When approaching a solid yellow traffic light, a driver should slow down and prepare to stop if it is safe to do so. If it is not safe to stop, the driver should proceed with caution through the intersection.
After a solid amber traffic light, the light typically turns red. The amber light serves as a warning that the signal is about to change, urging drivers to prepare to stop if it's safe to do so. In some jurisdictions, drivers may proceed through an amber light if they are already in the intersection or cannot stop safely. However, running a red light is generally considered a traffic violation.
Light travels faster through liquid than through solid. The speed of light in a medium is determined by the refractive index of the material, which is lower in liquid compared to solid materials.
You can proceed straight ahead or make a right turn when you have a solid green light while driving. Make sure to yield to pedestrians and oncoming traffic if you are turning.
A solid yellow light typically indicates that a traffic signal is about to change to red, prompting drivers to slow down and prepare to stop. It serves as a warning to proceed with caution and be prepared to come to a stop if necessary.
You stop on green when the conditions are unsafe to proceed. Just because the light is green doesn't mean that you have an unobstructed path in which to drive. You never proceed on a solid red light unless instructed to do so by a police officer. A blinking red light means to stop and proceed when it is safe to do so ... just like a stop sign.

solid matter
Light travels slower through a solid because it interacts with the atoms and molecules within the solid, causing it to be absorbed and re-emitted multiple times as it moves through the material. This interaction leads to a decrease in the speed of light compared to its speed in a vacuum.
The light wave will interact with the atoms and molecules in the solid, causing them to vibrate and re-emit the light wave in different directions. The speed of light in a solid is slower than in a vacuum due to these interactions.
Solid objects, such as walls or metal barriers, are examples of things that light cannot pass through. When light encounters a solid object, it gets absorbed, reflected, or refracted, causing it to not pass through.
When you encounter a solid yellow light while driving, you should slow down and prepare to stop, unless it is unsafe to do so. The yellow light indicates that the signal is about to turn red, so proceed with caution and be prepared to stop if necessary.
