Costa Mesa Personal Injury Attorney

Costa Mesa is a difficult city in which to ride a bicycle. State data for 2023 counted 89 bicyclists killed or injured here, ranking the city 3rd-worst of 62 comparable cities; it also ranked 4th-worst for speed-related crashes and 5th-worst on the state’s composite measure (OTS 2023). If you were hurt on Harbor Boulevard, Newport Boulevard or West 19th Street, those figures are the background to your claim, and a Costa Mesa personal injury attorney will rely on them when an insurer calls your crash an isolated event.

• All victims: 685 (10th)
• Speed-related: 115 crashes (4th)
• Alcohol-involved: 84 victims (9th)
• Arrests for DUI: 791
• Late night: 72 crashes (8th)
• Motorcyclists: 44 (11th)

Why the bicycle ranking matters

Eighty-nine victims in a city of about 108,881 people (Census 2025 estimate) is not a one-year anomaly. UC Berkeley’s SafeTREC and Cal Walks, working from SWITRS records, counted 238 bicyclists killed or injured between 2014 and 2018, one fatally and ten with suspected serious injuries. Those crashes were concentrated on Harbor Boulevard, West 19th Street and Newport Boulevard (SafeTREC 2020).

A cyclist’s claim usually turns on right-of-way at a driveway or intersection and on whether the driver saw the rider. Insurers resist these claims and often suggest the rider “came out of nowhere.” Helmet-camera footage, the speed log from a bike computer and the damage pattern on the frame answer that suggestion better than anyone’s memory; our bicycle accident page describes other useful evidence.

Tip: Do not repair or discard the bicycle. A bent fork or scraped crank shows the angle of impact, and an adjuster’s photograph is no substitute for the bike itself.

Questions about children, e-bikes and the fairgrounds

My 12-year-old was hit near 19th and Wallace. Is anything different for a child?

The fault rules are the same, but the timing is not. A minor’s deadline to file a lawsuit generally does not begin until the child turns 18, and a settlement for a child usually requires a judge’s approval. A parent’s claim for the child’s hospital bills can expire sooner than the child’s own claim, which is a good reason to act early.

I was riding an e-bike on Harbor Boulevard. Am I treated as a cyclist?

In most cases, yes, although the class of e-bike and where you were riding can affect the arguments about fault.

I slipped in a parking lot at the fairgrounds. Is that a car accident claim?

No. It is a premises liability case, brought against whoever controls the property rather than against a driver. Roughly 4.3 million visitors a year pass through the OC Fair & Event Center, so its lots and walkways see heavy use. Photographs of the surface, the lighting and any warning signs, taken the same day, are the most valuable evidence. For a fall at the fairgrounds, our premises liability page covers the duty an event operator owes the public.

Pedestrian deaths on Newport Boulevard

The same SafeTREC study found 162 pedestrians killed or injured from 2014 to 2018, including 9 deaths and 21 severe injuries. Where those deaths occurred is the most telling part of the data.

Newport Boulevard and 17th Street

At the SafeTREC workshop, residents described 17th and Newport as one of the city’s most intimidating intersections, with heavy foot traffic and a wide crossing. In 2025 the City Council adopted a resolution asking for safe-street improvements on State Route 55 where it runs as Newport Boulevard (America Walks).

Harbor Boulevard near Orange Coast College

Harbor near the college had the second-largest cluster of pedestrian crashes and is one of the city’s main bicycle corridors. At West 19th and Harbor, pedestrians face an eight-lane crossing, and they told researchers the signal did not give them enough time to cross.

West 19th Street

According to America Walks, traffic calming at 19th and Placentia, along with curb extensions and a pedestrian signal installed at 19th and Wallace in 2024, nearly eliminated collisions at those corners. That before-and-after record can matter in a claim, because it shows the danger was known and could be corrected.

Whether Caltrans or the city owns the road

Many people do not realize that Newport Boulevard between 17th and 19th Streets is a state highway segment owned by Caltrans, according to the SafeTREC report. If a dangerous design or a broken signal on that stretch contributed to your injury, the responsible public entity may be the State of California rather than the city.

Whether the State or the City of Costa Mesa is responsible, the written claim is generally due six months after the injury (Gov. Code §911.2). Naming the wrong agency can use up that short period, so the first task is to identify who owns the road.

Watch out: Claims against the state go to its Government Claims Program, not to Costa Mesa City Hall. A letter sent to the wrong office does not stop the six-month clock.

