Apparently 60km.. received a fine for doing 85km in the "60km" zone. I honestly dont remember seeing any speed signs!! Quite annoyed!!
The distance is approx. 630 km's. With an average speed limit of 120 kmh, it would take yu about 5 and half hours from Johannesburg to Durban
They are as high as 65. In North Dakota, the speed limit is 65 mph on two-lane highways if posted for that speed.
75
There is a stretch of Texas state route 130 north of San Antonio with a posted speed limit of 85 mph (137 kph).
15 mph
99%
Somewhere north of 200mph, which is way unsafe for the road.
5 mph
826 limit
the posted speed limit
When another speed limit sign is reached that changes the limit from the previously posted one.
The speed limit is exactly that - the speed limit. While a reasonable excess of speed might be overlooked when overtaking another vehicle, there is no guarantee. You can be pulled over and cited for speeding, still.
