What is the maximum speed limit on an express road when marked by standard road signs, outside built-up areas?

The maximum speed limit on an express road, when marked by standard road signs and located outside built-up areas, is indeed 120 km/h. This limit is established to facilitate efficient traffic flow on expressways while ensuring safety. Express roads typically accommodate higher-speed traffic and are designed with features such as multiple lanes and limited access points that allow for quicker travel between destinations.

The 120 km/h limit is a standard regulation in many countries, recognizing that vehicles can operate safely at this speed on roads that have been built to handle it. The design and engineering of express roads contribute to establishing this limit, providing sufficient space for vehicles to maneuver while maintaining safe distances from each other.

Other speed limits like 90 km/h, 50 km/h, or 30 km/h are usually applicable in different contexts, such as on regular roads in urban environments, near schools, or in residential areas, where the emphasis is more on safety and pedestrian access rather than maintaining high-speed traffic flow.
