View radar on your bike computer:

The vehicle position moves up the column as a vehicle gets closer to your bike. The threat level changes color based on the potential level of threat.
Green indicates no vehicle is detected. Orange indicates a vehicle is approaching. Red indicates a vehicle is approaching at a high rate of speed.
If your bike computer is set to sound or vibrate, it will sound an alarm when it detects the first vehicle. After the threat is eliminated and a new approaching vehicle is detected, the computer will sound an alarm again.
