue.

Not quiteCorrect answer: B — Their driving privilege is automatically suspended for six months

Florida's Zero Tolerance law suspends the driving privilege for six months at .02 or higher for anyone under 21. At .05 or higher they must also attend a substance abuse course.

The .08 figure is assumed to apply to everyone. For under-21 drivers the threshold is a quarter of it.

Not quiteCorrect answer: C — Attend a substance abuse course

At .05 or higher an under-21 driver must attend a substance abuse course. For drivers under 19, an evaluation is completed and the parents or guardians are notified of the results.

The consequences for a young driver escalate in steps rather than arriving all at once at .08.

Not quiteCorrect answer: D — 10 days from the date of arrest

You must apply for a formal or informal review hearing at the appropriate Bureau of Administrative Reviews office within 10 days of the arrest date.

The window is short and runs from arrest, not from conviction or from receiving paperwork.

Not quiteCorrect answer: D — 0.08 or more

The handbook states 0.08 or more for drivers over 21.

Being below the figure is not a defence if your driving is impaired; the offence is intoxication, and the number is one way of proving it.

Not quiteCorrect answer: C — Suspension of your driving privilege

The handbook lists refusal alongside failing the test as a ground for suspending the driving privilege, for any person.

Refusing feels like withholding evidence. The suspension follows from the refusal itself.

Not quiteCorrect answer: B — Their driving privilege is suspended — Texas has zero tolerance for minors

In Texas a minor is anyone under 21, and any detectable amount of alcohol triggers suspension. There is no threshold to stay under.

Other states set a small number such as 0.02. Texas uses "any detectable amount", which is a stricter standard than a figure.

Not quiteCorrect answer: D — Already agreed to take a chemical test if lawfully arrested for an alcohol or drug offence

Consent is given by the act of driving. It applies after a lawful arrest, not at random.

Implied consent is read as permitting stops without cause. It concerns testing after a lawful arrest.

Not quiteCorrect answer: C — 10 days from the date of arrest

The temporary licence issued at arrest lasts 30 days, but the window to request a hearing is only 10 days from the arrest.

The 30-day temporary licence is mistaken for the deadline. Missing the 10-day window forfeits the hearing.

Not quiteCorrect answer: A — .18 or more

Aggravated DWI applies at .18 percent or more, carrying heavier penalties than ordinary DWI.

Most states set the aggravated threshold at .15. New York sets it higher, at .18.

Not quiteCorrect answer: B — Six months

The handbook gives a minimum of six months for a .08% or higher result.

The suspension is administrative and begins independently of the criminal case.

Not quiteCorrect answer: D — Time

Only time lowers blood alcohol. Coffee and a cold shower may make someone feel more alert while leaving them just as impaired.

Feeling more awake is mistaken for being less impaired, which produces a driver who is alert enough to attempt the drive and impaired enough to crash.

Not quiteCorrect answer: D — DWAI — driving while ability impaired, a separate offence covering more than .05 up to .07

New York defines DWAI for BAC above .05 and up to .07. Only at .08 does it become DWI, and at .18 or more it becomes aggravated DWI.

The belief that .08 is a bright line below which nothing is an offence is wrong in New York.

Not quiteCorrect answer: A — Still a significant distraction, because the impairment is cognitive rather than manual

The measurable loss is in attention, not in hands. Drivers on hands-free calls look at hazards without registering them.

Hands-free laws are read as a safety endorsement. They address the manual part of the problem, which is the smaller part.

Not quiteCorrect answer: C — Prohibited until they turn 18, except in an emergency

The restriction covers any wireless communication device, hands-free included, until the driver reaches 18. Only an emergency is excepted.

Hands-free is widely read as the safe and legal option. For under-18 drivers in Texas it is neither.

Not quiteCorrect answer: A — An automatic licence suspension, in addition to any DUI penalty

By holding a California licence you have already consented to chemical testing if lawfully arrested for DUI. Refusing triggers a licence suspension on its own, separately from whatever the DUI case produces.

Refusing does not avoid punishment — it adds a penalty that applies even if the DUI charge fails.

Not quiteCorrect answer: A — Illegal — adult drivers may only use a phone hands-free

Handheld use is prohibited outright. The handbook adds that you should not answer a ringing phone at all, and should pull off the road to make a call.

Being stopped in traffic is not being parked. The prohibition applies while you are driving, including at a red light.

Not quiteCorrect answer: A — By being licensed to drive in Pennsylvania

The consent is a condition of the licence itself, and applies once police arrest you for driving under the influence.

Drivers believe they can decline because they never signed anything. The licence was the signature.

Not quiteCorrect answer: C — 0.08% or higher

California sets 0.08% for drivers 21 and over. You can still be arrested below that figure if your driving is impaired.

The legal limit is not a safe limit. Impairment is measurable well before 0.08%.

Not quiteCorrect answer: A — Not at all, even hands-free, except in an emergency

Drivers under 18 may not use a mobile phone at all while driving, including hands-free, except to call for emergency help. Drivers 18 and over may use a phone hands-free only.

Hands-free is allowed for adults but not for drivers under 18 — the rules are different by age.

Not quiteCorrect answer: C — .02

Under-21 drivers are considered to be driving under the influence at .02 or more.

California sets .01 and Pennsylvania .02. Carrying the wrong figure across state lines is a common error.

Not quiteCorrect answer: B — Between two and seven times more likely to crash than drivers with no alcohol

The manual gives this figure explicitly, to counter the belief that only heavy drinking is risky.

"Only had a couple" is measured against the legal limit rather than against sober. The risk curve starts rising long before .08.

Not quiteCorrect answer: D — 0.01%

California's zero-tolerance limit for under-21 drivers is 0.01%. The same 0.01% limit applies to any driver of any age who is on DUI probation.

Many states use 0.02%. California is stricter, and 0.01% is low enough to be reached by cough medicine.
