Over by 1 minute

The DVSAs latest software actively looks for these ‘unrecorded’ movements within a break or rest period, you may think you’ve got away with it as the tacho still records the break, but you’re risking getting busted if stopped

Drive 4.5
45 min break with a small ‘unrecorded’ movement
Drive 4 5

You’ve just driven 9 hours without a qualified break!
15m - 1h over = £100
1 - 2 = £200
2+ = £300

Technically once you hit 4:30 your only option is break, but on a 2nd gen onwards October 2011+
Wait for the clock to tick onto the next minute, time 31 seconds, you can now drive for 58 seconds, do this starting and finishing on other work for 31 seconds though and it won’t add any time to the driving time