When pedestrian crashes peak

From 2014 to 2018, pedestrian crashes peaked on Fridays and Saturdays between 3 and 9 p.m. SafeTREC found the leading cause was a driver failing to yield at a crosswalk, in 25.2% of cases.

Weekend crowds also head to the OC Fair & Event Center, which drew 1,162,872 visitors to the 2025 fair and hosts more than 150 events and roughly 4.3 million visitors a year (OC Fair). Event traffic, crossings through parking lots and rideshare pickups all increase the chance of a low-speed pedestrian collision that still breaks bones.

Failure to yield and the presumption of negligence

The 25.2% figure has a statute behind it. Drivers must yield to a pedestrian in a marked or unmarked crosswalk at an intersection (Veh. Code §21950). When a driver violates a safety statute and causes the kind of injury the law was meant to prevent, California presumes the driver was negligent (Evid. Code §669). For a pedestrian struck in the Harbor crossing near Orange Coast College, that presumption puts the burden on the driver to explain why they did not stop.

The same reasoning helps motorcyclists, who accounted for 44 of the city’s 2023 victims. California permits lane splitting (Veh. Code §21658.1), so an adjuster cannot treat a rider as automatically at fault for moving between lanes on the 405 or SR-55. Speed and conditions still matter; our motorcycle accident page explains how these claims are valued.

DUI arrests and what they mean for your claim

No Group B police department arrested more impaired drivers in 2023 than Costa Mesa’s, with 791 DUI arrests. If the driver who hurt you was arrested for DUI, the fault case is stronger, and the arrest report, the breath or blood results and any criminal case file become evidence in the civil claim. The criminal prosecution and the injury claim proceed separately, and the civil claim does not have to wait for a guilty plea or verdict.

One limit surprises many families. California largely protects bars and restaurants from liability for serving an adult who later drives and causes a crash (Civ. Code §1714). The statute leaves one narrow opening: a licensed seller who served a visibly drunk patron under 21 can be held liable (Bus. & Prof. Code §25602.1). In most local DUI cases, therefore, compensation comes from the drunk driver’s insurance and your own uninsured motorist coverage.

Checklist for a crash on Harbor or Newport

• Call 911. Costa Mesa Police handle city streets, and the CHP Santa Ana Area covers I-405 and SR-55 (CHP Santa Ana).
• Let paramedics decide where to take you. Keep every discharge paper, whether you are treated at UCI’s Level I trauma center in Orange (Wikipedia) or at the Level II program at OC Global in Santa Ana (OC EMS).
• Photograph the crosswalk, signal and lane markings, particularly at 17th and Newport or 19th and Harbor.
• If an OCTA bus was in the area, its onboard cameras may have recorded the crash; ask OCTA and the shops along the block to keep that footage.
• Write down the police case number before you leave.
• Say as little as possible to the other driver’s insurer until you know the extent of your injuries.

Deadlines, shared fault and the Central Justice Center

A driver or rider hurt anywhere in Costa Mesa generally has two years to sue the motorist at fault (CCP §335.1). If a jury decides you rolled through the stop sign at 19th and Placentia and assigns you 30% of the fault, you still recover the other 70% (CACI 405). Recoverable losses go well beyond the emergency room bill to include lost wages, therapy that may continue for months, and pain and suffering.

A Costa Mesa injury case that cannot be settled goes to the Central Justice Center, the Orange County Superior Court’s main civil building in Santa Ana (OC Superior Court).

Hiring a Costa Mesa personal injury attorney

The Law Offices of Jacob Emrani regularly hears from cyclists on West 19th Street, pedestrians crossing Newport Boulevard and drivers rear-ended on the 405. If you are looking for a Costa Mesa car accident attorney or a lawyer for a bicycle crash, we can review what happened with you. Given the city’s bicycle ranking and the deaths on Newport Boulevard, it is no surprise that riders and people on foot account for much of what we handle in Costa Mesa; DUI crashes, motorcycle collisions, falls at the OC Fair grounds, dog bites and wrongful death claims make up the rest. When Caltrans owns the stretch of Newport Boulevard where you were hurt, we file the claim with the state within the six-month period rather than with City Hall. A consultation about a Costa Mesa crash is free; after that, you pay nothing unless we win. If a Harbor Boulevard crash has left you unable to travel, we can come to your home or workplace.

Our number is (888) 952-2952. You can also describe what happened on the evaluator form, and Spanish-speaking families can read our site at calljacob.com/es.
