Final answer:
A motorist should always maintain a safe following distance in poor conditions.
Step-by-step explanation:
When driving in poor conditions, such as bad weather or low visibility, it is essential for a motorist to maintain a safe following distance. This means keeping a significant gap between your vehicle and the vehicle ahead of you to allow for ample braking distance and reaction time. In poor conditions, it is recommended to maintain a following distance of at least four seconds.
