Even if you are driving under the posted speed limit, you may be given a ticket or citation for driving too fast for the conditions. Driving too fast for conditions is defined as traveling at a speed that is greater than a reasonable standard for safe driving.
Examples of conditions where drivers may find themselves driving too fast include wet roadways (rain, snow, or ice); reduced visibility (fog); uneven roads; construction zones; curves; intersections; gravel roads; and heavy traffic.
In South Dakota, as in many states, it is possible to receive a ticket for driving too fast for conditions, even if you are driving at or below the posted speed limit. State law recognizes that certain conditions require drivers to adjust their speed for safety. According to South Dakota Codified Laws (SDCL) 32-25-7, no person shall drive a vehicle on a highway at a speed greater than is reasonable and prudent under the conditions, having regard to the actual and potential hazards then existing. This means that in adverse conditions such as rain, snow, ice, fog, construction zones, or heavy traffic, drivers are expected to drive at a speed that ensures the safety of themselves, their passengers, and other road users. Failure to adjust speed to these conditions can result in a citation for driving too fast for conditions, which is considered a misdemeanor offense under South Dakota law.
