The **speed limits** are established considering several **criteria** to ensure safety and comfort in traffic. These criteria include:

- **Type of road**: The characteristics of the road, such as whether it is a motorway, dual carriageway, road, or path, influence the speed limits. For example, on motorways and dual carriageways, the maximum speed is 120 km/h, while on roads it is 90 km/h, and on paths it is 30 km/h.

- **Road conditions**: The design speed of the road, which is the maximum safe speed for which it was built, is also considered. This ensures that vehicles can travel safely.

- **Degree of congestion**: In urban areas, where there is more traffic and pedestrians, speed limits are lower to reduce the risk of serious accidents. For example, within towns and cities, the maximum speed is 50 km/h to increase the chances of survival in case of a collision.

These criteria ensure that speed limits are not set arbitrarily, but based on factors that promote road safety.
