California DMV reportedly suspects thousands of drivers cheated on written tests

Thousands of California-licensed drivers are being required to retake their written tests because the DMV reportedly suspects them of cheating.

Last month, the DMV sent letters to some 11,000 drivers saying that their knowledge test results showed "irregularities." That sparked confusion and frustration, but the department did not provide specifics about what issues were found with those tests.

Some speculated there were technical or clerical issues.

But those irregularities are "test taker related," according to a DMV statement cited in a report from the Los Angeles Times, and not an internal issue or the result of artificial intelligence.

The Times report states that DMV identified patterns in the results of driver knowledge tests indicating that some individuals "may have attempted to circumvent the testing process using various cheating methods."

Further information about those suspected patterns of cheating were not disclosed.

Meanwhile, an unspecific number of those cases have been referred to district attorneys for prosecution, according to the Times.

Drivers who received the letter must retake the written test within 30 days or have their licenses revoked.
