A New Jersey CDL holder selects an excepted intrastate self-certification category but keeps a P/S endorsement. What medical filing rule applies?

1. The holder still needs an electronic MEC on file because New Jersey includes P and P/S holders regardless of commerce category
2. The holder never needs a MEC because all excepted drivers are exempt from P/S medical filing
3. The holder needs only a paper MEC kept at home
4. The holder needs a MEC only if also applying for hazmat
