Mastering the meaning of the 90 km/h speed limit sign is crucial for safe driving and passing your Icelandic theory test. This explanation details why this specific speed restriction is imposed and what factors drivers must consider to ensure compliance and safety on the roads.
Maximum Speed Limit 90 km/h is a restrictive sign that removes a movement, access right, or operating condition that would otherwise be possible. It is used to manage safety, protect vulnerable users, reduce conflict, or keep unsuitable vehicles and behaviour out of a particular road environment. The restriction usually starts at the sign itself and continues until it is cancelled, replaced, or naturally ends according to the road-sign rules. Whenever a supplementary plate is present, it tells you exactly which vehicles, times, distances, or conditions the ban covers.
This sign prohibits or restricts a speed limit restriction from the point where it applies. Drivers must obey the restriction immediately and look for any supplementary plate or end sign that explains the scope, duration, or exceptions.

It might specify that the limit applies only to certain types of vehicles (like trucks or trailers), only during certain times, or for a specific distance. Always read and obey the information on the supplementary plate in conjunction with the main sign.
The speed limit applies from the sign onwards until it is cancelled by an 'End of Speed Limit' sign, replaced by a different speed limit sign, or naturally ends at the next junction or intersection, unless otherwise specified by a supplementary plate. Always be aware of your surroundings and look for signs that may cancel the restriction.
