Who is responsible for obeying Indiana traffic laws while operating a vehicle?

The correct answer emphasizes that all motorists, regardless of their residency status, are obligated to adhere to Indiana traffic laws while operating a vehicle within the state. This includes both residents of Indiana and out-of-state drivers, acknowledging that traffic laws are put in place for the safety and well-being of everyone on the roadway.

When drivers enter Indiana, they are expected to comply with local regulations even if they are not residents or not registered in the state. This rule ensures that everyone driving on Indiana roads is subject to the same laws, fostering consistency and safety.

The other options suggest limitations on who must comply with the laws, such as only residents or only commercial drivers, discounting the importance of road safety for all individuals traveling through the state. Traffic laws are designed to be universal in application to ensure the safety of all road users.
