What law applies if you refuse to take an alcohol sobriety test when pulled over for weaving?

The implied consent law is the correct choice because it establishes that anyone who operates a motor vehicle on public roads implicitly agrees to submit to a sobriety test if asked by law enforcement. This means that by driving, individuals are considered to have consented to provide a breath, blood, or urine sample when there is reasonable suspicion of intoxication. Refusing to take the test can lead to legal consequences such as automatic license suspension and fines, even if they are ultimately not found guilty of driving under the influence.

The other options do not apply in this context. The zero tolerance law typically relates to underage drinking and driving, which would not be the primary focus if a driver over the legal drinking age refuses a sobriety test. Mandatory reporting laws pertain to obligations to report certain incidents or findings, which is unrelated to sobriety testing. The license suspension law may be a consequence of refusing the sobriety test, but it's not the primary legal principle that governs the situation; the key issue is the implied consent.
