One or more computer-readable media having computer-usable instructions stored thereon for performing a method of warning a driver of changing road conditions, the method comprising: retrieving information associated with a road on which a vehicle will be traveling at a future time;determining, using a processor, whether a first limitation associated with the road on which the vehicle will be traveling is different from a second limitation associated with the road on which the vehicle is currently traveling;determining that the vehicle is within a distance threshold of the first limitation, the distance threshold associated with the first limitation; andbroadcasting a warning to a driver of the vehicle in response to determining that the first limitation associated with the road on which the vehicle will be traveling is different from the second limitation associated with the road on which the vehicle is currently traveling and the vehicle is within the distance threshold of the first limitation. 22. The media of claim 21, wherein the first limitation associated with the road on which the vehicle will be traveling is a first posted speed limit; and wherein the second limitation associated with the road on which the vehicle is currently traveling is a second posted speed limit. 23. The media of claim 21, wherein the first limitation associated with the road on which the vehicle will be traveling is a first number of available lanes; and wherein a second limitation associated with the road on which the vehicle is currently traveling is a second number of available lanes. 24. The media of claim 21, wherein retrieving information associated with the road on which the vehicle will be traveling further comprises: requesting information associated with the road from a device that is remote from the vehicle. 25.
