Digi Tachograph newbie

Hi guys

I’m a newly qualifed hgv driver and im starting a new job on Monday and I’m alittle nervous on using the digi tacho. Are there any good pointers any of you experienced drivers could give me.

Also going on to something different, the maximum 90hrs over 2 weeks is that driving hours or working hours?

Thanks guys

90 hours is driving hours. As for pointers, you can run a search on the net for tacho simulators, also some videos on YouTube
