What is a requirement regarding brakes on a vehicle in Indiana?

In Indiana, it is a requirement for vehicles to be equipped with brakes that operate on at least two separate wheels. This regulation is in place to ensure that a vehicle can be safely brought to a stop under various driving conditions. Having brakes on two wheels provides a backup in case one of the braking systems fails, thereby enhancing safety for the driver, passengers, and other road users. This requirement helps to prevent accidents that could arise from brake failure, ensuring that vehicles are capable of being controlled effectively at all times.

The other options do not meet the necessary safety standards outlined in Indiana traffic laws. For example, having only manual brakes or just one braking method would compromise vehicle safety, and the idea of having no brakes at all is obviously impractical for safe vehicle operation.
