Driving and DUI Laws in Washington State

The driver is responsible for understanding the DUI laws in the state of Washington. Drinking under the influence can result in a loss of license and the need to drive by using an ignition interlock device.



Laws vary from state to state and can often be confusing; the laws regulating DUI laws and penalties in Washington are strict and complicated. People who are operating a car or truck while under the influence need to be aware of the laws and what that might mean for them.

Why You Need to Know the DUI Laws in Washington State

The implied consent law states that every driver of a licensed vehicle, in the state of Washington, automatically consents to a blood test or breath test when stopped by a law officer. To refuse is to risk having one’s license taken away for at least a year.

If, upon taking the test, a driver is found to have a Blood Alcohol Content (BAC) level meeting the legal definition of ‘driving under the influence’ he or she can face a revoked or suspended license from 90 days to as much as 4 years. The length of time is dependent upon any previous offenses and the BAC level.


The Usefulness of an Ignition Interlock Device

Individuals who have a suspended or revoked license may qualify for an Ignition Interlock Device under the DUI laws in Washington State. The Ignition Interlock Device, or IID, allows people to drive during the period of suspension, as long as the vehicle has been equipped with the device. Applications are available through the Department of Licensing. Although every vehicle must have a IID installed, it is possible for employers to file for exemptions, if driving is a required part of one’s job.

The purpose of the IID is to monitor the blood alcohol level of the driver at all times. The device requires blowing in a mouthpiece to start the engine and it records all information in its databanks. The device is programmed to regularly require additional testing while the car is in operation. It is registered with the state and subject to specific rules about when it must be recalibrated.


Ignition Interlock Device Installers: Important Services to Look For

It’s important to find the right installer of your IID, one who understands the sensitive nature of a DUI conviction. The best company to hire should provide round the clock emergency service; should your device malfunction they should be able to provide mobile services to come help fix your IID. The device is not particularly complicated but a company, like Interlock NorthWest, will be able to teach the driver how to use the device as well as provide scheduled testing and recalibration as needed. Getting a license back with a minimum amount of time and complication can depend on how well the driver understands and complies with the DUL laws and penalties.

The interlock ignition device stores data about usage, blood alcohol level tests and the service records of the device. This information is used by the state in deciding about when to reinstate your license, you cannot risk not following the directions exactly as laid out by the state. When choosing the installer of your IID you want a company with a strong customer service record, an understanding of the law and the device itself. Your ability to get your life back to normal as quickly as possible can be improved with the right Interlock Ignition Device installer.
