Tempolimit

Tempolimit is a legally defined maximum speed for a road or traffic zone, indicated by traffic signs and enforced by authorities. It applies to all road users within the area unless stated otherwise. The limit can be expressed in kilometers per hour and is designed to regulate the flow of traffic and reduce risk.

Limits can be fixed (permanent), temporary during road works or hazardous conditions, or dynamic/variable where the limit changes with conditions and is displayed on electronic signs or during adverse weather. Some systems also use a Richtgeschwindigkeit, meaning a recommended speed, which in many jurisdictions is not legally binding, but drivers are expected to adhere to it under normal conditions.

In Germany, for example, there is no universal speed limit on many parts of the Autobahn, although posted limits exist on dangerous or congested sections. A legally non-binding Richtgeschwindigkeit of 130 km/h is commonly cited. Built-up areas typically have explicit limits, such as 30 or 50 km/h, depending on local rules. Other countries have different standard limits for urban, rural, and highway roads.

The purposes of tempolimits include improving road safety, reducing the severity and frequency of crashes, lowering fuel consumption and emissions, and reducing noise. Enforcement methods range from speed cameras to police patrols and automated traffic management systems. Compliance and attitudes toward limits vary by region, road type, and enforcement culture.

Globally, speed limits reflect road design, traffic density, weather, and policy choices. Debates often center on balancing safety and mobility, economic costs, and individual freedom, with ongoing research informing updates to limits and enforcement practices.
