In 2024, nearly one in three traffic deaths in Arizona involved alcohol. Alcohol played a role in 347 traffic deaths across Arizona, more than 28% of all fatalities on state roads that year. Most of those deaths were preventable. And many of them come down to the same missing piece: a group standing in a parking lot, arguing about who’s sober enough to drive, because nobody figured it out earlier.

Why Designated Drivers Matter
Here’s the thing about designated drivers: everyone says they’ll have one, but the plan often falls apart around midnight when the “sober” friend has had two drinks, and nobody wants to be the one to say something.
The numbers back that up. Male drivers were involved in over 71% of Arizona’s alcohol-related crashes in 2024, and drivers between 25 and 34 made up the largest single age group in those crashes. This isn’t happening at high school parties. It’s happening at happy hour, birthday dinners, weddings, the kind of night nobody thinks twice about until it goes wrong.
According to ADOT’s 2024 crash data, alcohol-related crashes involved drivers across multiple age groups. Drivers ages 25–34 represented the largest group, reinforcing that impaired driving is not limited to one type of person or occasion. What this tells us is that the issue was not a single person making a bad choice. A plan can sound airtight at 6 p.m. and be forgotten three drinks later.
We hear this a lot from families who come through Stonewall’s classes: almost nobody planned to drive impaired. Most had a plan; it just didn’t have a backup. That gap, more than anything else, is what good DUI prevention tips actually try to close. Knowing your safe ride options in Arizona makes the difference between a normal Friday night and a phone call nobody wants to make.
How to Set Up a Designated Driver Plan
How to be a designated driver starts before anyone orders a drink, not after. Planning a safe night out takes maybe five minutes of conversation with your group, five minutes that can be the only thing standing between a normal night and a bad decision.
A few things that actually work:
- Pick the driver before you leave, not after a few rounds. Waiting until someone “seems fine” to decide is how plans fail.
- Rotate the role among your group. If the same person is always the driver, they’ll eventually skip a turn, and there won’t be a backup.
- Confirm out loud that the driver is actually staying sober. A quick “you’re good for tonight, right?” earlier in the night beats a tense conversation later, when everybody’s ready to go home.
- Build in a backup before you need one. Save a rideshare app, a cab company number, or a sober ride program to your phone before the night starts, not while you’re standing outside a bar arguing about it.
Rideshare apps like Uber and Lyft are the most common backup for a reason: they’re fast, they’re everywhere in Phoenix and the surrounding valley, and they don’t require anyone to negotiate with a friend who’s had too much to drink.
Some bars and venues also partner with local sober ride programs during busy weekends and holidays, so it’s worth asking ahead of time if your venue offers one. Those programs, along with rideshare and cab services, make up most of the safe ride options in Arizona; groups you can lean on when the original plan doesn’t hold up.
Being honest with your group about limits matters just as much as picking someone in the first place. If you’re not up for it that night, say so early, so someone else can step in before the group is already at the bar. That’s really the whole skill of how to be a designated driver: speaking up early instead of quietly hoping it works out.
What to Do When Plans Change
Plans fall through. The designated driver has a drink they didn’t mean to have, someone’s ride cancels, or the group splits up, and now three people need a way home instead of one.
When that happens, there are a few things you can do:
- Open a rideshare app immediately. Don’t wait to see if things “sort themselves out.”
- Call a friend who isn’t drinking, even if they weren’t part of the original plan. Most people would rather get a 1 a.m. call than a much worse one the next morning.
- Look up local sober ride alternatives in Phoenix. Bars and event venues often have a list for holidays like New Year’s Eve or the Fourth of July. Some are free or discounted specifically to keep impaired drivers off the road.
- If nothing else works, stay where you are. A couch, a hotel room, or an Uber home in the morning is always cheaper than a DUI, and it’s a lot cheaper than a crash.
None of this requires a hard conversation or a confrontation. It just requires having the app already downloaded and the number already saved, so the decision is easy to make in the moment.
