The highest posted speed limit in the world is 160 km/h (99 mph) on specific highways in the UAE (Abu Dhabi-Al Ain Road & Sheikh Khalifa Highway), while the U.S. has the highest variable limit at 85 mph (137 km/h) on Texas State Highway 130; some parts of Germany's Autobahn have no official limit, but are often variable, and Poland & Bulgaria also feature 140 km/h limits.
The roads that have highest maximum imposed speed limit can currently be found in Poland, where drivers can legally cruise along at a respectable 88 mph (140 km/h), secure in the knowledge that if you increase this to 93 mph you will still not be prosecuted by the police, as they generally only enforce the speed limit ...
Yes — but only in specific conditions. On some unrestricted sections of the German Autobahn, you can legally drive 200 mph (approximately 322 km/h) if your car is capable and the area has no posted speed limit. These stretches are usually outside urban zones, on straight, well-maintained highways with multiple lanes.
In Australia, we have various speed limits depending on the type of road and level of pedestrian activity. The maximum legal speed a car can travel at is 130km/hour, which exists in a section of a highway in the Northern Territory. Speed is the number one killer on Australian roads.
The Basics of Texas Speed Laws
Texas has a maximum established speed limit of 70 miles per hour, according to the Texas Department of Transportation (TxDOT). TxDOT allows local city and state governments to adjust the speed limit up to 85 mph in areas where highway design supports higher speeds.
Portions of the Idaho, Montana, Nevada, North Dakota, Oklahoma, South Dakota, Texas, Utah, and Wyoming road networks have 80 mph (129 km/h) posted limits.
Rural Interstate Limited – 70 MPH. Limited Access Highways – 70 MPH. All Other Roads and Highways – 55 MPH. School Zones – 20 MPH.
Like the rest of mainland Europe, the Germans use km/h rather than mph that we use here in the UK. For cars and motorbikes, the speed limit in towns and cities is 50 km/h (~31 mph) – unless otherwise stated – and 100 km/h (~62 mph) on non-urban/open roads that are not the motorway/autobahn.
On some sections of the Northern Territory's Barkly, Stuart, Victoria and Arnhem highways, the maximum speed limit is 130km/h. Previously, a section of the Stuart Highway between Alice Springs and Tennant Creek had an open speed limit, making it the only road in Australia with no speed limit at all.
In Australia, speeding is driving even 1 km/h over the posted speed limit. Unlike in some countries where limits are treated as guidelines, Australia enforces strict speed limit penalties.
Germany is the only country where some motorways do not have a maximum speed limit. The 130 km/h is sign-posted as a general advisory speed limit for motorways in the entry of the country. Due to those Autobahns, Germany is considered a country without a general speed limit on its highways.
More than half of the total length of the German autobahn network has no speed limit, about one third has a permanent limit, and the remaining parts have a temporary or conditional limit. Some cars with very powerful engines can reach speeds of well over 300 km/h (190 mph).

Rules of the road in Russia
In residential areas, the speed limit is 20km/h, while in other urban areas, it's 60km/h. Outside built-up areas, the limit is 90km/h, increasing to 110km/h on expressways.
Today there are seemingly no end of supercars that can top the double ton, but back in the 1990s there were only a handful of machines that could reach 200mph. And getting to that magic mark wasn't easy remembers Nik Berg. There is just one country on earth where you can legally drive as fast as you dare: Germany.
Key points. Most people know the dangers of driving too fast. But driving too slowly is dangerous as well… and is illegal in all states in Australia. The law on what is too slow is set out in road rule 125, and requires that 'a driver must not unreasonably obstruct the path of another driver or pedestrian.
The section between Balladonia and Caiguna includes what is regarded as the longest straight stretch of road in Australia and one of the longest in the world. The road stretches for 146.6 kilometres (91.1 mi) without turning, and is signposted and commonly known as the "90 Mile Straight".
Autobahn, Germany
A road without speed limits might sound like an accident waiting to happen, but the autobahn is among the safest highway networks in the world.
The German government recommends a maximum speed of 130 kilometres per hour (around 80 mph) on autobahns, but drivers are still free to push the limits in de-restricted sections. That's right—there's no speed limit in certain areas!
Where are the no-speed-limit sections on the Autobahn? Germany's Autobahn has several stretches without speed limits. These are mostly found in rural areas such as A9 near Bayreuth, A20 in Mecklenburg, and parts of A24 between Berlin and Hamburg. Speed is advised, but not legally capped in these zones.
The highest speed limit in the country is 85 mph (137 km/h), which is posted on a single stretch of tollway in exurban areas outside Austin, Texas. The lowest maximum speed limit in the country is 30 miles per hour (48 km/h) in American Samoa.
In NSW the maximum speed limit for a vehicle more than 4.5 tonnes Gross Vehicle Mass (GVM) is 100 km/h. For certain road conditions, such as sharp bends, steep descents and winding roads, special speed limit signs may be posted for trucks, road trains and buses.
Speed limits
Generally, the speed limit in Finland is 50 km/h in built-up areas and 80 km/h outside of them. Both limits are typically enforced if there is no other speed limit posted. On major highways in summer, you can drive 100 km/h. On motorways, the summertime limit is 120 km/h.
