When conditions change, driving style changes. Weather changes require you to adjust your acceleration, steering and braking.

Basic Speed Law: The basic speed law means you must drive at a speed that is always reasonable. You must adjust your speed to both actual and potential hazards. Basic speed law overrides a posted speed limit when conditions require a lower speed. This means that a police officer may stop and give you a ticket under certain circumstances – even if you were driving at the posted speed limit.
