Hello, I've heard of some odd laws out there that drivers can get tickets for like in Mass you need to pass someone in 3 minutes and in CA you need to have a line in your log every 4 hours.

I'm a new driver and was wondering how can someone find out about all of these odd - not so obvious laws out there - I don't want to get tickets out of just not knowing.....

Thanks

Have never heard either of those "Laws". Of course..I have never driven a truck in MA..and don't have any intention of doing so anytime soon. As for CA....

Nothing there about a line every 4 hours. As with Federal Regulations, you must keep your logbook up, to the last change of duty status.
