Step-by-step explanation:
It is acceptable to use your cruise control only when conditions are ideal, meaning there is no heavy traffic, adverse weather, and you are fully alert. The best scenario for using cruise control is when:
- The road conditions are clear and dry.
- Traffic is light, and you're not likely to need to change speed frequently.
- Your full attention is on the road, and you're not feeling fatigued or distracted.
Using cruise control during rush hour, in heavy traffic, under adverse weather conditions, or when you are tired can be dangerous. It can prevent you from reacting quickly to unexpected situations, hence it is not advisable to engage cruise control under such circumstances.
