Refusing a DUI Chemical Test in California
California’s implied consent law makes a refusal its own problem — at the DMV, at sentencing, and sometimes in how the night unfolds.
People refuse a chemical test believing it helps. Under California law it usually adds a second set of consequences on top of the DUI itself. This page explains the mechanics — it is not advice about what to do at a roadside.
Implied consent
Under Vehicle Code 23612, a person who drives in California is deemed to have consented to a chemical test of breath or blood if lawfully arrested for DUI. A refusal after a lawful arrest triggers consequences independent of whether the DUI is ever proved. This is different from the preliminary roadside breath screening that often happens before an arrest, which is treated separately for most adult drivers.
What a refusal adds
| DMV | A refusal carries a longer licence suspension or revocation than a failed test, and the length increases with prior DUI-related matters. |
| Criminal case | A refusal can be alleged as an additional factor that increases the consequences on conviction. |
| Evidence | The refusal itself can generally be used as evidence. Police may also seek a warrant for a blood sample. |
The 10-day DMV deadline
The DMV process is separate from the criminal case and has its own clock. A driver generally has 10 days from the arrest to request an administrative hearing, or the suspension takes effect automatically. This deadline passes quietly while families are focused on getting someone out of custody. Put it in the calendar the same day.
Does a refusal change the bail?
The bail figure comes from the countywide schedule for the DUI charge as booked, plus any additional charges and enhancements — see DUI bail and how enhancements change bail. A refusal matters more for the licence and for sentencing than for tonight’s bail number. What more often changes the figure is injury (DUI causing injury), priors (DUI with priors), or an outstanding warrant.
After release
Driving on a licence suspended for a DUI-related reason is its own offence under Vehicle Code 14601.2 — see driving on a suspended licence. The car is often towed; see getting property back.
