While certain laws in the U.S. are federal, others are defined at the state level. Motor vehicle operation is governed by state law.
This means that drivers’ rules on the road differ from state to state. When visiting states outside your home state, for example during a road trip with a rented car, it is essential to have a high-level understanding of local driving laws.
When driving in a new place, you are likely consumed with figuring out your way and adapting to the local driving style.
The last thing you need is to get pulled over by the police for violating a local traffic regulation! If you are pulled over, keep in mind the following:
- It is ok to ask questions about local regulations and explain that you are from another state, but you may still have to pay the ticket.
- Your vehicle may need a vehicle history report to confirm that it was not lost or stolen (rental cars have it).
- It is your responsibility to be aware of local laws, even if you are from another state.
It is impossible to be aware of every motor vehicle law for every one of the fifty United States, but exploring the below categories can help you better understand the big ones.

Speed Limit Laws in U.S. States | Rented Cars
Speeding is one of the most common reasons drivers are pulled over. Speed limits vary widely by state, so paying attention to signage is very important.
Depending on zone type, many states will have standard speed limits, such as twenty miles per hour in a school zone, sixty-five miles per hour on the highway, or thirty miles per hour in a residential area.
The longer you drive in one state, the more you will get used to these standard zone limits.
States with higher populations and more city space will usually have stricter speed limit laws than rural states with lots of space.
