Customers who use the hosted version of Geotab have access to real world posted road
speeds. This allows street level accurate notifications to be sent when driver’s exceed
local speed limits. Posted speed limit data comes from two sources:
●
NAVTEQ Maps
●
Open Street Maps (OSM)
Note: Posted road speed is only available to customers who use the hosted version of Geotab and
is supported in the U.S. and Canada.
Posted road speeds can change frequently and may contain inaccuracies. You can update
the posted road speed of any road by clicking on a road from the live map. A menu will
appear, select
Update posted road speed
to change the value.
Geotab shares the changes you make to posted road speeds with all customers. That
way, everyone benefits from each others changes. On a monthly basis, Geotab will send
the latest posted road speeds to OpenStreetMaps, where they will make them available
to everyone else on the Internet.
Note: Due to the possible inaccuracies caused by road construction or other hazards. We
recommend that posted speed limits be used as part of a larger safety strategy.

Vehicle acceleration
Geotab offers the ability to set exception rules for excessive driving behaviors such as
harsh acceleration, harsh braking and harsh cornering. Depending on the type of vehicle
the rule is applied to, use the table below as a guideline for the average g-force exertions
typical to that vehicle. In most cases, the default values found in Geotab are suitable, but
are highly customizable.
