<p>Dear Mr. / Miss / Mrs. {vehicleInfo.OwnerName},</p>
<p>We hereby inform you of the fact that a speeding violation was detected with a
vehicle that is registered to you.</p>
<p>The violation was detected by a speeding camera. We have a digital image of your
vehicle committing the violation on record in our system. If requested by your
solicitor, we will provide this image to you.</p>
<hr/>
<p>Below you can find all the details of the violation.</p>
<p>
<b>Vehicle information:</b>
<table>
<tr><th>License number</th><td>{vehicleInfo.VehicleId}</td></tr>
<tr><th>Brand</th><td>{vehicleInfo.Brand}</td></tr>
<tr><th>Model</th><td>{vehicleInfo.Model}</td></tr>

</p>
<p>
<b>Conditions during the violation:</b>
<table>
<tr><th>Road</th><td>{speedingViolation.RoadId}</td></tr>
<tr><th>Date</th><td>{speedingViolation.Timestamp.ToString("dd-MM-yyyy")}</td></tr>
<tr><th>Time of day</th><td>{speedingViolation.Timestamp.ToString("hh:mm:ss")}</td></tr>

</p>
<hr/>
<p><b>Sanction handling:</b></p>
<p>If the amount of the fine is to be determined by the prosecutor, you will receive a notice
to appear in court shortly.</p>

email. If you fail to pay within 8 weeks, you will receive a first reminder email and <b>the
fine will be increased to 1.5x the original fine amount</b>. If you fail to pay within 8 weeks
after the first reminder, you will receive a second and last reminder email and <b>the fine
will be increased to 3x the original fine amount</b>. If you fail to pay within 8 weeks
after the second reminder, the case is turned over to the prosecutor and you will receive a
