Depends. In California, evidence of prior felony convictions can be used to impeach your credibility (question your truthfulness) if the judge determines its relevance to your honesty is more important than the risk of unfairly prejudicing the jury. The prior conviction must be relevant to credibility, and the judge must balance its value against potential harm.

This applies to California state courts.

Trial judges must carefully weigh the probative value of prior convictions against their prejudicial effect under Evidence Code Section 352 when deciding whether to admit them for impeachment. They must provide clear limiting instructions to the jury.
