Right- and left-hand traffic in the fictional world

This is a list of countries keeping to the left and to the right, sorted by alphabetical order. Warning: This relates to roads and highways.

Republic of Guy
Republic of Guy currently drives on the right.

However on May 5, 1969, John Terry ordered the country to begin banning RHD vehicles. This related to just large cities (Guy City, Rouz, etc.), where RHD vehicles would be allowed in smaller areas. The left-hand traffic was in force until March 24, 1989 across the country, when at midnight it switched to the right. Larger cities switched to the right in 1971.
