All cars and trucks must have a minimum of two brake systems to ensure safe and reliable stopping capabilities. This requirement is in place to enhance the vehicle's safety for the driver, passengers, and others on the road.

Having two brake systems typically refers to the primary brake system operated by the foot pedal and a secondary system, which can be a backup that ensures the vehicle can still be stopped in case the primary system fails. This dual-braking system is crucial for preventing accidents that could arise from brake failure.

The presence of two brake systems is a standard safety feature mandated by regulations, reflecting the necessity for redundancy in critical systems of vehicles. This helps to maximize control over braking, especially in emergency situations where effective stopping power is vital.
