When does the law require lights on vehicles to be turned on?

The law requires lights on vehicles to be turned on between half an hour before sunset to half an hour after sunrise, as well as in low visibility conditions. This ensures that drivers can see and be seen by others in situations where visibility is compromised, such as at night or during rain, fog, or heavy snow. Using lights during these times enhances safety by making vehicles more visible to other road users, thereby reducing the likelihood of accidents.

The requirement to use lights in low visibility conditions addresses the fact that the human eye can struggle to see clearly under such circumstances, making it crucial for vehicles to illuminate their presence on the road. This practice not only aids the driver in seeing the road ahead but also helps other drivers and pedestrians notice the vehicle, contributing to overall road safety.

In contrast, only using lights during daytime or at night does not encompass the critical situations when visibility is reduced, and relying solely on these times could lead to dangerous driving conditions. Moreover, limiting the use of lights to only when it's raining disregards other important scenarios where visibility may be affected, thus underscoring the importance of the comprehensive regulation regarding vehicle lighting.
