Under what circumstances may an abandoned or unplated vehicle be towed?

The correct answer pertains to the fact that specific regulations regarding abandoned or unplated vehicles allow them to be towed when they are on or near a highway. This is primarily due to safety and traffic flow concerns, as these vehicles can pose hazards to other drivers and may obstruct the roadway. Transport authorities and law enforcement have the responsibility to maintain safe travel conditions, which includes removing vehicles that are not properly registered or functioning from areas where they could introduce danger or traffic disorder.

Though circumstances like illegal parking or reports from citizens may prompt attention to a vehicle, the authority to tow abandoned or unplated vehicles is especially justified near highways where the risks are heightened. Other response scenarios such as towing during designated hours are not always considered sufficient reasons for action in terms of safety and road management.