Some nights, that decision isn’t just yours. Police are paying closer attention too. Phoenix-area police step up patrols on corridors like Mill Avenue in Tempe and the Loop 101 during big holiday weekends, and AZDPS runs coordinated enforcement through its Arrive Alive Arizona campaign around dates like New Year’s Eve and the Fourth of July. Those are also the nights when local venues are offering sober ride alternatives in Phoenix, so it’s worth checking before you go out, since many of these programs aren’t advertised outside that one weekend.
Prevention and backup work together. Planning a safe night out covers the first half. Knowing what to do when that plan slips covers the second. Having both in place is what actually keeps people off the road impaired.
If Someone You Love Already Has a DUI, How to Help
If you’re reading this because someone you care about already got a DUI, you’re probably not looking for DUI prevention tips. You’re trying to figure out how to help without making things worse, and helping a friend with a DUI looks a lot different than helping them avoid one in the first place. And it starts with a few things most people get wrong:
Skip the lecture. By the time someone’s dealing with a DUI, they already know it was a bad night. What they usually need is someone to help them figure out what to do after a DUI, not another reminder of what went wrong.
Understand what the process actually looks like. In Arizona, a first DUI typically involves court dates, mandatory classes or screening, fines, and license consequences that vary depending on blood alcohol level and any prior history. It’s a lot to navigate alone, especially for someone who’s never been through the court system before.
Offer specific, practical help. “Let me know if you need anything” is easy to ignore. “I can drive you to your class Tuesday” or “I’ll help you find your court paperwork” is a lot harder to turn down, and a lot more useful.
In the classes we run at Stonewall Institute, many people say they wish someone close to them had just handed them a checklist instead of a lecture. Small, specific offers tend to land better than big, vague ones.
Recognize this is common, and workable. DUI arrests happen to people from every background, every income level, and every age group. It doesn’t make it less serious, but it does mean your friend or family member isn’t facing something unusual or unfixable.
Watch your language. Terms like “loser” or “drunk driver” tend to shut people down instead of opening them up. Most people going through this already feel plenty of shame. They don’t need more of it from the people closest to them.
Helping a friend with a DUI isn’t about fixing anything. It’s about staying present. Being there for someone after a DUI doesn’t take legal knowledge or the perfect thing to say, just consistency and the absence of judgment they might be bracing for.
Stonewall DUI Services provides alcohol screening services in Arizona, and if you’re not sure what screening, education, or treatment actually involves, this breakdown explains the difference. Not a fix, just one less thing for your friend or family member to have to figure out on their own.

FAQ
What counts as a designated driver legally?
A designated driver is someone who agrees to remain completely sober so they can drive the group home safely. There is no special certification involved. Because alcohol can affect judgment before someone reaches a BAC of 0.08%, the safest standard for a designated driver is no alcohol.
Can a designated driver have any alcohol?
A designated driver should not drink. BAC estimates are unreliable, and Arizona drivers may face DUI consequences when alcohol impairs their ability to drive even if their BAC is below 0.08%.
What if I’m the one facing a DUI?
If you’re the one facing a DUI, you’re not alone, and there are people who can walk you through what comes next without judgment. Stonewall DUI Services provides ADHS-licensed online DUI screening, education, and treatment services for Arizona clients. Our team can help you identify the service listed on your court or MVD paperwork and complete it through a clear, confidential, and nonjudgmental online process.
What should I do if a friend insists on driving after drinking?
Do not get into the vehicle or allow them to drive others. Hold onto the keys when it is safe to do so, call a rideshare service or sober friend, or arrange for everyone to stay where they are. When immediate safety is at risk, contact local emergency services.
What happens at a first DUI class in Arizona?
Requirements vary by case. An Arizona DUI screening is generally used to determine whether education or treatment is required and how many hours must be completed. Clients should follow the requirements listed in their court or MVD paperwork. Stonewall provides qualifying DUI screening, education, and treatment programs online.
