PACIFIC BEACH (KGTV)-- Memorial Day weekend is the unofficial start of summer, and police are bracing for partiers with maximum enforcement throughout the holiday.
At Pacific Beach dozens of motorized scooters pooled around two San Diego Police Officers. They educated dozens of riders on the rules, saying riders need to wear a helmet. They've given out dozens of tickets as well, since Friday.
Skateboards and roller skates are also not allowed on the boardwalk. Jake Kostreba said he rides on the boardwalk all the time and was frustrated at why he received a ticket, "I mean I guess someone needs to clean up the beach so, I'll be that guy, so whatever, it's pretty dirty."
Police say he lost control of his board and it hit a woman's shin.
Visitors told 10News they don't mind the extra police presence.
Ruqayyah Abdulrahoof drove down from Los Angeles, "I think it's really important to see the police over here especially with the kids and the beach I think it's really important to make sure the people have a good safe memorial day weekend and nobody's drinking I think it's a great place, and good to see officers are making an effort."
Scot Brantley came down with his wife and baby from Washington for a friend's crossfit tournament and echoed the sentiment, "I think we feel safe you know people are out here enjoying having a good time so nothing too crazy so far but it's early it's early though."
On the beach, lifeguards have been busy as well, rescuing 20 people and rendering medical aid to 47 Saturday. They also had more than 1,000 preventative interactions.
Lifeguards want you to know smoking and alcohol is never permitted at the beach.
Police geared up for a weekend of DUI checkpoints and extra patrols. Chula Vista, San Diego City and County will all have checkpoints set up, looking for impaired drivers. That includes medication as well as alcohol.
DUI arrests are up this year compared to 2017 on the same day. Friday night 24 people were arrested compared to 17 last year.
The maximum enforcement period continues through Memorial Day evening.
