Radio signals have no mass so why don’t they go faster than light?

Light (or any electromagnetic radiation) has no mass. That's why it can only move with the speed of light.

Radio and light are both parts of the E-M spectrum, the same thing(electromagnetic radiation) , but with different wavelengths. So they both propagate (travel) at the speed of light (in a vacuum).

The answer may be just quiet acceptance of the facts.

The speed is the property of the medium which is vacuum. Like sound velocity depends on the back ground pressure and density. No field can travel faster than velocity of light. Radio signals contain electric and magnetic field vibration. Therefore, they can not go faster than C.

Because radio signals and light travel at exactly the same speed because they are exactly the same thing: electromagnetic radiation

Because it is not an issue of mass. It is an issue of energy.

Radio signals are light, just a longer wavelength than visible light.
All massless particles and waves go at the speed of light. Nothing goes faster.

Because they are just a different frequency of light. Radio signals and visible light are both a part of the EM spectrum. The only difference is the frequency.

They go as fast as they can.
