Speed limits in the Isle of Man are measured in miles per hour, and the same basic design of road signs is used as in the United Kingdom.
As a self-governing British Crown Dependency outside the United Kingdom, the island's parliament can enact its own legislation, including road traffic laws such as speed limits and the power to close roads to allow races such as the Isle of Man TT to take place.
Drivers are limited to 50 miles per hour (80 km/h) in the first full year after passing their driving test (Isle of Man citizens are permitted to start driving at the age of sixteen)[1] and some are not used to having to make progress in the same way as on a larger road network such as that in the UK: even a cautious driver can get from anywhere in the island to anywhere else in no more than sixty minutes.
In an official survey in 2006, the introduction of blanket speed limits was refused by the population.
[2] Due to the COVID-19 pandemic, an island-wide temporary speed limit of 40 mph (64 km/h) was introduced in 2020,[3] later increasing to 60mph (97 km/h).
