A method, a system and a computer program product for detecting and managing obfuscation of a road sign may be provided herein. The method may include receiving, a plurality of images from a plurality of vehicles over a time period, determining an extent of obfuscation of road sign in each of set of images. A current extent of obfuscation of the road sign is the extent of obfuscation of the road sign in most recent of the set of images. The method further includes performing a time-series analysis of extent of obfuscation of the road sign in each of set of images to determine rate at which the extent of obfuscation of road sign is increasing and determining an impending risk of failing to spot road sign, from an appropriate distance by vehicle. The method further includes providing a recommendation based on impending risk of failing to spot road sign.
