Most prom nights end the way they should. Tired feet, too many photos, a late snack somewhere. This page is about keeping it that way.
It is not a lecture. It is the practical stuff. How to plan the ride home, what the numbers actually say about alcohol and driving, what your school is likely to check at the door, and what to do if something starts to go wrong.
Why the ride home matters most
Prom happens during the hours when young drivers are most at risk. According to the Insurance Institute for Highway Safety, teenage crash deaths in 2024 happened most often between 9 p.m. and midnight, followed closely by 6 to 9 p.m. and midnight to 3 a.m. About half happened on a Friday, Saturday or Sunday. And the IIHS says teen crash deaths in 2024 peaked in June, right in prom and graduation season.
Inexperience is part of it. The IIHS says the fatal crash rate per mile driven for 16 to 19 year olds is just over three times the rate for drivers 20 and older. Passengers matter too. In 2024, 58 percent of teenage passengers who died in crashes were in a car driven by another teenager.
So decide how you are getting home before you decide anything else. Who is driving. What time. Where you are going afterward. And who you will call if that plan falls apart. Many states limit nighttime driving and passengers for newer drivers, and our guide to getting to prom explains those rules and how to book a car or bus safely.
Alcohol and driving, by the numbers
Drinking is illegal for anyone under 21 in every state. That is the law, and it is also the reason schools take it so seriously on prom night. The numbers explain why.
In its report on 2023 data, the National Highway Traffic Safety Administration counted 12,429 people killed in 2023 in crashes involving an alcohol-impaired driver. That was 30 percent of all U.S. traffic deaths, or one death every 42 minutes. Among drivers aged 15 to 20 involved in fatal crashes that year, 20 percent were over the legal limit. NHTSA also found that alcohol impairment among drivers in fatal crashes was three times as common at night as during the day.
The IIHS adds an important detail. Young drivers are less likely than adults to drink and drive, but their crash risk climbs faster when they do, especially at low and moderate blood alcohol levels. In other words, a teenager does not have to be obviously drunk to be dangerous behind the wheel. Drugs, including marijuana and some prescription medicines, impair driving too.
The safest rule is simple. Do not drive after drinking or using anything, and do not get in a car with anyone who has. NHTSA's own advice is to plan a safe ride home before you go out, and to take the keys and find another ride for anyone who should not be driving.
What schools check at the door
Schools know the risks, and many build safety into prom itself. Expect at least some of the following.
- Breath tests. The Freehold Regional High School District in New Jersey says all students attending prom may be asked to take a breathalyzer test on the way in, during the dance or on the way out, and that administrators may use passive alcohol sensors.
- Bag rules and searches. Liberty High School in Pennsylvania allowed only small clutches, no bigger than 6 by 4 inches, and said they could be searched. Jefferson High School in Bloomington, Minnesota allowed no bags at all.
- No leaving and coming back. Liberty and Elmwood High School both said that once you leave, you cannot return. Freehold Regional does not let students step out to the parking lot or to limos during the dance.
- Serious consequences. Freehold Regional says anyone under the influence will be reported to police, removed from prom and suspended, and that seniors will not be allowed to take part in graduation.
These rules can feel heavy. But they also mean the dance itself is one of the most supervised places you will be all night. The riskier hours tend to come after it ends.
Make a plan with your parents
Schools are clear about where their responsibility stops. Freehold Regional's rules say staff supervise students during prom, that parents take over from the moment of dismissal, and that families are asked to supervise activities before and after the dance.
A good plan covers a few things. Where you will be before prom, during it and after. Who you are with. When you will check in, and how. Keep your phone charged and consider sharing your location for the night. Then add one more agreement, the most important one.
Agree that you can call for a ride at any hour, from anywhere, with no questions asked that night. The conversation about what happened can wait until the next day. This takes away the pressure to get into a car you should not get into, because you always have a better option. Parents, if you make this promise, keep it.
After-prom is the safer option
Many schools and parent groups run a supervised after-prom, often with food and games late into the night. Oak Lawn Community High School in Illinois sold 2026 post-prom tickets for $35, picked students up at the prom venue and brought them back to school. Elmwood High School's after-prom ran overnight, into the next morning. If your school has one, it is the easiest way to keep the night going without a driving problem. Our page on what happens at prom describes the rest of the evening.
Looking out for each other
- Arrive together and leave together. Do not let a friend leave alone with people they just met.
- Keep your drink with you. If you set it down or it was handed to you open, get a new one.
- Pick a meeting spot in case phones die or the group gets split up.
- Eat something before the dance, especially if dinner and prom are hours apart.
- Trust your gut. If a party or a ride feels wrong, leave and call your backup.
If something goes wrong
If someone is hurt, cannot be woken up, or is having trouble breathing, call 911 right away. Stay with them, and do not leave them to sleep it off. Getting help is always the right call.
For anything less urgent, find a chaperone or a school staff member at the venue, or call your parent. If your ride turns out to be impaired, do not get in. Call your backup ride instead. If you see something that worries you about someone else, tell an adult. That is not getting a friend in trouble. It is getting them home.
Then go back to enjoying yourself. The point of all this planning is to let you forget about it once the music starts. If you are still sorting out your outfit, you can browse prom shops by state.
