Driving below the **minimum permitted speed** can be dangerous and cause accidents. This is because an abnormally reduced speed can surprise other drivers, who do not expect to encounter such slow vehicles on the road. For example, on a motorway where the minimum speed is 60 km/h, driving at 40 km/h is considered an abnormally reduced speed.


Furthermore, it is prohibited to drive below the minimum speed, even if there are no other vehicles on the road. The only exceptions are situations such as heavy traffic, breakdowns, poor road conditions, or if the vehicle is special, like a bicycle or one drawn by animals.

Therefore, it is important to respect the minimum speed limits to avoid risky situations and ensure road safety.
