Which of the following is a true statement about transporting firearms in a vehicle in Indiana?

Transporting firearms in a vehicle in Indiana is governed by specific regulations to ensure safety and compliance with the law. The requirement for the firearm to be unloaded and locked in the trunk reinforces these principles, as this method reduces the risk of accidents and unauthorized access during transport. Storing the firearm in the trunk when traveling helps to meet legal standards and promotes responsible firearm ownership, aligning with best practices for firearm safety.

The other options reflect variations in transport methods that may not adhere to Indiana law. For instance, keeping a loaded firearm on the passenger seat or making it visible could pose safety risks and are not compliant with the state's transportation requirements, which emphasize secure and careful handling of firearms.
