How must tail lamps be visible?

Tail lamps must be visible from a distance of 500 feet. This requirement ensures that vehicles are adequately visible to other drivers in low-light conditions, maintaining safety on the road. The long visibility range contributes to the prevention of rear-end collisions, especially at night or during inclement weather when visibility may be reduced.

Visibility from 500 feet means that the tail lamps can be seen in a variety of driving conditions, allowing for early warnings for following vehicles. This is a critical aspect of vehicle safety regulations, and adherence to this rule is important for all drivers to ensure consistent safety standards on the road. The other distances—200, 300, and 400 feet—while providing some level of visibility, do not meet the maximum safety assurance required by Indiana law.
