Always be aware of the local maximum speed. Max Speeds keeps the speed limit visible and becomes a welcome addition to your dashboard. It will warn you subtly when you are speeding. You will find that you will become less tired from driving if you don't have to keep remembering the maximum speed, but see it on your dashboard.

Max Speed uses maximum speed data from OpenStreetMap, the Wikipedia of maps worldwide. If you enjoy using Max Speed, please consider helping out by making map improvements in OpenStreetMap (Google for 'OSM contribute').
