A 3-minute lesson from the Kansas course. Read the rules and examples, follow the handbook page references, and check your understanding before you move on.
Kansas measures impairment by blood alcohol concentration, and by getting a license you've already agreed to be tested. Penalties apply to drug-impaired driving too, including prescription and over-the-counter medicines.
Blood alcohol concentration (BAC)
The percentage of alcohol in relation to the amount of blood in your body, usually measured by a breath, blood or urine test.
At .08 or more, your license may be suspended for 30 days and you may face criminal penalties. Even under .08 you are impaired and can still be convicted of impaired driving.
By getting a license you have consented to a lawfully requested test of your blood, breath, urine or other bodily substance if suspected of impaired driving.
Check the label before taking any drug, and ask your doctor or pharmacist if you're unsure about side effects. It is against the law to purchase, possess or consume illegal drugs.
A 19-year-old has one beer and drives. Their BAC tests at .03, under the .08 adult limit, but Kansas can arrest drivers under 21 at .02. They are in violation.
Check your understanding
Read the question, decide on an answer, then open it to check the explanation. These are Roadwise study questions based on the source handbook.
At what blood alcohol concentration (BAC) is a driver 21 or older in violation of Kansas law?
0.05% or higher
0.02% or higher
0.08% or higher
0.10% or higher
Answer: 0.08% or higher
Kansas law sets 0.08% BAC as the threshold for a per se violation for drivers 21 and older.
Under Kansas's implied consent law, getting a driver's license means you have agreed to:
Allow a search of your vehicle
Pay any traffic ticket without a hearing
Take a lawfully requested alcohol/drug test
Carry proof of insurance at all times
Answer: Take a lawfully requested alcohol/drug test
Implied consent means that by getting a license you have consented to a lawfully requested test of your blood, breath, urine or other bodily substance if suspected of impaired driving.
