How are drivers sorted/ranked in the "Categories" tab?

In the "Categories" tab, you can view a histogram that represents the weekly evolution of driver categories. This is to ensure that the number of good drivers is increasing.

A driver's category is determined according to his or her average eco-driving score over the week. There are four categories:

• Inactive: the driver has no score because he/she has not made any trip during the week;
• To monitor: the driver's average score is less than 7.5/10;
• Good: the driver's average score is between 7.5/10 and 8.5/10;
• Excellent: the driver's average score is higher than 8.5/10.

It is possible to adjust the display period of the histogram:

• for the last three months,
• for the last six months,
• in the last 12 months,
• in the current year,
• in the previous year,
• or since the creation of the account.
