The maximum fine for a conviction of driving without a valid driver license varies by country and circumstances:

• In Germany, driving without a valid license under § 21 StVG can result in a fine of up to 180 daily rates or imprisonment for up to one year. The exact fine depends on the daily rate calculation based on the offender's income, but it can be substantial. Intentional offenses lead to harsher penalties than negligent ones

• In the UK, the maximum fine for driving without a valid license is £1,000. Additional penalties can include discretionary disqualification and between three and six penalty points on the driving record

• In the US (Texas example), the maximum fine for a first offense of driving without a license is $200. More serious cases, such as causing injury or having prior offenses, can lead to fines up to $4,000 and possible jail time

• In Poland, the fine for driving without a license can be up to PLN 5,000, along with a driving ban

In summary, the maximum fine can range from hundreds to thousands of the local currency, with additional penalties such as imprisonment or driving bans depending on the jurisdiction and severity of the offense. For example, in Germany, the fine can be very high due to the daily rate system, and imprisonment is also possible. In the UK, the maximum fine is £1,000. In the US, fines vary by state but can reach several thousand dollars in aggravated cases. Thus, the maximum fine for driving without a valid license is jurisdiction-dependent but can be as high as a year’s worth of daily income rates in Germany or £1,000 in the UK.
