Two Beers, a Checkpoint, and a Refusal
At 11:40 p.m. on a Friday, a 20-year-old driver leaves a friend's house in Las Cruces after drinking two 12-ounce beers between 9:00 and 10:30 p.m. He has eaten dinner. He drives a compact car with one passenger, age 19. A sobriety checkpoint is set up on a city street; an officer smells alcohol, notes bloodshot eyes and slurred speech, and asks him to step out. The driver admits to "a couple of beers" and agrees to field sobriety tests, which show clues. At the station he is asked for a breath sample and refuses. A records check shows no prior offenses. His license is from New Mexico. He asks whether refusing was smart and whether he is "under the limit" because he only had two beers.
1. He believes he is legal because he had only two beers. What alcohol limit actually applies to him, and does the number of drinks settle the question?
Read the worked answer
The 0.08 figure does not apply to him. New Mexico sets a 0.02 BAC limit for drivers under 21, so he is over the limit at a far lower concentration than an adult. Two 12-ounce beers in 90 minutes can exceed 0.02 for a 20-year-old depending on body weight, food, and timing, so his own count of drinks proves nothing.
More importantly, DWI in New Mexico can be proven by impaired driving, not only by a number. The officer already has slurred speech, bloodshot eyes, an admission of drinking, and clues on the field sobriety tests. Those observations support a DWI charge even if a chemical test came back below 0.08. His age adds a separate zero-tolerance administrative revocation on top of any criminal charge.
2. What are the legal consequences of refusing the breath test, and how does the refusal change the case against him?
Read the worked answer
New Mexico's implied consent law means that by driving on its roads he already agreed to chemical testing after a lawful arrest. Refusing is not a safe loophole.
- Administrative: refusal triggers revocation of his driving privilege, typically for one year for a first refusal, through a separate civil process.
- Criminal: refusal to submit is one of the statutory grounds that can elevate a DWI to aggravated DWI in New Mexico, alongside a BAC of 0.16 or more or causing injury. So refusing can make his charge more serious, not less.
- Evidence: the refusal can be presented to the judge or jury, and prosecutors often argue it shows awareness of guilt.
His reasoning error is treating refusal as a way to erase the evidence. The officer's observations and the admitted drinking remain, and the refusal itself becomes a fact used against him.
3. If he had blown 0.16 instead of refusing, how would the charge and consequences differ from a plain first offense?
Read the worked answer
A result of 0.16 or higher crosses New Mexico's aggravated DWI threshold. The core offense is still DWI, but the classification changes, and with it the exposure:
- Enhanced penalties compared with a simple first offense, including a higher likelihood of jail time and greater fines.
- Ignition interlock requirements and mandatory screening/treatment obligations are more demanding.
- The high reading also undercuts any argument that he was merely tired or that the test was borderline.
Note that he reaches aggravated DWI either way here: a 0.16 reading and a refusal are both statutory aggravating factors. The lesson is that the specific number affects the severity of the charge, but it does not decide whether he is guilty of DWI at all.
