How many tail lamps must a motor vehicle or trailer have?

A motor vehicle or trailer must be equipped with two tail lamps. This requirement is established to ensure visibility and safety on the road. Having two tail lamps enhances the likelihood that they will be seen by other drivers, even if one lamp fails. The placement of these lamps at the rear of the vehicle helps to indicate its presence, direction, and status to vehicles traveling behind.

While one tail lamp could theoretically provide some level of visibility, it significantly reduces safety in low-light conditions or adverse weather. The two-lamp system works effectively to minimize the risk of accidents due to decreased visibility. Additionally, compliance with this regulation ensures that vehicles meet legal standards set forth in Indiana traffic laws regarding vehicle equipment. In summary, two tail lamps are essential for safety and legal compliance.
