  • Drive on the right hand side of the road (except in the US Virgin Islands!)

  • Observe all posted speed limits.

  • Don’t drive if you are over the legal blood alcohol limit, in all states this is a blood alcohol concentration at or above 0.08 percent. Penalties vary by state, but basically, you don’t want to do it.

  • You must stop at all STOP signs (see below for more information on STOP signs).

  • You must stop for stopped school buses with flashing lights and a stop sign (more below on school buses).

  • At least the driver and front seat passenger must wear a seat-belt – see below for more on seat belts.

  • Speed limits vary by road and state, so there’s no one-size fits all answer here. Speed limits are in miles per hour, and some roads have posted minimum speed limits as well as maximum speed limits that you have to obey. Limits vary from 15mph all the way up to 85mph on one rural road in Texas.

  • The best advice is to follow all posted speed limit signs, and learn what the usual limits are for different road types and locations in the state or states you are driving in.


A county road is any road that is maintained by the local county authority, rather than the state or federal system. County roads are usually smaller, slower roads, and they have a “C” or “CR” designation, followed by a number.

They do vary in size and quality, from freeway sized right through to unpaved roads, depending on the area, traffic, and local county budget. Again, as they vary hugely in quality and size, speed limits on County Roads also vary tremendously.
