In reviewing the State's disabled person parking placard program, the State Auditor wrote that "DMV does not sufficiently ensure applications for disabled person parking placards (placards) and disabled person or disabled veteran license plates (plates) are legitimate." It found that "out of 96 applications we sampled, DMV approved 70 applications that did not include sufficient medical information to demonstrate that the applicant qualified" and that projecting to all applications, "this suggests that DMV approved up to 1.1 million applications from July 2013 through June 2016 without sufficient information to demonstrate that the applicant was qualified." The report further estimates that, based on questionable medical provider signatures, "more than 260,000 applications approved from July 2013 to June 2016 may not be valid."

In Chapter 1, the auditor explains that a medical review of a representative sample of 96 original applications approved by DMV found that "70 applications, or 73 percent, did not include a full description of the illness or disability" and that projecting to the entire population "suggests that DMV approved up to 1.1 million applications from July 2013 through June 2016 without sufficient information to demonstrate that the applicant was qualified." The report further states that a sample review of provider signatures found that a percentage were "questionable" and, when projected, led to an estimate that "more than 260,000 applications approved from July 2013 through June 2016 may not be valid." These figures concern questionable or insufficient documentation for applications, not directly observed fraudulent use of placards in parking lots.

The California State Auditor’s summary notes that, as of June 2016, "DMV had more than 2.9 million active placards," which exceeds the estimated number of eligible individuals. The summary explains that auditors conducted "surveys of on-street parking in four cities" and observed vehicles using disabled person parking placards, but it emphasizes that their on‑street survey could not determine the percentage of fraudulent use with statistical precision. Instead, the report focuses on systemic vulnerabilities and estimates of invalid applications, not a fixed statewide figure such as “20% of placard use is fraudulent.”

Describing a March 2018 enforcement effort, the article states: "During the #SaveTheSpace campaign, DMV investigators in 20 enforcement operations from Oroville to San Diego contacted over 2,000 drivers who had parked in disabled person parking spaces" to verify placard legitimacy. It reports that "about 8% of contacted drivers were found to be using a placard fraudulently." It adds that "Drivers in Pomona and Stockton were particularly high rate offenders, with citation rates at 20% or greater."

California Vehicle Code section 4461 governs misuse of disability parking placards and plates. Subdivision (b) states that "a person to whom a disabled person placard has been issued shall not lend the placard to another person, and a person shall not knowingly use a placard that has been issued to another person" except when transporting that person. Subdivision (c) provides that a person shall not display a revoked, canceled, forged, counterfeit, or fraudulently obtained disabled placard or plate. Violations may be punished by specified fines and, when charged as a misdemeanor, by imprisonment in a county jail.

A committee analysis of legislation addressing disabled person parking placards cites DMV enforcement data to describe the scope of misuse. The analysis notes DMV field operations in which "approximately one in five individuals contacted for placard verification were found to be misusing a disabled person parking placard." It explains that misuse includes using a placard issued to someone else, using a deceased person’s placard, or using a canceled or revoked placard, and it uses this “about 20%” figure to support the need for additional enforcement and verification measures. The analysis presents this as an enforcement‑operation statistic, not as a formal, representative statewide fraud rate.

Senate Bill 611 (2017–2018) was introduced in part in response to the April 2017 California State Auditor report on disabled person parking placard misuse. The bill analyses reference the audit's findings that the DMV approved a significant number of placard applications without adequate medical information and that many permanent placards remained active for individuals who were deceased, contributing to opportunities for misuse. The bill materials discuss the need to address widespread abuse and to strengthen oversight but do not state that exactly 20 percent of disabled placard use in California is fraudulent.

The LAO report on the disabled placard program discusses concerns about misuse and cites DMV enforcement data. It explains that in focused enforcement efforts, DMV investigators "found that roughly 20 percent of the individuals they contacted who were using disabled placards were doing so in violation of state law." The report stresses that these figures arise from enforcement actions in areas where abuse is suspected and therefore "likely overstate the rate of misuse among all disabled placard users statewide." The LAO does not endorse a precise, system‑wide statistic such as “20% of placard use is fraudulent” for the general population.

