In Oregon, a minor driving without a license or permit is committing a serious offense known as operating a vehicle without driving privileges. This is classified as a Class B traffic violation, which carries significant penalties including:

• Fines ranging from $135 to $1,000, with a presumptive fine of $265.
• Prohibition from obtaining a driver's license for at least 180 days following conviction.
• Potential additional penalties if the driver was operating the vehicle while their license was suspended or revoked, which can include jail time and further fines.

For minors specifically, Oregon has strict graduated licensing laws, including curfews and zero tolerance for alcohol, and violations can lead to license suspension and fines. Driving without any permit or license bypasses these rules entirely and is treated as a serious offense.

Unlike some states, Oregon does not allow minors to drive legally without at least a learner’s permit. There are no exceptions for minors driving without a license or permit on public roads. Parents or guardians who knowingly allow an unlicensed minor to drive could also face legal consequences, although this is more explicitly noted in other states' laws.

In summary, a minor caught driving without a license or permit in Oregon faces fines, a delay in eligibility for licensing, and possibly other penalties such as probation or jail time depending on the circumstances. The law aims to enforce safe driving practices and ensure minors comply with graduated licensing requirements before driving independently.
