Which side of the road do drivers in Italy drive on?

In Italy, drivers operate their vehicles on the right side of the road. This is consistent with the majority of European countries and aligns with the driving rules in many other parts of the world, particularly those influenced by European driving standards. Driving on the right provides a standardized approach to traffic flow and helps ensure safety on the roads, as it allows for easier navigation and clearer understanding of driving regulations.

The other options suggest alternatives that are not standard practice in Italy. For instance, driving on the left side is common in some countries, such as the United Kingdom, but not in Italy. Center lanes and variable lanes refer to specific roadway configurations that might be used in traffic management but are not indicative of the overall side of the road designated for regular driving. Thus, the correct answer, indicating that drivers in Italy drive on the right side, reflects the established norms and regulations governing road use in the country.
