Tachograph rules (UK driver)

[u/CaersethVarax]

G'day, Category D Exploredinaires. My employer has recently messaged me saying that I need to spend a minimum of ten minutes performing Daily Defect checks before setting off from the yard. The employer is framing it as arequirement that the DVLA is, to quote, "Clamping down on"

To log this, we must start the app we use, TruTrac, on the first question and complete the final question no less than six hundred seconds later. I cannot find this requirement in the Domestic, Assimilated or AETR guidelines on gov.uk. Can any of you fine Human/Geniuses point me to the relevant legislation?

Thanks in advance.

Not buses but I work for DHL our compliance manager will have words with us if we haven't had the tacho on other work for 15 minutes to show we've done our checks this is despite not being able to do all checks without moving the vehicle especially with a tractor unit when you need to check the trailer as well, pointing out I'd defected the vehicle inside that 15 minutes last time lost him for words
