Federal Laws Governing The Use Of Radar Detectors 

It is not against federal law to receive radar transmissions with your Cobra radar/
laser detector. The Communications Act of 1924 guarantees your right to receive 
radio transmissions on any frequency. Local laws that contravene this Act, while 
illegal, may be enforced by your local law enforcement officials until and unless 
they are prohibited from doing so by federal court action.

Safety Alert

Use of this product is not intended to, and does not, ensure that motorists or
passengers will not be involved in traffic accidents. It is only intended to alert 
the motorist that an emergency vehicle equipped with a Cobra Safety Alert 
transmitter is within range as defined by that product. Please call local fire 
and police departments to learn if coverage exists in your area.

Safe Driving 

Motorists, as well as operators of emergency or service vehicles, are expected to
exercise all due caution while using this product, and to obey all applicable traffic laws.

Security Of Your Vehicle 

Before leaving your vehicle, always remember to conceal your radar detector 
in order to reduce the possibility of break-in and theft.
