FAQ
How close are the times?
They are estimates from available traffic data. Traffic can change quickly, so use Green Light as a planning guide and leave extra room for important trips.
What do the colors mean?
The shortest option is marked as best. Green is within about 10% of that time, yellow is up to about 50% longer, and red is anything slower.
Where is my route stored?
Recent routes are stored browser-local in this browser so you can reuse addresses. Green Light does not use accounts or server-side route history in the beta.
How do I send feedback?
Use with what route you were trying, what you expected, and what happened.
Can I plan another day?
Yes, choose a future date and time window. The beta supports limited time windows.
