At the Pride Festival, a bank of taxis and rideshare vehicles waited to take partiers to their next destination.
On the sidewalk, some drunkenly stumbled as they made their way through the crowds.
"We want to give everybody the opportunity to understand what they're doing when they're drinking, so that they understand when they're at that legal limit or at the same time understand the impairment behind their drinking," Sgt. Alonzo Alexander with SDPD said at the Know Your Limit Booth.
This is the second year the booth, funded by a MADD grant, has been at PRIDE.
Partiers were excited to see how they measured up, and some shocked they weren't as drunk as they thought.
"I'm sobering up, okay guys time to get a drink," Lacey Yelverton said. "I love the cops, and we wanted to see how much alcohol we had to drink and so we found out."
"When you're drinking, and you lose the whereabouts of making good sound decisions, it impacts everyone," Sgt. Alexander said.
What many don't know is while the legal BAC limit to drive is .08, drivers can still get pulled over and arrested for driving while intoxicated with a lower BAC. Paying for a DUI is steep.
"Most of these first time DUIs are $15,000+ dollars," Sgt. Alexander said.
An alternative is rideshare companies like Lyft. They are one of the sponsors for Pride and offer first-time riders $5 off their first two rides.
Back at the booth, "I think it's a great way to get the word out there and make sure everyone's safe about drinking and not driving," Yelverton said.
