Yes you can. If your plan is to sleep it off in your car, you need a new plan. If you believe you are too intoxicated to drive and decide to sleep it off in your car, you can be arrested, charged, and convicted of a DUI. How is this possible? The DUI laws are written in such a way that you do not need to be driving your car, you need to be in control of your car. If you are in the front seat with your keys in your pocket, you are in control of your car while under the influence of alcohol. So plan ahead, and do not rely on your vehicle as safe refuge. Also, remember if you decide to walk home instead of drive, they can also get you for public intoxication, so have a plan to get home and execute it.
