The low air pressure warning system (red light and buzzer) will activate when the psi drops below:

A. 60 psi
B. 100 psi
C. 40 psi
D. 20 psi

Answer :

Final answer:

The low air pressure warning system in a vehicle activates when the tire pressure drops below 60 psi, to alert the driver of the potential safety issue.

Explanation:

The low air pressure warning system in a vehicle is designed to alert the driver when a pre-set pressure threshold is reached, indicating that the air pressure in a tire has fallen to a potentially unsafe level. This safety feature employs both a red light and a buzzer to get the driver's immediate attention. According to standards and regulations, this low air pressure warning system is typically set to activate when the air pressure in the tires drops below 60 psi. This is the critical threshold to ensure enough time for the driver to safely address the issue before the tire pressure becomes dangerously low.
