Klacks plans routes and drivers — factoring in the GB Domestic Drivers' Hours Rules and the new tachograph requirement for light vans in cross-border traffic from July 2026.
For purely domestic transport, the Transport Act 1968 Part VI sets a maximum of 10 hours' driving time and 11 hours' duty time per day — barely possible to guarantee by hand across many drivers and routes.
From 1 July 2026, vehicles between 2.5 and 3.5 tonnes will newly require a tachograph, including a digital tachograph, for cross-border journeys (or cabotage) into the EU, Iceland, Liechtenstein, Norway or Switzerland.
Purely domestic GB transport stays under the GB Domestic Rules, while cross-border light-van journeys will additionally be subject to the tachograph requirement — working out by hand which rule applies to which route is difficult.
Klacks runs on-premise on your own infrastructure — ready in minutes via Docker.
Public holidays, surcharges and rest periods come preconfigured for your country — and you can adjust them anytime.
Klacks builds shift plans, flags conflicts and optimizes routes — with an AI assistant if you want.
From optimised routes to the new tachograph requirement — everything works together.
Klacks sequences stops in the most sensible order — short journeys, time windows met, fewer empty runs.
Klacks makes the 10-hour driving-time and 11-hour duty-time limits under the Transport Act 1968 visible at every route planning stage and warns in good time before a limit is exceeded. On request, Klacks can hard-block any breach — a new violation can then only be saved with documented supervisor approval.
Klacks distinguishes purely domestic GB transport from cross-border light-van routes that will newly require a tachograph from July 2026.
Klacks only assigns routes to drivers with the matching licence category — and warns before documents expire. On request, Klacks can fully block assignment once a required document has expired — only drivers with a valid licence can be scheduled.
Klacks runs on your own infrastructure — route and driver data stay with you, not even for the AI.
"Plan tomorrow's routes, driver Smith is off sick" is all it takes — Klacksy recalculates everything, including driving hours.
