Euro Truck Simulator 2: All about DRIVER RATING!

To increase the driver's rating, you need to pump skills / abilities, but the system has its own characteristics.
In the game, each skill can be upgraded to 6 time. So, driver rating depends on the maximum pumped skill, the more one skill is pumped, the higher the rating. The maximum driver rating in the game is 10.0. For each skill level you can get 0.833… rating. Accordingly, you need to pump 2 skills (12 skill levels), to get the driver rating 10.0.
If you distribute 12 skill points for different skills, it will be considered according to the maximum skill.
So, in and out 6 skills (ADR, Long distance, Expensive cargo, Fragile cargo, Urgent orders, Eco driving). However, in the game system they are counted as 5+1. Based on this, to increase your rating, you need to pump to the maximum 1 required skill (Eco driving) and one of 5 remaining to the maximum (to 6 level). It turns out for 1 skill you can increase your rating to 5.0.

• 1 level – 0.8
• 2 level – 1.7
• 3 level – 2.5
• 4 level – 3.3
