Can VPN be tracked by government?

I'm curious about the potential for government surveillance when using a VPN. Could you explain how, if at all, the government might be able to track or monitor my activities while I'm using a VPN service? Are there any specific factors that might make it easier or harder for the government to track me through a VPN? Additionally, are there any best practices or recommendations I should follow to ensure my privacy and security while using a VPN?