In a formal opinion interpreting Vehicle Code provisions on disabled person parking placards, the California Attorney General discusses the legal framework governing issuance and use of placards and the penalties for misuse. The opinion explains that Vehicle Code section 4461 makes it unlawful to "lend a valid disabled person placard to another person" or to "display or cause or permit to be displayed a placard that was not issued to that person," and violations may be punished by a fine or imprisonment. While acknowledging that there is concern about abuse of placards, the opinion does not specify any quantified fraud rate such as 20 percent statewide.

The bill analysis for AB 2602 cites DMV enforcement data indicating that in recent operations, investigators found that approximately 20 to 25 percent of the disabled person parking placards they checked were being used fraudulently or in violation of state law. Lawmakers referenced this misuse rate to justify tightening eligibility and renewal requirements for disabled person placards.

The DMV’s official information page describes who qualifies for disabled person (DP) parking placards and plates, how they may be used, and the penalties for misuse. It emphasizes that a DP placard may only be used when "transporting the person to whom the placard was issued" and that misuse of a DP placard "is a crime and may result in cancellation or revocation" of the placard as well as fines. The page outlines lawful and unlawful uses but does not include any quantitative estimate (such as 20%) of fraudulent or improper placard use.

CSLEA reported on a 2017 enforcement operation in which California DMV investigators checked 121 people who were displaying a disabled person parking placard at a shopping center. Of those 121 people, 25 were found to be using the placard fraudulently and were issued citations. The piece notes that approximately 2.4 million people in California held permanent disabled person parking placards at that time, but this enforcement snapshot does not establish a statewide percentage; it only shows that about 20.7 percent of placards observed in that specific operation were being used fraudulently.

Discussing the California State Auditor’s report, the commentary notes that "California State Auditor Elaine Howle last month released an audit that confirms the abuse-racked nature of the Department of Motor Vehicles’ disability-parking system." It states that "the auditor sampled 96 applications for disability placards and plates and found that 70 of the applications lacked sufficient information to confirm that the applicant was really qualified for the permit." The piece characterizes the system as vulnerable to abuse, but does not quantify a statewide percentage of fraudulent use in disabled parking.

The fact sheet summarizing Report 2016‑121 states that the DMV "cannot demonstrate that it has taken sufficient steps to prevent the misuse of disabled person parking placards" and highlights that it approved up to 1.1 million applications from July 2013 through June 2016 without sufficient information. It also notes that auditors identified 26,000 placards issued to individuals listed as deceased and that some individuals received a high number of replacement placards. The fact sheet describes these issues as creating opportunities for misuse and fraud but does not quantify that a specific percentage, such as 20 percent, of all placard use is fraudulent.

Reporting on the State Auditor’s findings, the news segment says auditors "found roughly 26,000 permanent placards were issued for people 100 years old and over. But the problem is, the state's population of people 100 or older is only 8,000." The reporter states that according to the audit, "73% of approved [placard] applications lacked enough information" and concludes that "it is apparent there is abuse going on," though no specific statewide fraud percentage for placard use is cited.

A San Francisco Chronicle report describes increasing concerns among Bay Area officials about abuse of disabled parking placards, citing observations that some drivers use placards issued to other people or to the deceased. The article mentions spot enforcement stings that have found significant rates of improper use among the sample checked, sometimes around one in five drivers displaying placards in those operations. However, the piece presents these numbers as results of specific stings rather than as an official estimate that 20 percent of all disabled placard use statewide is fraudulent.

Public discussions of disabled parking placard fraud in California often reference figures from enforcement "stings" or audits rather than a single official statewide fraud rate. Operations in specific locations (for example, a county fair or individual cities) have reported misuse rates approaching 20 percent among drivers checked, while statewide DMV enforcement campaigns have reported lower rates around 8 percent of drivers contacted using placards fraudulently. These figures are context-specific snapshots and are not published by the state as a uniform statistic such as "20 percent of all placard use is fraudulent" across California.
