DUIs and insurance
In addition to the possible fines and jail time after a DUI conviction, you can expect some insurance pain. EverQuote found a 30% increase in car insurance after a DUI, based on premiums reported by our users with clean records vs. those with a DUI.
Depending on the state and number of DUIs, you may be required to get an SR-22, which proves you have auto insurance.
