Drivers should maintain a safe and reduced speed when passing or approaching tow trucks on an undivided highway. Option B is incorrect because it may not always be safe to maintain the posted speed limit when passing tow trucks. Option C is incorrect because it is too slow and may impede traffic flow. Option D is incorrect because there is a specified speed that drivers should follow and failure to do so could result in a traffic violation or potential safety hazard. Option A is the most appropriate answer as it suggests a moderate and safe speed to pass tow trucks on undivided highways.
