Small Propane Tanks Can You Store The Small 1lb Propane Tanks For Gas Grills In Your Trunk Overnight?

Can you store the small 1lb propane tanks for gas grills in your trunk overnight? - small propane tanks

I switch from coal to gas and planning a tailgate party in the next month. Saturday morning tailgating starts, but came on Friday evening and stay in a nearby hotel, so I wonder if you can the tank in the boot on Friday night, or what is the best option to keep. Each tailgating / grilling and propane experts out there?
