Tachograph analysis
- Driving left before a break is due
- 0.5
- Driving left today
- 5
- Driving left this week
- 18
- Breaks the day will need at this rate

Every figure on this site comes from the numbers you enter and the method printed beside them: your hours, your limits, your break length, your download interval. Where a guide names a published document it names the document and the date it was read. This site publishes no regulation text, no legal advice and no analysis bureau's price.
The figures shown are a worked example for one driver's day: 0.5. Change them for yours.

A drivers' hours check is the arithmetic a transport office does in its head twenty times a day and gets wrong when the day is busy. This one takes the hours a driver has actually done, the hours since their last break, the hours driven this week and the days since their last weekly rest, together with the limits your operation works to, and returns the driving left before a break falls due, the driving left today and this week, the breaks and break minutes the day will need, and the spread once those breaks are counted. The limits are yours to enter: this site publishes no regulation, and the defaults are the usual figures rather than a statement of the law.
Where the constants in this tool come from
GOV.UK, Drivers' hours, the guidance a GB operator's regime is built against.
What a transport manager asks before running the Tachograph analysis
What are the drivers' hours limits?
GOV.UK's drivers' hours guidance is where they are set out, and this site does not restate them as its own. The sheet takes the limits your operation works to as inputs, with the usual figures as defaults, so an extended day or a domestic rule set is a change of input rather than a different tool.
Does this replace analysis of the cards?
No. This is the forward-looking check on a day in progress. Analysis is what happens to a downloaded card afterwards, and the record of it is what an investigation asks for.
Can I use it for a whole week?
It works a day and a week at once: driving left today, driving left this week, and days until a weekly rest is due. It is deliberately not a planning tool for a whole roster, which is a different job.
Why do the break minutes matter?
Because a day is not the driving limit, it is the driving plus the breaks, and offices that plan on driving alone find the spread runs past what the shift allows. The sheet prints both.
