À
ect radio waves effectively, such as
an unloaded trailer or an automobile with a loading platform covered by a soft top,
vehicles with a hard plastic tailgate, and round-shaped vehicles.
y
Vehicles ahead with low vehicle height and thus less area for re
À
ecting radio waves.
y
Visibility is reduced due to a vehicle ahead casting off water, snow, or sand from its
tires and onto your windshield.

The trunk/luggage compartment is loaded with heavy objects or the rear passenger
seats are occupied.

When driving on roads with little traf

c and few vehicles ahead or obstructions for the
