I'm glad you chimed in when you did Stephen with a bit of sound, common sense.
The people who bleat about VOSA officers are probably the same people who in the next breath bleat about "there never being enough cops on the beat".
There are too many people on the road driving appalling maintained cars and lorries - no lights, illegal tyres, brake lights flashing as indicators (!), buckled wheels, and yes, badly loaded caravans, etc. (And that's just the defects that are obvious!)
We don't need fully and expensively trained police officers to deal with such matters, nor the aftermath of accidents. Let these officers (specialists in their own field) deal with them and let the real policemen get on with more important stuff.
If your car is legal, you have nothing to worry about. If it isn't, then I for one hope police, or a VOSA officer, stop you (whether it delays your holiday or not...)
Roll on the day when they are introduced on ALL roads...
