6. When the main driver is down as a “named” driver
We all know how beneficial long no-claims bonus and similar can be when you have to cut down on your insurance cost. Thanks to that many people decide to put that sort of driver down as the main driver, while someone else (without these benefits) is an “occasional driver.” This is, of course, also a bad thing that is flat-out illegal and if you get caught for what they call “fronting” you immediately get your policy canceled, plus points on your license and a hefty fine.
