Final answer:
Both a) and b) are true in the Iowa Implied Consent Law, meaning drivers arrested under suspicion of DUI may be asked to undergo a chemical test, and refusal leads to suspension of driving privileges.
Step-by-step explanation:
According to the Iowa Implied Consent Law, which applies to both resident and nonresident drivers, there are two primary assertions:
- An arrested driver may be asked to submit to a chemical test to determine the alcohol content in their blood.
- Refusal to submit to chemical testing will result in the driver's driving privileges being withdrawn.
Both statements a) and b) are true under this law. When a driver is pulled over on suspicion of driving under the influence (DUI), law enforcement can request a Breathalyzer test, which measures ethanol concentration in the individual's breath.
This breath test is indicative of the driver's blood alcohol concentration (BAC). BAC is affected by factors such as age, sex, and overall health. Consequently, refusing the Breathalyzer or other chemical tests can lead to immediate penalties, including the suspension of driving privileges.
It's important to note that alcohol affects one's ability to perform tasks that require skill and judgment, and the cerebellum, which is critical for coordinated movements, is particularly sensitive to ethanol. These factors are the basis for field sobriety tests and Breathalyzer tests to ensure driver safety and adherence to legal standards.
