Can a car or pickup truck have three stoplights?

A car or pickup truck can indeed have three stoplights, with one positioned in the middle. This setup enhances visibility for drivers behind the vehicle, especially in situations where a vehicle is larger or has a cargo bed that might obstruct the standard rear lights. The middle stoplight, often referred to as a third brake light, is typically located higher up on the vehicle, making it particularly effective at alerting drivers of its braking action.

This configuration is not only permissible but is also a common feature in many modern vehicles as a safety measure. By having this extra light, it can reduce the chances of rear-end collisions by ensuring that following drivers have clear and early warnings of braking. The focus on visibility and safety is the main reason why this design is encouraged and allowed in automotive regulations.
