SAN FRANCISCO – California must revoke permits allowing federal agencies such as Customs and Border Patrol (CBP) and the Drug Enforcement Administration (DEA) to put automated license plate readers along border highways, a coalition led by the Electronic Frontier Foundation (EFF) and Imperial Valley Equity & Justice (IVEJ) demanded today. 

In a letter to Gov. Gavin Newsom and California Department of Transportation (Caltrans) Director Dina El-Tawansy, the coalition notes that this invasive mass surveillance – automated license plate readers (ALPRs) often disguised as traffic barrels – puts both residents and migrants at risk of harassment, abuse, detention, and deportation.  

“With USBP (U.S. Border Patrol) Chief Greg Bovino reported to be returning to El Centro sector, after leading a brutal campaign against immigrants and U.S. citizens alike in Los Angeles, Chicago, and Minneapolis, it is urgent that your administration take action,” the letter says. “Caltrans must revoke any permits issued to USBP. CBP, and DEA for these surveillance devices and effectuate their removal.” 

Coalition members signing the letter include the California Nurses Association; American Federation of Teachers Guild, Local 1931; ACLU California Action; Fight for the Future; Electronic Privacy Information Center; Just Futures Law; Jobs to Move America; Project on Government Oversight; American Friends Service Committee U.S./Mexico Border Program; Survivors of Torture, International; Partnership for the Advancement of New Americans; Border Angels; Southern California Immigration Project; Trust SD Coalition; Alliance San Diego; San Diego Immigrant Rights Consortium; Showing Up for Racial Justice San Diego; San Diego Privacy; Oakland Privacy; Japanese American Citizens League and its Florin-Sacramento Valley, San Francisco, South Bay, Berkeley, Torrance, and Greater Pasadena chapters; Democratic Socialists of America- San Diego; Center for Human Rights and Privacy; The Becoming Project Inc.; Imperial Valley for Palestine; Imperial Liberation Collaborative; Comité de Acción del Valle Inc.; CBFD Indivisible; South Bay People Power; and queercasa. 

California law prevents state and local agencies from sharing ALPR data with out-of-state agencies, including federal agencies involved in immigration enforcement. However, USBP, CBP, and DEA are bypassing these regulations by installing their own ALPRs. 

EFF researchers have released a map of more than 40 of these covert ALPRs along highways in San Diego and Imperial counties that are believed to belong to federal agencies engaged in immigration enforcement.  In response to a June 2025 public records request, Caltrans has released several documents showing CBP and DEA have applied for permits for ALPRs, with more expected as Caltrans continues to locate records responsive to the request. 

“California must not allow Border Patrol and other federal agencies to use surveillance on our roadways to unleash violence and intimidation on San Diego and Imperial Valley residents,” the letter says. “We ask that your administration investigate and release the relevant permits, revoke them, and initiate the removal of these devices. No further permits for ALPRs or tactical checkpoints should be approved for USBP, CBP, or DEA.” 

"The State of California must not allow Border Patrol to exploit our public roads and bypass state law," said Sergio Ojeda, IVEJ’s Lead Community Organizer for Racial and Economic Justice Programs.  "It's time to stop federal agencies from installing hidden cameras that they use to track, target and harass our communities for travelling between Imperial Valley, San Diego and Yuma."
