In situations where conditions are not ideal—such as wet or slippery roads, reduced visibility, or other adverse circumstances—it is important to drive slower than the posted speed limit. This precaution ensures that you have ample control of your vehicle and can respond appropriately to potential hazards. Legal speed limits are designed for optimal conditions; thus, adapting your speed to the immediacy of the environment is essential for maintaining safety. You can be ticketed for driving at an unsafe speed, even if it's within the legal limit, if the conditions warrant more caution.
