Question: 1 / 400

If a car has a break issue, which color exterior light will illuminate?

Red

Yellow

Blue

When a car has a brake issue, the appropriate exterior light that typically illuminates is a red light. The red light serves as an indicator of a serious issue related to the brake system. Red lights are commonly used in vehicle signaling to convey urgent problems that demand immediate attention from the driver.

While yellow lights can indicate caution and alert drivers to potential issues, they do not signify an immediate emergency like a brake failure does. Blue lights are usually reserved for police or emergency vehicles, and green lights typically indicate operational functionality or signaling that something is working properly.

Thus, when it comes to brake issues specifically, the illumination of a red light is the standard that clearly alerts the driver to take action, making it essential safety information for anyone operating a vehicle.
