b) false

1. __________ improve a drivers ability to identify hazards and conditions in the driving environment and even act as a warning to fellow drivers in certain situations.

c) hazard lights

Explanation:

Question 10

Airbags can sometimes be disabled by the owner (e.g., with a key or switch in some vehicles) or by the manufacturer, but not all require only manufacturer - disablement. Some vehicles have user - accessible means to disable airbags (like for child seats in certain positions). So the statement is false.

Total stopping distance is composed of reaction distance and braking distance. Reaction distance is proportional to speed ($d_{reaction}=v\times t_{reaction}$), and braking distance is proportional to the square of speed ($d_{braking}=\frac{v^{2}}{2a}$). Reducing speed decreases both reaction and braking distances, so total stopping distance decreases. Thus the statement is false.

• Turn signals: Indicate turning or lane - changing intentions, not mainly for hazard identification or warning in general driving situations.
• Headlights: Improve visibility to identify hazards (like objects, other vehicles) in low - light conditions and also make the driver visible to others, acting as a warning.
• Hazard lights: Used to indicate a vehicle is in distress or stopped, not for general hazard identification while driving.

Headlights help the driver see the road and hazards ahead (e.g., in darkness or bad weather) and also make the vehicle visible to other drivers, warning them of its presence.

Answer:

b) False
