→‎Speeds: fixed typo
Each direction of travel on a road can have a speed set on it. Speeds drive the speedometer setting feature in the Waze app, and can alert drivers when they're exceeding the limit. Editors should be the speed limit on all roads using the best available information available.
Where variable speed limits are in use (such as digital signs or alternate speed when raining), editors should always map at the higher speed.
