Answer :
Final answer:
Distractions, specifically cognitive ones like using a cell phone while driving, significantly reduce a motorist's ability to effectively use the IPDE process by causing inattentional blindness.
Explanation:
The question asks: Motorists should be aware that their ability to effectively implement the IPDE (Identify, Predict, Decide, Execute) process will be reduced by a) Experience b) Age c) Weather conditions d) Distractions. The correct answer is d) Distractions. Distractions, such as using a cell phone while driving, significantly impair motorists' ability to observe and react to their environment. Studies demonstrate that cognitive distractions like cell phone conversations can lead to inattentional blindness, a lack of awareness of what is front of one's eyes, thus severely affecting the IPDE process. In contrast, factors like experience and age can actually enhance the IPDE process by providing more driving insight and maturity.
