What could they sentence me with after I got a ticket for allowing someone to drive my car drunk?

If you need specific legal advice for your particular circumstances, I encourage you to privately consult with a lawyer. If you are charged with an offense and cannot afford to pay for your own defense, the court may appoint you an attorney payable at the public’s expense. You have a right to counsel. Anyone charged, of course, is presumed innocent. The prosecutor would need to prove the elements of the offense beyond a reasonable doubt if the matter proceeded to trial. Simply because a person is charged does not mean that ultimately, they will be convicted. Please note that this response is only focused on one potential component of a situation involving allowing an intoxicated or impaired operator to use another person's vehicle; it does not explore the possible civil issues (i.e., the owner could be sued through the civil process) or the possible administrative (i.e., there could be significant license sanctions if convicted) sanctions. Owners and operators may be charged if they allow someone to operate their vehicle while intoxicated or impaired. As noted in MCL 257.625 (2): The owner of a vehicle or a person in charge or in control of a vehicle shall not authorize or knowingly permit the vehicle to be operated upon a highway or other place open to the general public or generally accessible to motor vehicles, including an area designated for the parking of motor vehicles, within this state by a person if any of the following apply:(a) The person is under the influence of alcoholic liquor, a controlled substance, other intoxicating substance, or a combination of alcoholic liquor, a controlled substance, or other intoxicating substance.(b) The person has an alcohol content of 0.08 grams or more per 100 milliliters of blood, per 210 liters of breath, or per 67 milliliters of urine or, beginning October 1, 2018, the person has an alcohol content of 0.10 grams or more per 100 milliliters of blood, per 210 liters of breath, or per 67 milliliters of urine.(c) The person's ability to operate the motor vehicle is visibly impaired due to the consumption of alcoholic liquor, a controlled substance, or other intoxicating substance, or a combination of alcoholic liquor, a controlled substance, or other intoxicating substance. The consequences for a conviction for the owner or controller of the vehicle depend on the underlying charge for operator of the vehicle. MCL 257.625 (10) explains the list of possible maximum penalties in terms of jail/prison and fines. If, for example, the intoxicated operator caused a death, the person who permitted the operator to use the vehicle may be charged with a felony "punishable by imprisonment for not more than 5 years or a fine of not less than $1,500.00 or more than $10,000.00, or both." MCL 257.625 (10) (b). However, more likely, an owner or controller of the vehicle will be charged with a misdemeanor, “punishable by imprisonment for not more than 93 days or a fine of not less than $100.00 or more than $500.00, or both." MCL 257.625 (10)(a). Obviously, the prosecutor would need prove the “authorize or knowingly permit" portion of this charge against the owner/person in charge of the vehicle; however, that would be a question of fact that may not be resolved until a trial. I recommend you retain a lawyer or ask the court to appoint you a lawyer to assist you with this matter.
