During an unknown risk traffic stop, when may an officer arrest the operator of a vehicle?

An officer may arrest the operator of a vehicle during an unknown risk traffic stop under several circumstances, as outlined in the provided choices. Each situation reflects provisions of law that allow for arrest based on the severity of the offense.

When an operator is exceeding the speed limit by 30 mph, this behavior is not just a minor infraction but can be serious enough to warrant arrest, particularly if it poses a danger to public safety.

An operator found to be Operating Under the Influence presents a significant risk to themselves and others on the road, thus justifying immediate arrest to prevent potential harm and to enforce laws against impaired driving.

Furthermore, if an operator is committing any criminal offense related to Operating After Suspension, this too provides grounds for arrest. Operating a vehicle after having one's license suspended often involves a violation of the law that is treated seriously due to the implications regarding public safety and compliance with legal standards.

Since all of these situations represent valid reasons for an officer to make an arrest during a traffic stop, the most comprehensive answer encompasses all of the listed circumstances. This aligns with enforcement guidelines that prioritize safety and legal compliance on the road.
