Classification leadership table
In the 2018 Istrian Spring Trophy, three different jerseys were awarded for the main classifications. For the general classification, calculated by adding each cyclist's finishing times on each stage, the leader received a yellow jersey. This classification was considered the most important of the 2018 Istrian Spring Trophy, and the winner of the classification was considered the winner of the race.

Additionally, there was a points classification, which awarded a blue jersey. In the points classification, cyclists received points for finishing in the top 3 in each intermediate sprint. For winning an intermediate sprint, a rider earned 5 points, with 3 for second and 1 for third. There was also a mountains classification, the leadership of which was marked by a green jersey. In the mountains classification, points were won by reaching the top of a climb before other cyclists, with more points available for the higher-categorised climbs.
