b) Braking Devices
c) Ignition Interlocks
d) Mirrors

Answer :

Final answer:

Devices installed in cars to measure alcohol on the driver's breath are called Ignition Interlocks. Correct option is C.

Explanation:

Devices installed in cars that measure alcohol on the driver's breath are called Ignition Interlocks. These devices prevent the car from starting if the driver's breath alcohol concentration is above a preset limit, thereby enhancing road safety.

The working principle of ignition interlocks is based on the fact that alcohol in the blood evaporates into the lungs and is exhaled. The device then measures the concentration of alcohol in the exhaled air, which is directly proportional to the blood alcohol level.

This mechanism aims to deter driving under the influence of alcohol and is a critical health and safety feature in vehicles.There are discussions about enhancing safety features in vehicles, especially with the advent of self-driving cars and electric vehicles.

Making cars inoperable if a driver is detected to have consumed excessive alcohol is a proposed feature aimed at preventing accidents and promoting public health.Other potential safety features might include advanced driver-assistance systems (ADAS), emergency braking, and pedestrian detection systems.
