wtd break

wolves:
When I took 30min wtd break it only showed as 15 min break recorded on tacho, but on printout and tachomaster it shows 32 mins. why is this ?

It counted as a 15 min driving time break which is what the tacho is designed to look for

Companies keep a check on WTD not authorities (they not bothered) so the analysis company will look at that as 32 mins for WTD
