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 Czechia?

A width restriction limits entry to a passage that cannot legally accommodate vehicles above the indicated width. Look for the local sign near town-centre streets and rail bridges and read any advance warning or exception plate. Measurements are generally given in metres.

How should you check the width of a loaded vehicle in Czechia?

For Czech width restriction B15, the actual width includes the load and rear-view mirrors. Check all projecting equipment as well as the vehicle’s body, and ensure there is enough physical clearance. Do not substitute an unladen registration dimension or assume that mirrors are excluded from this sign’s measurement.

Can a driver ignore a width restriction if the road looks wide enough in Czechia?

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.
