Know Your Checkpoints
What states do not conduct DUI checkpoints?
12 states do not conduct checkpoints: Alaska, Idaho, Iowa, Michigan, Minnesota, Montana, Oregon, Rhode Island, Texas, Washington, Wisconsin, and Wyoming. These states rely on saturation patrols instead.
Are DUI checkpoints legal?
Yes. The U.S. Supreme Court ruled that checkpoints are legal as long as they follow minimal intrusion and clear guidelines.
Can I legally avoid a checkpoint?
Absolutely. You can reroute or turn around as long as it’s done legally without violating traffic laws. Illegal U-turns or erratic behavior may raise suspicion.
Do I have to answer questions?
Nope. You have the right to remain silent. Simply hand over your license, registration, and insurance. Decline to answer questions respectfully.
Can I refuse a breathalyzer?
Yes, but most states have implied consent laws. Refusing can result in license suspension and fines—even if you aren’t convicted of DUI.
Where can I find checkpoint locations?
Follow your local police on social media, check news reports, or use apps like Waze to spot real-time community reports.

Sobering Up: The Truth & Your Options
Time is the only true path to sobriety—no magic pill, no shortcut. It takes about one hour per standard drink for your body to process alcohol. Coffee, cold showers, or energy drinks might perk you up, but they won’t lower your BAC.
Tips for Drinking Responsibly:
- Designate a sober driver before the night begins.
- Use a rideshare app or call a cab—your life is worth the fare.
- Know your limit and pace yourself with water between drinks.
- Eat a solid meal before drinking to slow alcohol absorption.
- Stay overnight if you're unsure—safety over convenience.
One bad decision can change everything. Be smart, be safe, and respect the power of time.
1 Hour Countdown
BAC (Blood Alcohol Concentration) reflects the amount of alcohol in your bloodstream. For example, a BAC of 0.08% means 0.08 grams of alcohol per 100mL of blood.
In the U.S., the legal BAC limit for drivers over 21 is 0.08%. For those under 21, it's much lower — often between 0.01% and 0.05%, depending on state law.
Alcohol may bring a short-term buzz, however long-term consumption has mixed consequences. Some studies suggest light to moderate drinking may reduce heart disease or stroke risk, but newer findings suggest these benefits may be minor — and come with **notable risks**.
Heavy drinking increases the chance of CVDCardiovascular Disease, liver disease, CNSCentral Nervous System damage, cancer, and more. If you don’t drink now — there’s no reason to start.
| BAC (%) | Behavior | Impairment |
|---|---|---|
| 0.001–0.029 | Appears normal | Minor effects detected only by tests |
| 0.030–0.059 | Mild euphoria, talkativeness | Reduced concentration |
| 0.060–0.099 | Disinhibition, extraversion | Reasoning, perception impaired |
| 0.100–0.199 | Over-expression, slurred speech | Severe motor skills reduced |
| 0.200–0.299 | Emotional swings, blackout | Severe motor impairment |
| 0.300–0.399 | Stupor, unconsciousness | Breathing & heart rate affected |
| 0.400–0.500 | Possible coma | CNS shutdown |
| > 0.500 | Critical condition | High risk Fatal |
Alcohol impairs more than judgment. Drive safe, drink responsible.
