In the event of getting caught for DIU, due to some procedural errors or untimely reporting to the administrative authorities, driving under the influence (DUI) and car insurance don't mix.
At times, there might be some disconnect between the administrative authority, the court and / or motor vehicle department due to which DUI convictions which should get delivered to the motor vehicle department falling in the court jurisdiction, does not happen. In this case, driver’s DUI offence may remain undisclosed.Thus, as a result of DUI offence for alcohol or intoxication remaining undiscovered form the car insurance, concerned DUI and the car insurance don’t mix. However, in all probability the insurance company can act harshly, smashing higher premium rates from the erstwhile DUI convict, even after many years of mishap.
Another counter measure to ensure DUI and car insurance don't mix is that the DUI convict does not wait for car insurance policy getting cancelled by the authorities and proactively approaches some other insurance company to buy a new one. Also some renowned insurance company may deny from insuring a DUI convict but some other’s may do so at a considerably premium cost. Local insurance agents dealing in vehicle may of help in this regard.
As a futuristic action, one should ensure that an old driving under the influence and car insurance don't mix by keeping up with a car insurance any ways. This may need higher premium payouts but save from driving without proper coverage. A noticeable fact is a DUI conviction can stay on convict’s record for many years but car insurance companies will typically only use it for 3 year premium or even less.
So, planning ahead and keeping an eye on future options is the best way even if one is found convicted for DUI, at least so long as he has decided not to drive drunk.
