Since Radar signals travel in a straight line, this Radar  

 

encounter potentially offers maximum warning range.  

 

Once this signal is received, the initial warning  

 

 

consists of the X, K, or Super Wideband Ka audio    

 

and visual alerts and the simultaneous illumination of  

 

one or more of the LEDs in the four-LED display. The  

 

actual number displayed will depend upon the  

 

 

strength of the signal received. As the strength of the  

 

Radar signal increases, the audio alerts become more  

 

rapid and more LEDs in the display will illuminate.    

 

Assuming the Radar signal remains uninterrupted, the  

 

audio and visual alerts will clearly indicate a “weak”   

 

signal becoming stronger as you drive closer to the   

 

Radar source. Remember, when the police Radar    

 

source is moving toward you, the Radar signal  

 

strength will increase much more rapidly than if you  

 

are approaching a stationary source.

2.  Stationary Radar aimed around a corner.

 

Under this circumstance, reaction time is considerably  

 

reduced. Since the Radar signals are transmitted  

 

across your line of travel, there is generally no signal  

 

available to receive until you are relatively close to the  

 

source. Once an alert is received, expect the strength  

 

of the signal to increase very quickly. Advanced  

 

warning in this situation may be reduced.

3.  Stationary Radar concealed by the crest of a hill  

 

 

aimed in your direction.

 

Radar signals travel in a straight line and do not pass  

 

through earth. Consequently, police Radar aimed at  

 

the crest of a steep hill cannot be received until you  

 

are at or near the top. Warning time may be minimal  

 

(as in situation #2) since a strong signal is not  

 

present until you are near the crest of the hill. At 

 

this point, you may be nearly in the police officer’s    

 

line of sight. When cresting a hill, a weak initial alert  

 

followed by very quickly by a full alert is typical. This  

 

alert pattern requires prompt attention.

4.  Moving Radar behind you, traveling in the same direction.

 

Police Radar signal transmitted from behind your    

 

vehicle can be received when reflected by objects in  

 

front of you such as large signs, bridges and trucks. As  

 

you drive, the size and configuration of these objects  

 

are constantly changing, causing the strength of any  

 

reflected Radar signal received to vary. A strong,  

 

uninterrupted alert indicates the patrol car is close  

 

behind.
