Policing a mountain resort town: a Sheriff's contract city
Big Bear Lake does not run its own municipal police department. Since the city incorporated on November 28, 1980, it has contracted with the San Bernardino County Sheriff's Department for police service, and the Big Bear Lake Patrol Station at 477 Summit Boulevard is the result — a Sheriff's Station Commander acts as the city's de facto chief of police, working with the City Council on local priorities. The same station also patrols roughly 258 square miles of surrounding unincorporated mountain territory, including Big Bear City, Sugarloaf, Erwin Lake, Baldwin Lake, Lake Williams, and Fawnskin — communities distinct from, but easily confused with, the incorporated City of Big Bear Lake itself.
The mountain highways in and out of town add a second layer of enforcement. The California Highway Patrol's Arrowhead Area office, headquartered in Running Springs on SR-18, patrols the San Bernardino Mountains corridor — Crestline, Lake Arrowhead, Running Springs, Angelus Oaks, and the unincorporated community of Big Bear City — along with more than 500 miles of unincorporated mountain roadway. CHP's own office materials name "Big Bear City" specifically rather than the incorporated City of Big Bear Lake, and California's general practice gives CHP primary jurisdiction over state highways (including SR-18 and SR-38) even inside city limits, while the Sheriff's contract station handles arrests on Big Bear Lake's local streets — so a DUI stop on Big Bear Boulevard itself and a DUI stop on the open highway just outside town can end up in different agencies' hands.
- SR-18 (the "Rim of the World" route through Crestline, Lake Arrowhead, and Running Springs) and SR-38 (continuing from Big Bear Lake down through San Gorgonio Pass toward Mentone and Redlands) are the two highway approaches to Big Bear — both narrow, two-lane mountain roads.
- California law requires chains or snow tires in posted mountain zones in winter storms, and CHP commonly runs chain-control checkpoints on the Highway 330/18 corridor during storms — the same stretches that see DUI enforcement on weekend ski traffic.
- Tourist volume, not just population, drives enforcement patterns: a town of roughly 5,000 year-round residents can swell past 100,000 visitors on a busy ski weekend or summer lake weekend, concentrating drinking-and-driving risk around Big Bear Boulevard, the Village, and the two ski resorts (Snow Summit and Bear Mountain).
There's a courthouse right in Big Bear Lake — but it can't hear your DUI case
This is the detail that trips people up: Big Bear Lake has its own courthouse, the Big Bear District, sitting at 477 Summit Boulevard — the same address as the Sheriff's station. But the Big Bear District has no criminal jurisdiction at all. Its docket is limited to small claims, landlord-tenant cases, family law and child support, civil harassment restraining-order filings (the hearing itself is then set in Barstow), and limited remote traffic-infraction appearances — and its clerk's window is open just once a month, the first Wednesday, 9:30 a.m. to 1:30 p.m. The San Bernardino Superior Court's own "Where Can I File?" page spells out the rest in plain terms: "All Criminal Felony and Misdemeanor matters are filed and heard at the San Bernardino District – Criminal Division" — not in Big Bear.
That means a Big Bear Lake DUI — misdemeanor or felony — is filed and heard at the San Bernardino Justice Center, 247 West Third Street, San Bernardino, CA 92415, a drive of roughly 40-plus miles down the mountain on SR-18. The San Bernardino County District Attorney's Office prosecutes the case there, not any Big Bear authority. It's a genuinely easy mistake to make — there's a real courthouse building right in town — but showing up at the Big Bear District for a DUI matter accomplishes nothing; the case lives in San Bernardino from arraignment through trial.

A ski town and a lake town, 6,750 feet up
Big Bear Lake sits at roughly 6,750 feet elevation on the south shore of its namesake lake, inside the San Bernardino National Forest. Year-round, it functions as two different towns: a summer lake-recreation destination (boating, fishing, waterskiing, over 22 miles of shoreline) and a winter ski town built around two resorts, Snow Summit and Bear Mountain. The permanent population is small — about 5,046 at the 2020 Census — but the visitor count on a busy weekend regularly tops 100,000, which is the real driver of local DUI enforcement: it isn't a town of 5,000 people worth patrolling, it's a town that behaves like a small city every Friday and Saturday night in ski season and every summer holiday weekend.
California's Office of Traffic Safety does track Big Bear Lake in its annual city rankings, grouping it with other small cities of similar size (Group F, average population 4,977 in the 2023 data). Big Bear Lake's 2023 figures are a mixed, somewhat unusual picture: the city's reported DUI-arrest count for the year was recorded as zero, yet it ranked 1st out of 74 comparably sized cities for alcohol-involved collision victims (14) and for nighttime collisions, and 2nd out of 74 for total fatal-and-injury collision victims (57). Small-city OTS data can be volatile year to year and the zero-arrest figure in particular should be read with caution rather than taken as evidence that DUI stops aren't happening — the collision data points the opposite direction.
