Final answer:
The minimum allowable level of aftermarket tinting for windows in the rear according to New Hampshire regulations is 35% visible light transmission (VLT).
Step-by-step explanation:
The minimum allowable level of aftermarket tinting for windows in the rear according to New Hampshire regulations is 35% visible light transmission (VLT). VLT refers to the amount of light that is allowed to pass through the tinted window. A lower VLT means less light transmission.
For example, if the window has a VLT of 35%, it means that only 35% of the visible light can pass through the window, while the remaining 65% is blocked. This level of tinting provides privacy and blocks a significant amount of sunlight, but still allows for sufficient visibility from inside the vehicle.
It's important to note that different states may have variations in their tinting regulations, so it's always advisable to check the specific regulations of the state you are in.
