What are the required lights on the front of second division or combination vehicles over 25 feet long or wider than 80 inches?

The requirements for lights on the front of second division or combination vehicles that are over 25 feet long or wider than 80 inches specify that these vehicles must be equipped with two yellow or amber lights positioned on each upper-front corner. This is an essential safety feature, as it enhances visibility and allows other drivers to easily identify the size and presence of larger vehicles, particularly in low-light conditions or adverse weather.

The presence of these upper-front corner lights helps to indicate the vehicle's width and to alert surrounding traffic to its potential movements. This is particularly important for large vehicles that may not be as easily visible as smaller ones. The use of yellow or amber lights is standard practice, as these colors are universally recognized as cautionary signals on the road.

In contrast, other lighting options mentioned do not meet the specific requirements for larger vehicles. For instance, red lights are typically reserved for indicating stop or warning signals rather than for general visibility, and single lights do not provide the necessary coverage to signal the size and position of the vehicle effectively.
