Query.. . I`m really worried about you, Query. When I was working as a Computer Engineer, as you are now, I used to drive 35,00 miles per year. I assume you are doing this too and yet you only have a standard driving licence. (Assumed). I really would feel much safer if you had PSV and HGV Licence with the added qualifications for Flammable and Chemical loads.. .The time difference PPL/NPPL is insignificant and is a minimum anyway.. .. .Mike W
