What period of time does one tachograph chart cover?

Explanation: Your tachograph chart is a legal document; it's a record of your work covering a rolling 24-hour period. Drivers who break the rules are subject to heavy fines and could lose their vocational licence. Altering your tachograph chart with intent to deceive is against the law and could lead to a prison sentence. Similar penalties exist for those who permit such offences.
