American truck drivers are'nt the same as 'lorry drivers'. If you can find the drivers lounge at truck stops sometimes you can 'talk it up' with drivers over such topics as sports or how do they like the job etc while watching TV. They will let you know if they're looking. At rest areas it's best to let them come to you either in the toilets or at a picnic table. I don't know about the 'interior lights-on' because they are on break and could be doing thier logbook or something. Obviously the eyes have it.
Sadly pimps will offer the services of underage girls (and maybe boys) at the major truckstops as we've read in news reports.
