Directionality of traffic flow by jurisdiction Countries by direction of road traffic, c. 2020 ⇅ Left-hand traffic ⇵ Right-hand traffic No data Left-hand traffic (LHT) and right-hand traffic (RHT) are the practices, in bidirectional traffic, of keeping to the left side and to the ...
The two most important differences between U.S. traffic rules and foreign countries' traffic rules are as follows: Very heavy use of fully-signed, mandatory 4-way stop signs at intersections (rather than 2-way stops, yields, or roundabouts as in other countries) with priority to the first vehicle (priority to the right if two arrive at the ...
Traffic laws govern and regulate traffic, while rules of the road include traffic laws and informal rules that may have developed over time to facilitate the orderly and timely flow of traffic. [1] Organized traffic generally has well-established priorities, lanes, right-of-way, and traffic control at intersections .

The National Highway Traffic Safety Administration writes and enforces the Federal Motor Vehicle Safety Standards. In 2020, there were an estimated 38,680 traffic fatalities in the U.S. [8] The U.S. traffic fatality rate was 1.1 per 100 million vehicle miles traveled as of 2019. [9]
So here’s the paradox: it’s impossible to know all the traffic laws, but you’re responsible for following all of them. Before I reassure you that it’s not as bad as it first appears ...
Priority (right-of-way) rules may vary by country: on a 4-way intersection traffic from the right often has priority; on a 3-way intersection either traffic from the right has priority again, or traffic on the continuing road. For traffic coming from the same or opposite direction, that which goes straight has priority over that which turns off.
RIRO is an important tool of access management, itself an important component of transportation planning.A study applying access management guidelines to the redesign of Missouri Route 763 in Columbia, Missouri [4] illustrates how RIRO, combined with signalized intersections designed to permit U-turns, can accommodate high volumes of traffic with low delay and high safety.
