Must you always drive at the speed limit?

Driving at the speed limit is generally mandated; however, road conditions, traffic, weather, and visibility can necessitate a reduction in speed for safety. The correct response acknowledges that while the posted speed limit indicates the maximum safe speed under ideal conditions, it is crucial for drivers to assess their surroundings. For example, if the roads are wet from rain or there is heavy fog, driving slower than the speed limit is necessary to maintain control of the vehicle and to ensure the safety of all road users. This adaptability to conditions is a key principle in defensive driving, emphasizing that safety should always take precedence over strictly adhering to speed limits.
