This section gathers practical rules and programs that do not fit neatly elsewhere but matter for everyday driving: seat belts and child restraints, insurance, disclosing health conditions, saving fuel, and a few state programs. Taken together, they help you stay legal, safe, and prepared. Several also involve specific Wisconsin DMV forms you should know about.
Wisconsin law requires you and all your passengers to wear seat belts at any age, and you must fasten your belt before driving even if the vehicle has air bags. The lap belt should fit snugly across your hip bones just under your stomach and the shoulder belt across your chest; never put the shoulder belt under your arm or leave it hanging loose. Generally, children must be in a child safety seat until age four and in a booster seat until age eight. You must also carry valid liability car insurance and show proof if an officer requests it — the insurance must be from an approved Wisconsin business, though an out-of-state driver may use proof from their own state; if you drive someone else's car, it is your job to make sure it is insured.
The section also covers ways to disclose conditions, save resources, and give back. You can report an invisible disability to the DMV using form MV2167, which is available to law enforcement and WisDOT employees, and you should report health conditions that could affect your driving on the Driver License Application MV3001. A free ID for voting is available to Wisconsin citizens who are at least 17 and U.S. citizens (forms MV3004 and MV3012). You can save fuel by carpooling, ride sharing, biking, taking a bus or walking, avoiding heavy traffic, and slowing gradually — and remember low tire pressure lowers fuel mileage. The Driver Education Grant Program helps pay for training of income-eligible teens, and you can register as an organ and tissue donor; at age 18 or older your donor decision may not be overridden by anyone.
