Problems at pump as more people take road trips on Fourth of July weekend

A shortage of truck drivers is causing gasoline delivery delays, leaving some stations with low or no gas. Travelers taking road trips for the Fourth of July are advised to not let their fuel flirt too close to empty. They may have to travel to the next exit if they come upon a station without gas.
