A number of state transportation agencies have begun offering motorists up-to-the-minute traffic updates on Twitter.
Just be careful that you don't check them while behind the wheel, because you could end up with a ticket.
At least 22 states ban texting while driving, but also offer some type of service providing information about traffic jams, emergencies and other road conditions.
Safety experts and some politicians are calling that a dangerous mixed signal.
Minnesota lawmaker Frank Hornstein says, "You shouldn't be fiddling around with any kind of electronic gadget in your car while driving."
State transportation officials insist they are not encouraging people to get online while driving.
Rather, they say drivers should check their tweets before getting on the road.
