A "driver debrief" is a conversation about a driving or rest-time rule a driver broke. It explains what happened and why it matters. The driver signs to show they understood. The person who gave the debrief signs too.
EU rules (Regulation (EC) No. 561/2006) say a driver must keep to the driving and rest-time limits. Breaking them can lead to fines for both the driver and the employer during a roadside or company check. A debrief shows that a company dealt with a broken rule and made sure the driver understood it. This helps stop the same thing from happening again.
A debrief is not the same as an infringement. An infringement is simply a broken rule. Tachogram works this out from the driver's tachograph data. A debrief is the conversation that happens afterward. The driver signs it to show the conversation happened.
A signed debrief is useful later, too. If the same kind of rule-breaking happens again, it shows the company already talked to the driver about it. If a roadside check or an audit needs proof, the signed debrief shows exactly when the conversation happened and that the driver understood the rule.
Tachogram keeps a dated note of every debrief for you, so it's always there when you need it.
