My board drifts and doesn’t go straight :(

Hi there, I’m still fairly new to skating even though I have done it on and off for a few years. I bought this board over a year ago and I’ve been out a few times on it over that time.

After a few days I find it hard to skate because of the drifting (and where I practice haha) so I always stop for a long time.

Does anyone have any ideas as to how I can fix this? I bought a skate tool and looked online, I took the truck bolts off and looked at the first bushing and they seemed okay. I tightened the trucks and loosened them but nothing changed with the drifting.

I have zero experience with this. Thank you :)
