DUI Car Insurance Rates and State DUI Laws DWI Laws

There are many moral and legal reasons you should not drink and drive. With that in mind, why don’t we stick to a practical subject – your bank account! Before we go on, here is a Chart of DUI/DWI laws. I thought it would be useful to list for readers of this Blog the most current Driving Under the Influence (DUI) and Driving While Impaired Laws (DWI) by each state. This Chart and information was reproduced by written permission of Insurance Institute for Highway Safety who hold its copyright.

DUI/DWI laws

January 2009


All 50 states and the District of Columbia have per se laws defining it as a crime to drive with a blood alcohol concentration (BAC) at or above a proscribed level, 0.08 percent.

License suspension or revocation traditionally follows conviction for alcohol-impaired driving.  Under a procedure called administrative license suspension, licenses are taken before conviction when a driver fails or refuses to take a chemical test.  Because administrative license suspension laws are independent of criminal procedures and are invoked right after arrest, they’ve been found to be more effective than traditional post-conviction sanctions.  Administrative license suspension laws are in place in 41 states and the District of Columbia.

Some offenders in 47 states and the District of Columbia are permitted to drive only if their vehicles have been equipped with ignition interlocks.  These devices analyze a driver’s breath and disable the ignition if the driver has been drinking.

In 32 states, multiple offenders may have to forfeit their vehicles.

Laws prohibiting the driver, passengers, or both from possessing an open container of alcohol in the passenger compartment of a vehicle are in place in 43 states and the District of Columbia.

1Drivers usually must demonstrate special hardship to justify restoring privileges during suspension, and then privileges often are restricted.

2The 0.08 per se BAC law in Michigan contains a sunset clause which states that the legal BAC will revert to 0.10 on October 1, 2013.

3In New York, administrative license suspension lasts until prosecution is complete.

4In Tennessee, municipalities and counties can prohibit passengers from possessing an open container

Getting arrested for drinking and driving is an expensive proposition. First, you are going to pay a defense attorney at minimum several thousand dollars to defend you. Then you are going to pay court costs, fees and fines. The loss of your driver’s license and time in jail will also have an indirect financial cost as well. But wait there’s more. What happens to your car insurance premiums?

Insurance is all about calculating risk. The lower the risk associated, the lower the premiums for an insurance policy. The opposite is true as well. The higher the risk, the higher the premiums. Well, guess how insurance view your driving abilities if you have a conviction for drunk driving whether it be a DWI, DUI or whatever variation of the offense? You will be viewed as falling into the highest risk category they insure.

Some auto insurance companies may simply cancel your policy out right. For those that don’t expect your auto insurance premiums to increase significantly, probably four fold or five fold. That’s a lot of money particularly after the costs you’ve already paid for your DUI/DWI case. But wait, there’s more.

Your new, huge car insurance premiums are not going to last for just one year. They will be around for a minimum of the next 3 to 5 years!

There are plenty of reasons not to drink and drive. Just on money lost alone simply compare the insanely high cost of car insurance after a drunk driving conviction compared to the cost of driving before you were convicted. Financially, it just makes sense to let someone else drive if you are drinking.
