Radar warning devices (radar wave detection devices, radar detectors, driver-alert systems, etc.) alert vehicle drivers via acoustic or optical signals to police speed traps. These signals allow drivers who are driving too fast to reduce their speed in time before they reach the speed trap.
In Switzerland it is prohibited to use devices of this nature as well as to place them on the market.
Devices of this nature will be confiscated and will be handed over to the responsible cantonal authorities. As a rule, the device will be destroyed and a fine will be imposed.
If the device was not declared or incorrectly declared for customs clearance, this will lead to an additional fine.
The Federal Roads Office (FEDRO) can provide you with information on the permissibility of individual device types.
