Abstract

A system for warning a driver comprises an input interface and a warning determiner. The input interface is to receive a set of warnings, wherein a warning of the set of warnings is associated with a road segment and a set of conditions. The warning determiner is to determine that a current location matches the road segment associated with the warning and, in the event that it is determined to warn a driver based at least in part on the warning and the set of current conditions, to indicate to warn the driver
