What does interfering with a traffic control device entail?

Interfering with a traffic control device specifically refers to actions that compromise the integrity or functionality of the device itself. This includes alteration, defacement, or removal of a sign, which directly impacts its purpose and can lead to increased risks on the roadway. Such actions can confuse drivers, create hazardous situations, and undermine public safety.

The other options, while related to traffic regulations, do not specifically capture the essence of interfering with a traffic control device. Failing to follow traffic signals is a matter of compliance with the rules established by those devices, rather than an act of interference. Blocking a traffic sign refers to obstructing its visibility, which is a concern but again, does not involve changing or damaging the sign itself. Driving without a traffic permit deals with licensing and vehicle legality, which, while important, is unrelated to the concept of interference with traffic control devices. Hence, the focus on altering, defacing, or removing a sign aligns perfectly with the definition of interference.
