What is the minimum number of brake lights required on the rear of a motor vehicle?

In Indiana, as in many other states, the law requires that vehicles must be equipped with a minimum of two brake lights on the rear. This requirement is designed to enhance safety on the road by ensuring that other drivers can easily see when a vehicle is braking, which helps prevent rear-end collisions.

Having two brake lights allows for better visibility from both sides of the vehicle, reducing the chance that a driver will miss the indication that a vehicle is slowing down or stopping. Additionally, having two lights provides a redundancy in case one should fail; the vehicle would still have a functioning brake light to alert other drivers. This regulation is in place to enhance overall roadway safety and is standard in many regions across the United States.

Options that suggest fewer than two brake lights would not provide the same level of safety or visibility, and the requirements set by traffic law reflect the importance of visibility and communication between drivers on the road.
