What is the basic rule regarding speed limits?

The fundamental rule regarding speed limits is to not exceed the posted limit and to adjust your speed based on driving conditions. This principle is essential for maintaining safety on the roads. Speed limits are established to provide a guideline for safe driving speeds under normal conditions, but various factors such as weather, road conditions, traffic, and visibility can necessitate lower speeds to ensure safety.

For instance, in inclement weather like rain, fog, or snow, or in situations involving heavy traffic or road work, it becomes critical to drive slower than the posted limit to accommodate for reduced visibility and longer stopping distances. Adjusting your speed appropriately in response to your environment helps protect not only you but also other road users.

The other options suggest behaviors not aligned with safe driving practices, such as exceeding limits without considering safety or following the pace of surrounding traffic without due regard for posted speeds. It is important to prioritize adherence to speed laws while also being adaptable to the conditions on the road.
