6) Restriction Symbols
When driving in truck mode, a “restriction symbol” may occasionally appear on the map screen.
The symbol is a warning of an impending truck restriction. The distance will count down to the
restriction. These are the types of restrictions you may encounter:
•
Truck height
•
Truck length
•
Truck width
•
Weight limit
•
Load type (for example, restrictions on hazardous materials)
Here is a sample warning:
In the above example, there is a 12.5 foot height restriction which will happen in 446 feet.
It is probably a low bridge!
You should not encounter many restriction symbols when following a route, because the
7700 PRO is designed to calculate a route that
avoids
any restrictions. However if you are just
driving without following a route, then you may encounter restriction symbols.
Here are the different symbols:
