yes, check that radiator cap, as most modern ones feel like they fit but after a few miles and warming up, they start letting coolant out the overflow tube and onto the road.

If you suspect a head gasket leak and it's not in the oil nor burning white exhaust/coolant leaking out exhaust pipes, then it can only be combustion gasses into the coolant and pressurizing the system and pushing the coolant out the overflow.

Napa has a kit for like $40 that has blue fluid and tests for this. If it's happening, the fluid in the kit will turn from blue to green if anything like that is happening.
