Traffic rules
Iceland
1. Width limit
A width limit prohibits vehicles or vehicle combinations whose total width exceeds the value shown from entering or passing a road section, bridge, tunnel, gateway or other narrow passage. The width includes the vehicle’s load and any equipment or objects extending from its sides.
Drivers must know the maximum travelling width of their vehicle and load, observe advance warnings and use an alternative route when necessary. They should never enter when sufficient lateral clearance is uncertain.
What does a posted vehicle-width restriction mean in Iceland?
The maximum-width sign prohibits vehicles wider than the stated limit. Check the vehicle and its load against the actual sign and any applicable exception. A passage that looks wide enough does not remove the signed restriction.

How should you check the width of a loaded vehicle in Iceland?
Check the vehicle width including its load against the signed limit. Allow physical clearance for projecting fittings and equipment, including mirrors, as well. A legal width measurement does not by itself guarantee enough room through the passage.

Can a driver ignore a width restriction if the road looks wide enough in Iceland?
No. A regulatory width limit must be obeyed unless an applicable exemption or authorised arrangement permits entry. Check your route before driving a wide van, trailer or load through a narrow town, bridge or roadworks section.
