As Mr. Gallagher said, they can check your arrest records in a background check, not just your court/conviction records. An expungement is unlikely in a guilty plea case, though I have gotten expungements granted in many such cases, it depends a lot on the county and how much time has passed since the offense (usually you need at least 5 years).

If it is less than 42.5 grams (1.5 oz.) and on your person (or in your house) but NOT in your car, it is a petty Misdemeanor, which is equivalent to a parking ticket; If it is in your car anywhere BUT in the trunk (in the console or the glove compartment for example) then it is a Misdemeanor called "Marijuana in a Motor Vehicle" which is a Misdemeanor, meaning you can go to jail for up to 90 days for that; If it is in your car BUT in the trunk AND 42.5 g. or less then it is again a Petty Misd....

Mr. G is right, as always. Since you are 17, you may possibly be prosecuted as an adult. Any conviction, whether as an adult or a juvenile, for theft is Very bad because it is a crime of dishonesty and if potential employers find out about it, they will not hire you. Get an attorney, whether a private atty. or a public defender, for aggressive defense to keep your record clean.
Mr. G is correct as always: it is NEVER a bad idea to plead Not Guilty. What you need to do is hire an experienced tough defense atty. asap. We , as others, offer a free initial consultation....952-913-1421
You will have an implied consent revocation of your DL on your (DL) record, unless you challenge it w/in 30 days of your arrest and win. On your criminal record you would have a conviction for careless (assuming that is what the prosecutor offered, since Reckless is not usually offered/accepted)...Can an employer check your driving record?: Yes, w/your permission. And if you refuse permission, they will not hire you.
